A Pre-signal-based Traffic Flow Method at Immediately Adjacent Dislocation Intersections

Abstract

The invention discloses a pre-signal-based adjacent offset intersection traffic flow passage method. The method is characterized by setting a main road pre-parking line on a reverse lane, wherein themain road pre-parking line is parallel to a reverse lane parking line arranged on the reverse lane and before a T-intersection; dividing a small-flow entrance lane into a left-turn lane and a right-turn lane, wherein the left-turn lane of the small-flow entrance lane is provided with a left-turn stop line; increasing a main road pre-signal light for controlling vehicles to pass or stop at the mainroad pre-parking line, and increasing a small-flow entrance left-turn signal light for controlling the vehicles to pass or stop at the left-turn stop line of the small-flow entrance left-turn lane; and serving the period from start of a green light signal of a main road go-straight signal light to end of a red light signal of a minor road left-turn signal light of the T-intersection as one signalperiod, wherein each signal period is formed by five signal phases. The method has the advantages of fully utilizing available road right of the main road lanes, greatly reducing detouring distance of the left-turning vehicles of the small-flow entrance lane and improving vehicle passage speed.

Description

technical field [0001] The invention relates to a traffic flow method, in particular to a pre-signal-based traffic flow method adjacent to a dislocation intersection. Background technique [0002] With the rapid development of urban construction, the road layout in the city is becoming more and more complex, and there are more and more intersections formed by the intersection of two roads. Two roads intersect to form a cross-shaped intersection or a T-shaped intersection. These intersections are usually provided with traffic lights, and vehicles in different lanes pass in an orderly manner according to the instructions of the traffic lights. [0003] At present, when the gates of some units are located at the top of the T-intersection, a windshield is usually set up at the unit facing the T-intersection for aesthetics and other reasons. In order to ensure that vehicles can enter the unit, there are two openings on the left and right sides of the top of the T-shaped intersec...

AI Technical Summary

Problems solved by technology

When the green signal of the left-turn signal light at the T-shaped intersection is turned on, only vehicles turning left in the forward lane of the T-shaped intersection will pass, and no vehicles will pass in the reverse lane. The signal phase (in one signal cycle, one or several The traffic flow obtains exactly the same signal light color display at any moment, so the continuous and complete signal phase in which they obtain different light colors is called a signal phase) Some lanes on the main road are not fully utilized, and there are idle

Moreover, the detour problem of left-turning vehicles at small-volume entrance roads increases the detour distance and queuing time for vehicles, which reduces their traffic efficiency and intensifies the evacuation pressure downstream of the T-shaped intersection.
