     BACKGROUND OF THE INVENTION 
     The present invention relates generally to vehicle protection barriers, and more particularly to movable water ballasted vehicle traffic protection barriers for applications such as pedestrian protection, traffic work zone separation, airport runway divisions, and industrial commercial uses. More particularly, the present invention relates to reflective nose sheeting for vehicle protection barriers, and like. 
     The invention, together with additional features and advantages thereof, may best be understood by reference to the following description taken in conjunction with the accompanying illustrative drawings. 
     SUMMARY OF THE INVENTION 
     The present invention comprises an end treatment array for attenuating the forces generated by a vehicular impact. The inventive end treatment array include a transition barrier module comprising first and second side walls, first and second end walls, a top wall, and a bottom wall, wherein the module walls together define a substantially enclosed interior space. The transition barrier module has a predetermined width and length. The end treatment array advantageously further includes an innovative containment impact sled which comprises an axially extending frame. The frame has a width sufficient to contain the transition barrier module within the frame when in an assembled configuration, and has an axial length which is at least one-half the length of the transition barrier module. The frame defines an interior volume, the purpose of which is to contain a substantial portion of the transition barrier module in the assembled configuration, and to contain debris caused by destruction of the plastic barrier modules in a vehicular impact. The containment impact sled is attached to the transition barrier module in the aforementioned assembled configuration. 
     As noted above, the transition barrier module is fabricated of plastic. Importantly, the interior space is hollow and, unlike the regular barrier modules, is unfilled with any ballasting material for maximum initial energy absorption. The containment impact sled further comprises an upright wall connected to the frame which substantially covers the first front-facing end wall of the transition barrier module when the sled is in its assembled configuration, with the transition barrier module at least partially contained within the frame of the sled. The containment impact sled further comprises a floor. 
     The containment impact sled frame comprises a first side frame member attached to one side of the floor and upright wall and a second side frame member attached to an opposing side of the floor and the upright wall. Each of the side frame members comprise a bottom frame member and a top frame member, wherein the bottom frame member is disposed substantially horizontally, and the top frame member extends downwardly at an angle from its frontmost end to its rearmost end, with the frontmost end of the top frame member being connected to the upright wall near a top of the upright wall and the rearmost end of the top frame member being connected to a rearmost end of the bottom frame member near ground level, such that each side frame member is triangular in shape. 
     Apertures are provided in each of the transition barrier module and the sled, which are aligned when the transition barrier module and the sled are in the assembled configuration. A pin extends through the aligned apertures in the assembled configuration to attach the transition barrier module to the sled. The transition barrier module comprises a plurality of vertically spaced lugs on the first end wall, wherein each of the lugs have one of the apertures therein for receiving the pin. Additionally, one of the apertures is disposed in the upright wall of the sled. 
     Preferably, the transition barrier module comprises holes in a lower end thereof to prevent the containment of ballasting material in the interior space. 
     The end treatment array further comprises a plurality of vertically spaced lugs on the second transition barrier module end wall, for attaching the transition barrier module to a first end of an adjacent barrier module. In certain arrays, the adjacent barrier module is also a transition barrier module, constructed similarly to the first transition barrier module, and is also unfilled with ballasting material. The array further comprises a barrier module connected at a first end to the transition barrier module which is filled with a ballasting material, which is preferably water. 
     It should be noted that it is within the scope of the present invention to employ any number of transition barrier modules and any number of ballasted barrier modules in the array, depending upon desired crash attenuation characteristics and particular roadway conditions. So, the use of the term “connected” or “attached” herein does not necessarily mean a direct connection or attachment, but could mean an indirect connection through intermediate modules, unless specific language used requires otherwise. Importantly, for ease of assembly by on-site personnel, the transition barrier modules and the ballast-filled barrier modules are differently colored. 
     Another important aspect of the present invention is that the end treatment array comprises a second transition barrier module connected at a first end thereof to a second end of the barrier module, wherein the second transition barrier module is constructed substantially similarly to the first transition barrier module and is unfilled with ballasting material. This second end of the end treatment array is adapted for attachment to the fixed structure, such as a concrete abutment, which is being protected. Thus, end treatment hardware is provided for attaching a second end of the second transition barrier module to the fixed structure. The end treatment hardware, in disclosed embodiments, comprises a metal frame which is securable to the second end of the second transition barrier module. The frame comprises a plurality of vertically spaced horizontal cross members, each of which has an aperture in a middle portion thereof for receiving a pin, wherein in an assembled state the apertures are aligned. Additional components of the end treatment hardware are first and second hinge posts disposed at opposing ends of each of the assembled vertically spaced horizontal cross members, a first hinge pin, a second hinge pin, a left panel, and a right panel. The left panel is pivotally securable to aligned first hinge posts using the first hinge pin and the right panel is pivotally securable to aligned second hinge posts using the second hinge pin, so that the left and right panels can be rotated to extend along a length of the fixed structure. Each of the left and right panels have apertures therein for receiving hardware to secure each panel to the fixed structure. A pin is provided for insertion into the aligned apertures on each of the plurality of vertically spaced horizontal cross members. 
     In another aspect of the invention, there is provided a containment impact sled for use in an end treatment array for attenuating the forces generated by a vehicular impact, which comprises a frame extending in an axial direction and comprising a first side frame member, a second side frame member spaced from the first side frame member, and an end frame member extending across a width of the frame and securing the first side frame member to the second side frame member. The frame members together define an interior space. The containment impact sled is adapted for attachment to an adjacent barrier module in an assembled end treatment array, in such a manner as to contain a substantial portion of the adjacent barrier module within the interior space when the end treatment array is assembled. 
