TRAFFIC SIGNAL CONTROL SYSTEM, DESIGN METHOD AND SPECIAL EQUIPMENT

摘要

FIELD: physics.SUBSTANCE: method involves determining the shortest green light interval; confirming the conflict area of the other traffic flow and the key conflict point position according to the engineering design for road routing; determining the longest distance s(m) between the last vehicle falling in the interval of the green light i and the shortest entry distance s(m) of the traffic head unit of green light j and the blinking green light i; calculating the longest clear time Max{t} of the last vehicle of green light i and the shortest entry time Min{t} of the first vehicle of green light j; calculating the shortest green light interval; confirming the control scheme for the crossing according to the shortest green light interval and sending the control instruction to the traffic signal display device for displaying in real time according to the control scheme.EFFECT: higher crossing throughput.14 cl, 5 tbl, 9 dwg
