DETERMINING THE LENGTH OF THE APPROACH LANES REQUIRED AT SIGNAL-CONTROLLED INTERSECTIONS ON THROUGH HIGHWAYS

THIS PAPER IS BASED ON THE WAVE THEORY PUT FORWARD BY LIGHTHILL AND WHITHAM (1955) AND IS CONCERNED WITH THE BRAKING OF A FLOW OF MOTOR CARS AS A RESULT OF A SHOCK WAVE WHICH, AT THE BEGINNING OF THE RED PERIOD, MOVES FROM THE STOP LINE BACKWARDS ALONG THE ROAD AGAINST THE INCOMING TRAFFIC, REDUCING THE SPEED OF THE LATTER. IT IS SUGGESTED THAT THE LENGTH OF THE QUEUE SHOULD BE DEFINED BY THAT PART OF THE INCOMING TRAFFIC WHICH IS AFFECTED BY THE SHOCK WAVES. ON THIS BASIS, A METHOD IS PROPOSED FOR DETERMINING THE LENGTH OF THE APPROACH LANES REQUIRED. /AUTHOR/