     The frame further comprises a floor attached to and extending between each of the side frame members and the end frame member, and further comprises an upright wall attached to a front end of the end frame member. The upright wall comprises an end cap. Each of the side frame members comprise a bottom frame member and a top frame member, wherein the bottom frame member is disposed substantially horizontally, and the top frame member extends downwardly at an angle from its frontmost end to its rearmost end, with the frontmost end of the top frame member being connected to the end frame member near a top of the end frame member and the rearmost end of the top frame member being connected to a rearmost end of the bottom frame member near ground level, such that each side frame member is triangular in shape. 
     An aperture is provided in the upright wall for attaching the containment impact sled to an adjacent barrier module. The frame is preferably comprised of metal, though it would not necessarily have to be, if another suitably durable material were available. 
     In yet another aspect of the invention, there is disclosed a method of assembling an end treatment array for protecting a fixed structure from an impact by a passing vehicle. The method comprises steps of securing a plurality of ballast-filled hollow plastic barrier modules together in an axial array and securing one end of a transition barrier module to one end of the array of ballast-filled hollow plastic barrier modules. The transition barrier module is unfilled with ballasting material. A further method step is to secure a containment impact sled to the other end of the transition barrier module, wherein the containment impact sled comprises a frame defining an interior space, and wherein the securing step includes disposing the frame about the transition barrier module so that a substantial portion of the transition barrier module is contained within the interior space. 
     The securing step further comprises inserting a pin through aligned holes in both the containment impact sled and the transition barrier module and a step of securing a second transition barrier module to a second end of the axial array of ballast-filled barrier modules, wherein the second transition barrier module is unfilled with ballasting material. Additionally, the method comprises a step of securing the second transition barrier module to the fixed structure, using end treatment hardware comprising metal cross-members attached to the second transition barrier module and metal plates pivotally mounted to the metal cross-members. 
     In still another aspect of the invention, there is provided a portable reflective sheeting system for securement to a desired traffic management device. The system comprises a square panel having a first face and a second face and four substantially equal edges. Reflective sheeting displaying a first striping pattern is disposed on the first face of the panel. Reflective sheeting displaying a second different striping pattern is disposed on the second face of the panel. Fastener holes are disposed along each of the four edges of the panel, the holes being substantially evenly spaced about a perimeter of the panel. Preferably, there is a fastener hole disposed at each corner of the panel, and an additional fastener hole disposed on each edge of the panel at a location substantially equidistant from the two closest corner fastener holes. One of the first and second striping patterns comprises a plurality of stripes of alternating colors extending diagonally across the panel face. When one of the first and second striping patterns is reoriented, by reorienting the panel, the diagonal stripes extend in a different diagonal direction to denote a different traffic condition. 
     The panel may be secured with either the first or second face thereof facing outwardly, to thereby display a selected one of the first and second striping patterns. 
     In yet another aspect of the invention, there is provided a portable reflective sheeting system for securement to a desired traffic management device. The system comprises a square panel having a face and four substantially equal edges. Reflective sheeting displaying a striping pattern is disposed on the face of the panel. Fastener holes are disposed along each of the four edges of the panel, the holes being substantially evenly spaced about a perimeter of the panel. More particularly, there is a fastener hole disposed at each corner of the panel, and an additional fastener hole disposed on each edge of the panel at a location substantially equidistant from the two closest corner fastener holes. 
     The striping pattern comprises a plurality of stripes of alternating colors extending diagonally across the panel face. When the striping pattern is reoriented, by reorienting the panel, the diagonal stripes extend in a different diagonal direction to denote a different traffic condition. 
     In still another aspect of the invention, there is disclosed a method of conveniently displaying a desired reflective sheeting striping pattern on a traffic management device, which comprises steps of identifying a particular striping pattern to be displayed, procuring a portable panel having reflecting sheeting affixed to a face thereof, orienting the portable panel at a desired location on the traffic management device, and affixing the panel to the device using fastener holes disposed about a perimeter of the portable panel. The method may comprise a further step of changing the particular striping pattern to be displayed by removing the panel from the traffic management device, turning the panel over to display an opposing side thereof, on which is displayed a different particular striping pattern, and reattaching the panel to the traffic management device so that the opposing side of the panel is displayed. 
     Alternative, the method may comprise a further step of changing the particular striping pattern to be displayed by removing the panel from the traffic management device, rotating the panel by 90 degrees, 180 degrees, or 270 degrees, and then reattaching the panel to the traffic management device so that the particular striping pattern is oriented in a different direction. 
     The invention, together with additional features and advantages thereof, may best be understood by reference to the following description taken in conjunction with the accompanying illustrative drawings.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring now more particularly to the drawings, there is shown in  FIGS. 1-3 and 15-17  a water-ballasted barrier segment or module  10  constructed in accordance with one embodiment of the present invention. The illustrated barrier module preferably has dimensions of approximately 18 in. W×32 in. H×78 in. L, with a material thickness of about ¼ in. The material used to fabricate the module  10  may be a linear medium density polyethylene, and is preferably rotationally molded, although it may also be molded using other methods, such as blow molding. The module  10  preferably has an empty weight of approximately 75-80 lb., and a filled weight (when filled with water ballast) of approximately 1100 lb. 
