Title: Improvements in or relating to Traffic Control Systems
IPC: G08G1/081
Filed: 1967-04-13
Abstract: 1,187,054. Road signals for controlling traffic. SUMITOMO ELECTRIC INDUSTRIES Ltd. 13 April, 1967 [15 April, 1966], No. 16976/67. Heading G4Q. In a road traffic control system for a district D having a plurality of road sections each being terminated by intersection signals, an offset effect value, which is defined as the difference between the mean and minimum values of traffic delay time of a road section over the entire range of relative offset value from 0 to 1 for a section, is calculated for all the road sections in the district and the road sections having the largest, second largest, third largest and so on offset effect values excluding any section which would form a closed road loop are selected until one tree of sections is formed and offset values are given to all the sections forming the tree to minimize the traffic delay along the tree and control of the district is effected by a district controller DC-2D sending information of offset, cycle and split values to local controllers LC controlling signals located at all intersections along the tree. Examples of tree formations are shown in Figs. 5a and 5b. The tree is determined as above by the offset effect values of all the sections at a predetermined time interval. The relative offset for the lights at the ends of each section may be determined from a flow chart (Fig. 6, not shown), by comparison of the traffic flow q, q<SP>1</SP> in opposite directions with a constant value qo for that road section. Depending on this comparison either preferential offset or balanced offset of the simultaneous or alternating type is employed to minimize the total delay time along the tree. The traffic conditions may be detected by electromagnetic or photo-electric detectors which feed signals to the district controller DC or a control controller CC. In further districts A, B, C, where no closed road loops occur a class 1 district controller DC-1 controls the signals so as to provide optimum cycle length, split and offset. The cycle length is determined by the maximum traffic counted in that district and the split is determined by the traffic volume flowing into each intersection. The offset value is determined by the method indicated above obtained from the flow chart (Fig. 6, not shown). Also the determination of the cycle length and split for the class 2 district controller DC-2 is obtained in the same way as that for the class 1 district controller DC-1, All the district controllers may be controlled by the common central controller CC which co-ordinates the district controllers by giving cycle value or values common to a group or groups of district controllers. Also the central controller gives offset values to a road section or sections which connect adjacent districts to minimize delay time in both directions.
