Method for setting bidirectional green wave signals for bus trunk line

Abstract

The invention discloses a method for setting bidirectional green wave signals for a bus trunk line. According to the method for setting the green wave signals, each signal lamp at an intersection is coordinated and controlled, the bus departure moment is adjusted by matching dispatching of a bus, and an optimal green wave signal set method for an urban bus system is calculated and acquired by adopting a corrected numerical solving method. By the method, the influence of green wave signal control at the intersection on the running efficiency of the bus system is fully considered; and buses quickly pass through the intersections in green wave by adjusting the signal phase difference between the intersections of the trunk and the departure time table of the urban buses. The method is convenient to calculate and strong in practicability, can greatly improve the operating efficiency of the urban bus system and bring great convenience to outgoing of urban residents, and has significance for improving the current situation of the urban buses.

Description

technical field [0001] The invention relates to urban public transport planning and intersection signal control technology, in particular to a method for setting bidirectional green wave signals of a main bus line. Background technique [0002] As an integral part of the modern urban traffic system, urban public transport occupies a pivotal position in the urban traffic system. With the rapid development of social economy, increasingly fierce competition, and the accelerating pace of life, people's demand for transportation is also increasing, and the trend of motorized travel is becoming increasingly prominent. At present, traffic problems such as urban traffic congestion have become the main bottleneck restricting the sustainable development of cities, aggravating the deterioration of urban life quality, and causing major losses in terms of economy, safety and environment. Prioritizing the development of urban public transport systems has become an important means to alle...

AI Technical Summary

Problems solved by technology

[0003] At present, in the existing urban public transport system, due to the unreasonable coordination and control of the intersection signal timing scheme and the main road signal, as well as the problems in the design of lanes and the setting of bus stops, a large amount of signal time is wasted, which seriously hinders It hinders the construction and priority development of the advanced urban public transport system, reduces people's travel efficiency, and makes the modern urban public transport system fail to exert its greatest advantages

Especially in the layered construction and hierarchical operation of urban public transport, although most cities have proposed the concept of public transport layering and grading for the trunk line, secondary trunk line, and branch line, but in the specific construction and operation implementation stages, it plays an important role. The main bus line has not received the greatest and most attention, and lacks the inclination of road space-time resource supply