     Particularly with respect to  FIGS. 1-2 , the barrier module  10  has been constructed using a unique concave redirective design, wherein outer walls  12  of the barrier module  10  are configured in a concave manner, as shown. In a preferred configuration, the concave section is approximately 71 inches long, and runs the entire length of the barrier module. The concave section is designed to minimize the tire of a vehicle, impacting the barrier along the direction of arrow  14 , from climbing up the side of the barrier module, by pocketing the tire in the curved center portion of the barrier wall  12 . When the vehicle tire is captured and pocketed inside the curved portion, the reaction force of the impact then diverges the vehicle in a downward direction, as shown by arrow  16  in  FIG. 1 . The concave diverging design will thus assist in forcing the vehicle back toward the ground rather than up the side of the water barrier module  10 . In a preferred configuration, as shown in  FIG. 1 , the concave center portion of the outer wall  12  has a curve radius of approximately 24¾ in., and is about 23 inches in height. 
       FIGS. 3-11  illustrate an interlocking knuckle design for securing adjacent barrier modules  10  together. The interlocking knuckle design is a lug pin connection system, comprising four lugs  18  disposed in interweaved fashion on each end of the barrier module  10 . Each lug  18  is preferably about 8 inches in diameter, and approximately 2 inches thick, although various dimensions would be suitable for the inventive purpose. To achieve the interweaved effect, on a first end  20  of the barrier module  10 , the first lug  18  is disposed 4 inches from the top of the module  10 . The remaining three lugs  18  are equally spaced vertically approximately 3½ inches apart. On a second end  22  of the barrier module  10 , the first lug  18  is disposed about 7 inches from the top of the barrier module  10 , with the remaining three lugs  18  being again equally spaced vertically approximately 3½ inches apart. These dimensions are preferred, but again, may be varied within the scope of the present invention. 
     When the ends of two adjacent barrier modules  10  are placed together, as shown sequentially in  FIGS. 7 and 8 , the complementary lugs  18  on the mating ends of the adjoined modules  10  slide between one another in interweaved fashion, due to the offset distance of each lug location, as described above, and shown in  FIGS. 4 and 7 . The lugs&#39; dimensional offset permit each module  10  to be linked together with one lug atop an adjacent lug. This results in a total of eight lugs on each end of the water barrier module  10  that lock together, as seen in  FIG. 8 . Each lug  18  has a pin receiving hole  24  disposed therein, as best shown in  FIGS. 9 and 10 . When the eight lugs  18  are engaged, as discussed above, upon the adjoining of two adjacent barrier modules  10 , these pin receiving holes  24 , which are preferably approximately 1½ inches in diameter, and are disposed through the two inch thick portion of the lug  18 , correspond to one another. Thus, a T-pin  26  is slid vertically downwardly through the corresponding pin receiving holes  24  of all eight lugs or knuckles  18 , as shown in  FIG. 8 , in order to lock the two adjoined barrier modules  10  together. 
     To reduce the bearing load on the pin lug connection, a double wall reinforcement  28  may be included on the backside of the hole  24  on the lug  18 , as shown in  FIG. 10 . The double reinforced wall is created by molding an indentation  30  on an outer curved section  32  of the lug  18 , as shown in  FIG. 9 . The removal of material on the outside curved section  32  of the lug  18  creates a double reinforced wall on the inside section of the lug. The wall created by the recessed section  30  on the outside of the lug creates a reinforcement section  28  against the vertical hole  24  in the lug  18 , as shown in sectioned  FIG. 10 . By creating this double wall reinforcement section  28 , the T-pin  26  has two approximately ¼ inch thick surfaces to transfer the load to the T-pin  26  during vehicular impact. This arrangement will distribute the bearing load over a larger area, with thicker material and more strength. 
     During impact, the water barrier can rotate at the pin lug connection, resulting in large stresses at the pin lug connection during maximum rotation of the water wall upon impact. To reduce the stresses at the pin lug connection, a concave inward stress transfer zone is formed between the male protruding lugs  18 , as shown in  FIGS. 12-14 . The concave inward section creates a concave female portion  34  at the ends of each water wall module where the male end of each lug  18  will slide inside when aligned, as illustrated. Before vehicular impact, the male lugs  18  are not in contact with any surface inside the concave female portion  34  of the barrier module  10 . However, when the module  10  is impacted, and is displaced through its full range of rotation (approximately 30 degrees), as shown in the figures, the external curved surface of the male lugs will come into contact with the external surface of the inside wall of the concave female portion, as shown in  FIG. 14 . This transfers the load from the pin lug connection to the lug contact point of the male/female portion. By transferring the load of the vehicular impact from the pin lug connection to the female/male contact point, the load is distributed into the male/female surface contact point before the pin connection begins to absorb the load. This significantly reduces the load on the T-pin  26 , minimizing the pin&#39;s tendency to bend and deform during the impact. 
     To accommodate the ability to dispose a fence  36  or any other type of device to block the view or prevent access to the other side of the barrier  10 , the t-pins  26  are designed to support a square or round tubular fence post  38 , as shown in  FIG. 18 . The tubular post  38  is adapted to slip over the t-pin, with suitable retaining structure disposed to ensure that the post  38  is firmly retained thereon. 
     In a preferred method, each barrier module  10  is placed at a desired location while empty, and relatively light. This placement may be accomplished using a forklift, for example, utilizing forklift apertures  39 . Once the modules are in place, and connected as described above, they can then be filled with water, using fill apertures  39   a  as shown in  FIG. 3 . When it is desired to drain a barrier module, drain apertures, such as aperture  39   b  in  FIG. 15 , may be utilized. 
