Lane setting at road intersection and corresponding traffic light control method

Abstract

A lane setting at a road intersection and a corresponding traffic light control method. It does not distinguish between primary and secondary roads, so that the number of entrance and exit lanes of each main phase is kept equal; the entrance lanes are divided into three parts: "entrance guide lane", "peripheral guide lane" and "bus and right-turn lane"; according to the direction of travel Arrange the lanes, light groups, signal groups and phases symmetrically on the horizontal axis of the horizontal axis; at the intersection, run the main phase of A going straight——B going straight——A turning left (including U-turn)——B turning left (including U-turn); The "peripheral traffic lights" alternately operate the two phases of straight-going vehicles moving forward and left-turning (including U-turn) vehicles moving forward, and an evergreen phase and "electronic police" for directing right-turning vehicles and buses to pass; according to the number of left-turning vehicles Decide whether to control the clearance of pedestrian crossings in units of full or half-way. This method can make the number of lanes passing by each phase of the intersection reach the maximum on the basis of equilibrium, and is conducive to the priority of public transportation and the convenience of pedestrians.

Description

Technical field: [0001] The invention relates to a lane setting of a road level intersection and a corresponding traffic light control method. It belongs to the discipline of traffic engineering. Background technique: [0002] Because the vehicles released by each phase can only use the road space of the level intersection in turn, the level intersection has become the main bottleneck restricting the road traffic capacity. At present, the known lane setting at intersections and the release of vehicles mainly follow the space separation method and the time separation method. That is: Let the vehicles before entering the intersection enter the guide lane according to U-turn, turn left, go straight, bus, and turn right, and let them pass the intersection at the specified time and space respectively based on the principle of no conflict. In order to adapt to the growth of traffic demand, when designing (including newly built and rebuilt) intersections, measures such as left-se...

Problems solved by technology

For example: although there are many guide lanes entering the intersection, when it is the turn of a specific phase to pass, the corresponding guide lanes are still not enough, or, even if there are enough entrance guide lanes for each phase, its corresponding exit There are not enough lanes. Their essence is that the traffic flow that is allowed does not use up the space in the center of the intersection.
