Abstract:
A portable template for making scale drawings of traffic intersections where first and second streets meet, the drawings comprising at least two curblines, each curbline comprising first and second segments corresponding to intersecting street edges and connected by an arc of a predetermined radius corresponding to a corner of the intersection to be drawn, said template comprising:first and second intersecting legs comprising first and second perpendicular inner edges enabling the drawing of the curblines, one leg inner edge enabling the drawing of the first segment of each curbline to be drawn and the other leg inner edge enabling the drawing of the second segment of each curbline to be drawn, the second segment of each curbline being perpendicular to the first segment thereof; at least one curved portion enabling the smooth drawing of said arcs between said first and second segments of each curbline; wherein the first leg comprises a first calibrated projecting slot extending across it in axial alignment with the inner edge of the second leg, and the second leg comprises a second calibrated projecting slot extending across it in axial alignment with the inner edge of the first leg, said first leg having a calibrated dimensioning slot extending across it at a location between the first calibrated projecting slot and the free end of the first leg, said second leg having a calibrated dimensioning slot extending across it at a location between the second calibrated projecting slot and the free end of the second leg, said projecting and dimensioning slots for establishing reference drawing points to which the leg edges may be thereafter fitted for proportionally drawing subsequent curblines; and a plurality of curved outer corners; and a plurality of cutouts defined in the template to be used as a guide for drawing traffic symbols, road markers, road signs, obstacles, and vehicles.