     Now referring in particular to  FIGS. 19-21 , a second embodiment of a water-ballasted barrier module  110  is illustrated, wherein like elements are designated by like reference numerals, preceded by the numeral 1. This barrier module  110  is preferably constructed to have overall dimensions of approximately 22 in. W×42 in. H×78 in. L, with a material thickness of about ¼ inches. As in the prior embodiment, these dimensions are presently preferred, but not required, and may be varied in accordance with ordinary design considerations. The material of which the barrier module  110  is fabricated is preferably a high density polyethylene, and the preferred manufacturing process is rotational molding, although other known processes, such as blow molding, may be used. 
     The illustrated embodiment utilizes a unique configuration to minimize that chances that an impacting vehicle will drive up and over the module  110  upon impact. This configuration comprises a saw tooth profile, as illustrated, which is designed into the top portion of the barrier module  110 , as shown in  FIGS. 19-24 . The design intent of the saw tooth profile is to snag the bumper, wheel, or any portion of a vehicle impacting the barrier  110  from a direction indicated by arrow  114  ( FIG. 23 ) and to deflect the vehicle in a downward direction as indicated by arrow  116  ( FIG. 23 ). The saw tooth profile shape runs the entire length of each section of the barrier module  110 , as shown. A first protruding module or sawtooth  40 , forming the sawtooth profile, begins to protrude approximately 20 inches above the ground, and second and third protruding modules  42 ,  44 , respectively are disposed above the module  40 , as shown. Of course, more or fewer sawtooth modules, or anti-climbing ribs, may be utilized, depending upon particular design considerations. The design intent of using a plurality of sawtooth modules is that, if the first anti-climbing rib  40  does not succeed in containing the vehicle and re-directing it downwardly to the ground, the second or third climbing ribs  42 ,  44 , respectively, should contain the vehicle before it can successfully climb over the barrier  110 . 
     The first embodiment of the invention, illustrated in  FIGS. 1-18 , is capable of meeting the earlier described TL-1 crash test, but plastic construction alone has been found to be insufficient for withstanding the impact of a vehicle traveling 70 kph or 100 kph, respectively, as required under TL-2 and TL-3 testing regimes. The plastic does not have sufficient physical properties alone to stay together, pocket, or re-direct an impacting vehicle at this velocity. In order to absorb the energy of a vehicle traveling at 70 to 100 kph, the inventors have found that steel components need to be incorporated into the water barrier system design. Using steel combined with a large volume of water for ballast and energy absorption enables the properly designed plastic wall to absorb the necessary energy to meet the federal TL-2 and TL-3 test requirements at such an impact. 
     To contain the 70 to 100 kph impacting vehicle, the inventors have used the interlocking plastic knuckle design described earlier in connection with the TL-1 water barrier system described and shown in  FIGS. 1-18  of this application. The same type of design principles are used in connection with this larger and heavier TL-2 and TL-3 water barrier system, which includes the same interlocking knuckle attachment system disclosed in connection with the first embodiment. 
     The TL-2 and TL-3 barrier system described herein in connection with  FIGS. 19-31  absorbs energy by plastic deformation, water displacement, wire rope cable fencing tensioning, water dissipation, and overall displacement of the water barrier itself. Since it is known that plastic alone cannot withstand the stringent test requirements of the 70-100 kph TL-2 and TL-3 vehicular impact protocols, internally molded into the barrier module  110  is a wire rope cable  46 , which is used to create a submerged fence inside the water barrier module  110  as shown in  FIGS. 25 and 26 . Before the barrier module  110  is molded, the wire rope cables  46  are placed inside the mold tool. The cables are made with an eyelet or loop  48  ( FIG. 30 ) at each end, and are placed in the mold so that the cable loops  48  wrap around the t-pin hole  124  outside diameter as shown in  FIG. 27 . Preferably, the wire rope cables  46  are each comprised of stainless steel, or galvanized and stranded steel wire cable to resist corrosion due to their contact with the water ballast, and are preferably formed of ⅜ inch 7×19 strands, though alternative suitable cable strands may be used as well. By placing the cables  46  around the t-pin holes  124 , dual fence posts are created on each side of the barrier module  110 , with four cable lines  46  disposed in between, thereby forming an impenetrable cable fence in addition to the water ballast. It is noted that the wire cable loop ends are completely covered in plastic during the rotational molding process, to prevent water leakage. 
     By placing the wire rope cable  46  and wrapping it around the t-pin hole  124 , a high strength area in the interlocking knuckles is created. When the t-pin  126  is dropped into the hole  124 , to connect a series of barrier fence modules  110 , it automatically becomes a steel post by default, since the wire rope cable modules  46  are already molded into the barrier modules. Since the loop of each cable end wraps around the t-pin in each knuckle, the impacting vehicle will have to break the wire rope cable  46 , t-pin  126 , and knuckle in order to break the barrier.  FIGS. 28-30  illustrate how the wire rope cables  46  wrap the T-pin holes  124 . 
     The wire rope cables  46  are an integral part of each barrier module  110 , and cannot be inadvertently omitted or removed once the part has been manufactured. The current design uses up to four wire rope cables  46  per barrier module  110 , as illustrated. This creates an eleven piece interlocking knuckle section. More or fewer knuckles and wire rope cables may be utilized, depending upon whether a lower or taller barrier is desired. The wire rope fence construction disclosed in connection with this second TL-2 or TL-3 embodiment can also be incorporated into the lower height barrier illustrated and described in  FIGS. 1-18 . When large numbers of barrier modules are used to create a longitudinal barrier, a wire rope cable fence is formed, with a t-pin post, with the whole assembly being ballasted by water without seeing the cable fencing.  FIG. 31  illustrates such a plurality of modules  110 , interlocked together to form a barrier as just described. As illustrated, each barrier module is approximately 2100 lb when filled with water. 
