Intersection multiline public traffic vehicle priority request conflict coordination control method

Abstract

The invention discloses an intersection multiline public traffic vehicle priority request conflict coordination control method. By aiming at an intersection with the multiline public traffic vehicle priority request conflict and comprehensively considering factors such as travel time delay of vehicles, priority strategies and the road grade, a real-time multiline priority request conflict coordination control strategy is established. Only when travel time delay of one public traffic vehicle exceeds a certain threshold value, a priority request meets the limiting condition and the benefit brought by priority is higher than delay caused by the priority, the public traffic vehicle sends a priority request signal; when a multiline priority request is generated, a priority level evaluation model is utilized to sort conflicted priority requests, and the priority of passing is given to a line with the highest priority level. On one hand, the problem of unfairness of an original multiline priority request conflict solution is solved; on the other hand, parameters which the method relates to are fewer and are very easy to obtain, a complex algorithm, an optimizing process and the like are not required, practicality is high, and operating efficiency of an urban public traffic system can be greatly improved.

Description

technical field [0001] The invention relates to the field of traffic management and control, and in particular to a method for priority request conflict coordination control of multi-line bus vehicles at intersections. Background technique [0002] Waiting time at intersections is a major component of travel time delays during bus operations. Therefore, if the waiting time of buses at intersections is reduced, the service quality of buses, including travel time and punctual reliability, will be greatly improved. The bus signal priority system allows the bus to pass at the intersection first, so it has been recognized as an effective measure to reduce the delay of the bus intersection. [0003] Most of the existing bus priority control methods focus on one-way traffic or only study a few bus lines, which are quite different from the actual situation. If there are many lines running in multiple directions, the existing research results not only cannot guide bus operation wel...
