A joint optimization method of connected bus signal coordination and speed guidance considering multiple bus requests conflicts

By grouping and coordinating bus routes and constructing a green wave coordination model, the problem of conflicting signal priority requests from multiple buses at intersections was resolved, improving the priority efficiency of buses and the continuity of green wave coordination, and reducing the impact on private vehicles and buses on other routes.

AI Technical Summary

Technical Problem

Existing technologies fail to effectively resolve signal priority request conflicts when multiple buses arrive at an intersection at the same time, resulting in low bus priority efficiency. They neglect the contradictions between green wave coordination, speed guidance, and bus signal priority strategies, and do not fully consider the impact of green wave bandwidth in the bus corridor and other bus routes.

Method used

By establishing a joint optimization method for green wave coordination and speed guidance, bus routes are coordinated in groups, a green wave coordination target model is constructed, and it is assessed whether buses can pass through the green wave or need to apply for signal priority. When conflicts exist, bus signal coordination and speed guidance are optimized, taking into account the impact of delays of private vehicles, to achieve optimized bus operation without conflicts.

Benefits of technology

It improves the priority efficiency of buses, reduces the impact on buses on other routes and other vehicles, and achieves joint optimization of bus signal coordination and speed guidance under multiple vehicle request conflicts.

Abstract

The application discloses a kind of considering multiple vehicle request conflict's network connection bus signal coordination and speed guidance combined optimization method, the method includes on the basis of actual operation of bus, complete bus priority multi-strategy optimization model is established, considering bus signal priority application conflict, multi-strategy bus operation optimization process is described by system, the delay of considering social vehicle and bus vehicle, to guide the actual driving behavior of bus and intersection signal optimization;On this basis, guide bus to run on bus lane, reduce the time of parking and waiting, improve bus priority efficiency, form a kind of bus signal coordination and speed guidance combined optimization method, to realize the organic combination of bus priority signal-speed guidance-trunk coordination strategy.The application solves the long parking and waiting time caused by the difficulty in processing existing intelligent network connection bus signal priority application conflict, a series of public transport inefficiency problems such as delay of arrival time.