     As the barrier illustrated in  FIG. 31  is impacted by a vehicle, the plastic begins to deform and break, the barrier wall in the impact zone begins to slide, further absorbing energy, water ballast is displaced, and water is dispersed while the wire rope cables  46  continue the work of absorbing the impact energy by pulling along the knuckles and placing the series of wire rope cables in tension within the impact zone. The entire area of impact immediately becomes a wire rope cable fence in tension, holding the impacting vehicle on one side of the water ballasted barrier. Otherwise, the normal status of the barrier is for the wire rope cables  46  to be in a slack state. The excellent energy absorption of this system is enhanced by the progressive nature of the events that occur, in sequence, as described above, resulting in a progressive deceleration of the vehicle and full absorption of the impact energy with minimum harm to vehicle occupants and nearby vehicles, pedestrians, and structures. 
     With reference particularly to  FIGS. 32-34 , an inventive embodiment of the drain aperture  39   b  will be more particularly described. This particular feature is applicable to any of the above described embodiments of the invention. The aperture  39   b  is disposed within a recess  50  in a bottom portion of the barrier module  10 . A closure or cap  52  is provided for closing and sealing the aperture  39   b  to prevent leakage of ballast from the barrier module  10 . The closure  52  is secured in place by means of a series of buttress threads  54  ( FIGS. 33, 34 ). The buttress threads  54  are coarse and square cut, with flat edges  55 , and advantageously function to create a hydraulic seal through the interference fit between the threads  54  on the aperture  39   b  and mating threads  56  on the closure  52 . The closure  52  comprises, in the preferred embodiment, a plastic plug which is threaded into the barrier module outer wall  12  by means of the interengaging buttress threads  54 ,  56 , as described above. A sealing washer on the plug  52  seats, in a flat profile, on the sealing surface on the barrier wall  12  once the threads are engaged and tightened. This flat profile results in a lower chance of leakage, with no need to over-tighten the plug  52 . Advantageously, the unique design results in a much reduced chance of cross-threading the plug when threading it into the wall, compared with prior art approaches, and it is much easier to start the thread of the plug into the barrier wall. Because of the recess  50 , the plug  52  is flush or even recessed relative to the wall, which reduces the chances of damage to the plug during use. 
     The thread  54  is uniquely cast-molded into the wall, which is typically roto-molded. Avoidance of spin-welding, which is a typical prior art technique for fabricating threads of this type in a roto-molded device, surprisingly greatly reduces the chance of damage to the barrier and closure due to cracking and stripping. 
     Referring now to  FIGS. 35-41 , yet another modified embodiment of the present invention is illustrated, wherein like elements to those in the previous embodiments are designated by like reference numerals, preceded by the numeral  2 . Thus, in  FIGS. 35 and 36  a barrier module  210  is shown, which is similar in many respects to barrier module  110 , but differs in ways that will be described herein. The barrier module  210  comprises forklift and pallet jack lift points  239  disposed on a bottom edge of the module, as well as a second set of forklift lift points  239  disposed above the first set. A drain aperture  239   b  is disposed between the two lower lift points  239 . The drain aperture preferably employs the cap and buttress thread features illustrated and described in connection with  FIGS. 32-34 . A fill aperture  239   a  is disposed on a top surface of the module, having a diameter, in one preferred embodiment, of approximately 8 inches. Advantageously, the fill aperture also comprises a lid  58 , which is molded with fittings designed to ensure water-tight securement with an easy ¼ turn of the lid. As illustrated, each barrier module weighs approximately 160 lb when empty, and approximately 2000 lb when filled with approximately 220 gallons of water. The module  210  is approximately 72 inches in length (excluding the lugs), 46 inches in height, and 22 inches wide. 
     In the illustrated embodiment, the right side of each barrier module  210  preferably includes five lugs  218 , while the left side comprises six lugs  218 . These lugs are configured to be interleaved when two adjacent barrier modules  210  are joined, as in the prior embodiments, so that the pin receiving holes  224  are aligned for receiving a T-pin  226 . The T-pin  226  comprises a T-pin handle  60  at its upper end, and a keeper pin  62  insertable through a hole in its lower end, as illustrated in  FIG. 36 . To join the barrier modules  210  together, the T-pin  226  is inserted downwardly through all of the aligned holes  224 . Then, the keeper pin  62  is inserted through the hole in the lower end of the pin  226 , to ensure that the T-pin cannot be inadvertently removed. In a preferred embodiment, the diameter of the T-pin is approximately 1¼″. 
     Stacking lugs  64  are disposed on the top surface of each barrier module, and corresponding molded recesses  65  are disposed in the lower surface of the barrier module  210 . Thus, as shown in  FIGS. 42 and 43 , the barrier modules  210  may be stacked vertically, with the stacking lugs  64  on the lower barrier module  210  engaging with their counterpart stacking recesses  65  on the upper barrier module  210 . Two barrier modules, stacked vertically, have a total height of approximately 87 inches, in one preferred embodiment. 
     One significant difference between the embodiment of  FIGS. 19-31  and the embodiment of  FIGS. 35-41  is the particular design of the sawtooth modules  240 ,  242 , and  244 . As is evident from inspection of the various figures, the latter embodiment retains substantially flat barrier side walls, with recesses into which the sawtooth modules extend, in an upward slanting direction, as shown. The resulting anti-climb function is similar to that of the  FIGS. 19-31  embodiment, but the manufacturing process is greatly simplified. In one preferred embodiment, the angle of slant of each sawtooth module is approximate 43 degrees. 
