Embodiment Construction

[0038] see figure 1 As shown, it is an early-rising and early-falling traffic control method suitable for flat peak or low peak hours according to an embodiment of the present invention. In terms of extinguishing time, specifically, the straight green light is turned on earlier than the left turn green light, and when it is turned off, the straight green light is turned off earlier than the left turn green light; it includes the following steps:

[0039] S1: Control the straight-going green light to light up for the first predetermined time t1; at this time, the straight-going vehicle waiting at the intersection passes through smoothly, and at the same time, the turning vehicle travels to the turning waiting area.

[0040] S2: After the straight green light is lit for the first predetermined time t1, control the straight green light and the turning green light to light the second predetermined time t2 at the same time; at this time, the traffic lights are equivalent to being i...

Abstract

The invention relates to an early-on early-off traffic control method and system applicable to average periods or bottom periods. Going-straight green lights are turned on firstly for first preset time t1, the going-straight green lights and turning green lights are turned on simultaneously for second preset time t2, and the going-straight green lights are turned off while the turning green lights are turned on for third preset time t3. Going-straight vehicles are guaranteed to pass firstly in the first preset time t1, and the condition that going-straight is held by turning when the green lights for turning and going-straight are on simultaneously is prevented; in the second preset time t2, going-straight and turning vehicles proceed simultaneously and pass alternately at safe intervals, so that the vehicles driving in during the average periods or the bottom periods can pass intersections as quickly as possible; in the third preset time t3, way clearing protection time for turning vehicles stopping in regions for turning to pull away crossings safely is left, so that passing of following vehicles in other directions is facilitated. According to the method and the system, a gap acceptance theory is fully used, so that the intersection passing efficiency of the vehicles in all directions is improved, and the traveling efficiency and the traveling safety in the average periods or bottom periods are guaranteed.

Description

technical field [0001] The traffic control method of the present invention is specifically a traffic control method and system for early rise and early fall applicable to flat peak or low peak hours. Background technique [0002] Reasonable traffic organization is an important part of Intelligent Transportation System (ITS), which is based on the premise of frequent changes in traffic flow in all directions at intersections during flat peak or low peak hours, and a large distance between vehicles. During flat peak and low peak hours, the traffic flow at the intersection is very unstable, and the loss of passing the green light according to the phase is large, and the traffic efficiency of the intersection is reduced. If the vehicle clearance is organized according to the two-phase (full-screen light) clearance method commonly used at present, the traffic order will be relatively chaotic. , the straight-going and right-turning green lights are on at the same time) are on at ...
