Traffic Organization and Design of Left-turn Forbidden Traffic Flow on Signalized Intersections
摘要
Abstract
Reasonable organization of left-turn forbidden traffic flow could effectively reduce the left-turn vehicles delay through signalized intersection.There are barriers between two-direction vehicles,through the queuing and probability theory,the distance of two indirect left-turn modes from the road turn-around position to the intersection stop line was studied.To "right-turn,turn-around and through" mode,considering coordination-control or not for right-turn signal and intersecting-road through signal,the distance calculation model was established.To "through,turn-around and right-turn" mode,taking the two condition weather setting road median-opening signal to coordinate intersection signal into account,the distance calculation model was obtained too.To the "through,turn-around and right-turn" mode,when the coordination-control policy was adopted,the technique of "early-startup and early-stop" of road median-opening signal was put forward,and the calculation method of the time of "early-startup and early-stop" was put forward as well.The case study indicated that the indirect left-turn organization scheme was feasible,and had obvious effect on improving the operation of the signalized intersections.关键词