     Now, with reference particularly to  FIGS. 37-41 , details of the innovative wire rope cable system are illustrated. In this embodiment, an insertion sleeve or bushing  66  is molded into each lug or knuckle  218 , where a wire rope cable  246  is placed. The bushing  66  is preferably cylindrical, and its interior diameter comprises the pin receiving hole  224  of the corresponding knuckle  218  in which the bushing is molded. The bushing  66  is preferably comprised of steel, though other suitable materials may be employed. As in prior embodiments, the wire rope cables preferably comprise ⅜ inch 7×19 galvanized steel cable, though other suitable materials may also be utilized. Because of the advantageous molding techniques of the present invention, which causes the cable loops  248  to be completely encapsulated in molded plastic, stainless steel cables need not be used. The inventors have found that galvanized braided carbon steel cable is stronger. Both the bushing  66  and the cable  246  is preferably hot-dipped galvanized. 
     Each end of the steel cable  246  is extended around the bushing  66  to form eyelet or loop  248 , and secured to the remaining cable  246  by a swage or clamp  68 . The bushing  66  is sized to allow it to be inserted into the mold prior to molding. The assembly illustrated in  FIG. 38  is then placed in the barrier module mold (not shown), together with the other similar assemblies, preferably four in total, as shown in  FIG. 36 , so that corresponding knuckles  218  on each side of the barrier are tied together by a wire rope cable assembly  246 . The cables are relatively taut when placed into the mold. When the rotational molding process is completed, including the cooling of the barrier module, the cables become slack. The amount of slack contributes to the effectiveness of the bushing-cable assembly during an impact by allowing the plastic and the water to absorb some of the impact energy before the cables are engaged. The bushing and a portion of the cable loop become encapsulated in plastic as a result of the molding process, forming an integrally molded-in, leak-proof connection. 
     In a preferred configuration, the bushing  66  comprises steps  70  at the top and bottom ends thereof. The bushing  66  is approximately 3⅛″ in length, with a 1¼″ ID and a 1¾″ OD. The steps  70  are preferably approximately 0.095 inches, and serve to create an edge for plastic to form an extra thick layer around the top and bottom sections of the bushing during the molding process. By creating the thicker plastic layer in these portions, the sleeve edge design inherently prevents water from leaking at these top and bottom edges. This thicker plastic layer prevents water seepage from occurring between the steel and plastic mating surfaces. The entire assembly of a wire rope cable  246  and, on each end, a clamped loop  248  and bushing  66  is approximately 77½″ in length when taut, from the center of one bushing to the center of the other. 
     An actual vehicular impact produces the following energy absorbing actions: 
     1. One or more of the high density polyethylene (HDPE) barrier modules which are impacted, slide, deform from the impact, and finally burst; 
     2. The water in each burst section is released and dispersed over a wide area; 
     3. The cables  246  are engaged and prevent breaching or climbing by the impacting vehicle of the barrier; 
     4. Many modules  210  of the barrier remain assembled together, but are moved during the impact. They are either dragged closer to the point of impact if they are in tension, or pushed away if they are in compression. 
     It should be noted that relatively few barrier modules  210  will burst, depending upon the severity of the impact. Many modules will move and will remain undamaged, with a few having minor leaks which are readily repaired. 
     The bushing  66  serves several advantageous purposes. First, it is a significant contributor to the molding process, making it easier to manufacture and minimizes leaks when the barrier module  210  is completed during the molding process. Also, during impact, the bushing spreads the impact load that is transmitted from the steel cables  246  to the knuckles  218 , and the load is further transferred to the connecting pin  226 . This ensures that the assembled barrier, comprised of a plurality of modules which are joined together, as shown in  FIGS. 7, 8, 12, 13, 18, and 31 , for example, will not be breached during an impact. Moreover, the location of the cables  246  prevents a vehicle from climbing over the wall during an impact. Crash tests conducted on the inventive barrier system demonstrate that the displacement of barrier walls formed of assembled barrier modules  210 , upon vehicular impact, are displaced significantly less than is the case with competing prior art products. This is a considerable advantage, in that clear space required behind the barrier can be substantially less, meaning that less roadway area requires closure. 
     It will also be noted, from review of the figures, that the knuckles  218  of this modified embodiment are differently constructed than those illustrated in the prior embodiments. In particular, in the prior embodiments, the knuckles do not extend substantially the full width of the barrier module. Rather, the outside radius of each knuckle meets a flat surface at the end of the barrier module, and the knuckle only extends about ¾ of the full width of the end wall. The flat surface then extends out to the outer profile of the module, creating the shape of the wall. Under certain conditions, this construction can cause tearing of the knuckles away from the end wall of the barrier module. Accordingly, the knuckles  218  in the embodiment of  FIGS. 35-41  are designed to extend substantially the entire width of the barrier module, as shown, so that the knuckle radius meets the outer, lengthwise walls of the barrier module. This change surprisingly serves to significantly increase the strength of the walls of the barrier module. 
