Embodiment

[0050] Taking an intersection as an example, further detailed description will be given in conjunction with the accompanying drawings and Table 2.

[0051] This level road intersection system is formed by two mutually perpendicular two-way four-lane intersections. Each intersection is equipped with left-turn lights and straight lights. Go straight and turn right; there is also a left-turn guiding channel at this intersection, and its entrance is 30 meters away from the stop line; a left-turn waiting area is set in the opposite right lane of the intersection on the same side, and the left-turn guiding channel is the same as the left-turn waiting area. Turn area connection; left-turn stop line and left-turn traffic lights are set at the entrance of the left-turn guide passage.

[0052] Assume that the traffic mode of the intersection system takes 240 seconds as a cycle. This cycle time can vary depending on the traffic conditions at each intersection. Figure 1-Figure 6 It is ...

Abstract

The invention discloses a plane road intersection dispersion system without a left turn conflict. A left turn guiding channel having a certain distance from stopping lines is arranged at a left-most lane in any driving direction of an intersection, a left turn waiting zone is arranged at an right-most lane of an inverted road of the same intersection, and the left turn guiding channel and the left turn waiting zone are connected. Left moving stopping lines and left moving traffic lights are arranged at the entrance of the left turn guiding channel. By utilizing the idle time that no vehicles are on the inverted road when the straight driving direction is in a red light period, left-turning vehicles are enabled to stop at the right-most side of the inverted lane, left turning is finished by one time during the red light period of the intersection, and no conflicts are generated between opposite vehicles. According to the invention, the smooth passing requirements of the straight-driving and left-turning vehicles are satisfied, the crossing conflicts and accidents of vehicles are reduced, and the vehicle passing capacity of the intersection is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of urban road traffic planning and traffic control, and specifically relates to a left-turn conflict-free level road intersection guidance system, which can reduce vehicle intersection conflicts and accidents, and can effectively improve the vehicle traffic capacity of the intersection. Background technique [0002] At present, the urban traffic is becoming more and more congested, and the intersection is the bottleneck area for the dredging of the entire urban road network. Therefore, the key to solving urban traffic problems lies in regulating and dredging the traffic situation at the intersection. In the convective conflict at the intersection, the left-turn traffic flow and the opposite through-going traffic flow and the flow of people occupy the majority. If the problem of left-turn traffic flow at the intersection can be reasonably solved, the traffic safety at the intersection and the traffic efficienc...
