Embodiment Construction

[0025] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0026] Such as Figure 1 to Figure 3 As shown, a conflict-free two-phase signalized intersection includes four traffic lanes 2 and a crossing 1, and each fork of the crossing 1 is connected to a traffic lane 2;

[0027] The four traffic lanes 2 are respectively the first traffic lane 21, the second traffic lane 22, the third traffic lane 23 and the fourth traffic lane 24, and each of the traffic lanes 2 includes an entrance road 231 and an exit road 232, so The entrance road 231 is placed on the side of the exit road 232. The entrance road 231 includes a left-turn waiting area 233 and a straight lane 235. The left-turn waiting area 233 is placed near the exit road 232 and near the intersection 1. One end, the strai...

Abstract

The invention relates to a conflict-free two-phase signal intersection which comprises running lanes and a crossroad which are connected. Compared with the prior art, the problem of a crossing conflict between a left-turning vehicle running in an allowable phase and a coming straight-running vehicle is solved through canalized traffic stream division, and conflict points are eliminated, so that vehicle running is safe, smooth and high in efficiency.

Description

technical field [0001] The invention relates to the field of urban road micro-traffic, in particular to a conflict-free two-phase signal intersection. Background technique [0002] Two-phase signal control is widely used in urban road intersections with small traffic volumes. Its signal cycle is short, the number of clearings is small, the green signal ratio reaches 0.45, and the traffic efficiency is high. The size is very sensitive. The traffic flow is small in the off-peak period, and the conflict is adjustable, which is not a big problem. However, when the traffic flow increases in the morning and evening peak hours, it may turn into a complete conflict, making the vehicle traffic neither safe nor smooth. , avoidance leads to delays, the most serious can cause traffic jams and even cause traffic accidents. In order to avoid this situation, the method of multi-phase or left-hand ban is currently used to organize left-turning traffic flow to solve the problem of crossing ...