     Another modified embodiment of the inventive concept may comprise barrier modules  210 , molded in 3 foot lengths, with lug connections and cables, as shown and discussed above, for the purpose of functioning as a barricade end treatment. In this embodiment, the T-pins  226  extend downwardly through the connection lugs  218  and bushings  66 , to ground. Such a device comprises a non-gating device, because, with the cable connections, a vehicle cannot get through it. This embodiment may comprise a cast “New Jersey” bather wall, wherein one end is squared off. In this embodiment, female sockets are molded internally on the squared-off end, and sized the same as the male lugs on the other end, so that they fit together for reception of a drop or T-pin. This embodiment results in a flush connection between two adjoining barricade modules  210 , which means there is no surface interruption and no relative rotation between those barrier modules. As noted above, the T-pin extends to ground, and into a hole drilled into the ground, so that there is no wall translation, thus creating the non-gating barrier. 
     It is noted that there is no requirement that the barrier module  210  be ballasted with water. Alternative ballasts, particularly if dispersible, may be utilized. It is also within the scope of the invention, particularly if a particular module  210  is to be used as an end treatment, to fill the module with foam. The foam would be installed during the manufacturing process, and the fill and drain apertures could be eliminated. The cables  246  would still be used. 
     Now, with reference to  FIGS. 44-46 , there is illustrated an array  72  of barrier modules, such as barrier modules  210  shown in  FIGS. 35-41 , connected end-to-end, using pin and lug connections as has been described previously in connection with prior embodiments. However, this array  72  is an end treatment array. End treatment arrays are known in the prior art, and have been briefly discussed above, in conjunction with prior disclosed embodiments. The concept of an end treatment or end treatment array is to secure a crash attenuating device to the front end of a substantially immovable structure, such as a bridge abutment, pillar, or the like, so that an impacting vehicle, rather than crashing directly into the substantially immovable structure, will impact the end treatment array and “ride down” before reaching the immovable structure, thereby protecting the vehicle occupants from serious injury or death. 
     In the present invention, the end treatment array  72  comprises a plurality of barrier modules  210 , secured to one another as shown, and as described above. However, on each end of the array  72  is positioned a transition barrier module  74 . 
     The transition barrier module  74  is illustrated more particularly in  FIGS. 47-50 and 59-62 , for example. In many respects, the transition barrier module  74  is constructed similarly to regular barrier modules  210 , except that it is preferably differently colored, for ready identification. For example, in certain preferred embodiments, the transition barrier module  74  is yellow, while regular barrier modules  210  are orange and white. Additionally, because it is desired that the transition barrier module  74  always be empty, rather than filled with ballast, it may be constructed without a ballast fill hole, and may alternatively or additionally be constructed to have substantial (perhaps approximately 1½ inch diameter) holes near its base to ensure that the hollow barrier module  74  is never filled. 
     A very significant improvement in the inventive end treatment array  72  is the employment of a containment impact sled  76 , shown, for example, in  FIGS. 45-54 . The containment impact sled  76  comprises a frame having side frame members  78 ,  80 , each joined to opposing edges of a front cap  82  and a floor portion  84  ( FIG. 52 ). The frame is preferably made of galvanized steel, having a steel tube frame and sheet metal construction, though other suitable structural materials may also be used. 
     The side frame members  78 ,  80  are each generally triangular in shape, each comprising, respectively, a bottom frame member  86 ,  88 , extending lengthwise along the floor portion  84  from the front cap  82  to the opposing end of the floor portion  84 , a cap end frame member  90 ,  92 , and a top frame member  94 ,  96 . The top frame member  94 ,  96  extends from an upper end of its respective cap end frame member  90 ,  92 , and the front cap  82 , downwardly toward the opposing end of each respective bottom frame member  86 ,  88 , as shown in the drawings. 
     Additional right frame brace members  98 ,  100  and left frame brace members  102 ,  104  are preferably employed to reinforce the strengthen the structural integrity of the containment impact sled  76 . 
     Thus, the containment impact sled  76  is a longitudinal energy disperser which comprises a structure having a defined volume, supported by the floor portion  84  and contained by the side frames  78 ,  80  and front cap  82 . The function of this volume, as will be described below, is to collect and contain debris resultant from the impact of a vehicle with the barrier array  72 , thus preventing that debris from flying about, striking adjacent people, vehicles, and/or structures, or collecting underneath the impacting vehicle and causing that vehicle to ride up over that debris and flip over, or “vault”. 
     As illustrated in  FIGS. 45-50 , for example, the containment impact sled  76  is configured to be attached to one end of a transition barrier module  74 . Attachment is accomplished by sliding the transition barrier module  74  into the sled  76 , so that the barrier module  74  rests on the floor  84  of the sled  76 . The barrier module  74  may be oriented in either direction, so that either end, i.e. the end having five lugs  218  or the end having six lugs  218 , faces the inside surface of the front cap  82 . This capability for dual orientation is shown, for example, in  FIGS. 47-48 and 58 , where the six lug end is secured to the front cap, and in  FIGS. 49-50 and 57 , where the five lug end is secured to the front cap. 
     Once in place, the barrier module  74  is oriented so that a pin hole  106  in the front cap  82  is aligned with the pin holes  224  in each respective lug  218 , as shown. A t-pin  108 , as shown in  FIGS. 55 and 56 , is then disposed through the hole  106  and each lug hole  224  to secure the sled  76  to the barrier module  74 . 
     As noted above in connection with  FIGS. 44-46 , depicting the end treatment array  72 , in addition to the end of the array  72  which includes the sled  76 , there is a second transition barrier module  74  at the opposing end of the array, for the purpose of securing the array  72  to a fixed structural member which the array is positioned to shield from an impacting vehicle, such as a bridge abutment or the like. As is the case with the first transition barrier module  74 , one end of this second transition barrier module is secured to an opposing end of a regular barrier module  210 , as shown. However, the opposing end of this second transition barrier module  74  is fitted with end treatment hardware  410 , which is shown as a set in  FIGS. 63 and 64 . This hardware  410  comprises a left panel  412 , a right panel  414 , a frame  416 , a long pin  418 , two short pins  420 , and a cap panel  422  ( FIG. 60 ). 
     As shown in  FIGS. 59-63 , the end treatment hardware  410  is assembled to the end of the second barrier module  74 . Specifically, the frame  416  comprises horizontal cross-members  424  secured at either end to short vertical hollow hinge posts  426 . The horizontal cross-members  424  each include a pin hole  428 . The frame  416  is assembled to the left and right panels  412 ,  414 , respectively, by assembling the short vertical hollow hinge posts  426  to interleave with respect vertical hollow hinge posts  430  disposed on each of the left and right panels  412 ,  414 , respectively, so that they are aligned. The short pins  420  are then inserted through each of the short vertical hollow hinge posts  426  and  430 , as shown in  FIG. 63 , to thereby secure the frame  416  to each of the left and right panels  412  and  414 . The securement method is such that the panels  412 ,  414  are pivotable relative to the frame  416 , about the axis of each short pin  420 . 
     As shown in the Figures, at the same time the frame  416  is situated so that the pin holes  428  in each horizontal cross-member  424  of the frame  416  are interleaved with, and aligned with the pin holes in the lugs  218  of the barrier module  74 . As shown, the end treatment hardware  410  can be adapted to fit to either the six-lug or five-lug end of the barrier module  74  by appropriately positioning the frame relative to the lugs. Once the holes in the lugs and in the frame cross-members  424  are aligned, the long pin  418  may be inserted through those aligned holes to join the hardware  410  to the barrier module  74 . 
     As shown in  FIGS. 59-62 , the cap panel  422  may be secured with the frame  416  to the barrier module. 
     A significant advantage of the hardware system  410  is that, because of the hinged left and right panels  412 ,  414 , the barrier module  74  may be secured to structures of differing sizes. To complete this attachment, the panels  412 ,  414  are pivoted until the extend rearwardly along the opposed sides of the abutment or other structure, at which time suitable fastening hardware  432  is inserted through the respective holes  434  in each panel to secure the panels respectively to each side of the abutment. 
     In operation, when the end treatment array  72  is impacted by a vehicle, the empty forward barrier module  74  quickly crumples from the impact. The sled, joined to this module as described above, moves rearwardly as the module  74  crumples, scooping up and containing the debris within its volume onto its deck, thus preventing that debris from getting loose and potentially vaulting the vehicle. As the ensuing ballasted modules  210  deform, rupture, and release their ballast, the sled moves rearwardly into the array, scooping up additional deformed and ruptured modules and continuing to contain debris until the vehicle is safely stopped. The inventive system functions as a non-redirective, gating, crash cushion. 
       FIG. 65  is a prior art representation of the way in which reflective nose sheeting is typically applied to the traffic-facing end of a traffic control product, such as the illustrated sled, at a gore point on a roadway. A gore point is a location where traffic separates and may pass either on the left or right side of the traffic control product. A freeway off-ramp presents a typical gore point. Typically, as shown, the sheeting is bolted directly within a fixed metal frame, as shown, with the alternating black and yellow stripes oriented in a particular way. If it is desired to change the orientation of the sheeting, it is necessary to remove the sheeting from the frame, or the entire frame, by unbolting it, and then replacing it with a different piece of sheeting having stripes oriented as desired. 
       FIGS. 66-68  illustrate an innovative approach for applying nose sheeting at a gore point. For example, in  FIG. 66  the same reflective nose sheeting  675  is shown, but it is disposed on a removable panel  670 , instead of within a fixed frame, as in  FIG. 65 . The panel  670  is square with a “square” hole pattern comprising a plurality of fastener holes  676  that allows the panel to bolt to a flat or curved surface. The bolt pattern also allows the panel  675  to be reversible, or to be rotated in 90 degree increments, because of the pattern&#39;s identical orientation on each of the four sides of the square panel. 
       FIG. 67  illustrates the back side  677  of the gore panel  670  shown in  FIG. 66 . This side  677  has angled sheeting that, in the orientation shown, directs traffic to pass on the left. Note that the bolt pattern on the sheet will align with the bolt pattern on the device to which it will be attached. The sheeting orientation on the panel directs traffic to pass on the left side of the device. 
       FIG. 68  illustrates the same panel as shown in  FIG. 67 , but it has been rotated 90 degrees in either a clockwise or counterclockwise direction. Since the bolt pattern is square, it will still align with the bolt pattern on the device to which it will be attached. In this sheeting orientation, vehicles are to pass to the right of the device. 
     This invention is important, because it allows the production of a device that can be placed in any of the three most common roadway situations, and show proper reflective sheeting, just by orienting the panel to match the location. Users do not have to inventory multiple units with fixed sheeting. They do not have to remove permanently affixed sheeting and apply new sheeting for a specific use on the roadway. This is particularly valuable for portable traffic management devices that are frequently re-located to varied applications. The versatility of this portable sheeting panel allows users to avoid having to inventory multiple traffic management units with fixed sheeting in different orientations. This approach is applicable to many different traffic management products. 
     Accordingly, although an exemplary embodiment of the invention has been shown and described, it is to be understood that all the terms used herein are descriptive rather than limiting, and that many changes, modifications, and substitutions may be made by one having ordinary skill in the art without departing from the spirit and scope of the invention.
