Green wave signal control method in bus system area

Abstract

The invention discloses a green wave signal control method in a bus system area. The green wave signal control method in the bus system area comprises the steps of: firstly, dividing routes in the area into transverse routes and lengthways routes; then calculating a regular timing scheme by using a Webster signal timing method; determining a key period based on an average delay time which is taken by a bus to stop at bus stops for loading and unloading passengers and an average time length which is taken for passing through crossings; converting the delay time to a spatial distance; determining a virtual road network and gridding the area; alternately arranging transverse periods and lengthways periods of each grid cell; adjusting signals by using a mathematic solution way to guarantee bus green waves; and finally determining a first bus time, a last bus time and a departure interval based on a signal period and a change rule. Through signal coordination control and bus scheduling in the area, the control method provided by the invention, has the advantages of guaranteeing bus green wave passing in the whole region, reducing delay of the bus system and improving service level of the bus system.

Description

technical field [0001] The invention relates to urban road traffic control technology, in particular to a regional green wave signal control method of the public transport system that ensures the green wave traffic of the entire area, reduces the delay of the public transport system, and improves the service level of the public transport system through the coordinated control of regional signals and public transport dispatching . Background technique [0002] With the rapid development of the urban economy and the continuous expansion of the population, public transportation as a large transport capacity has become more and more popular. However, the existing public transportation system is restricted by roads, signals, dispatching modes, etc., and its operating efficiency is not high. The concept of public transportation green wave came into being. [0003] The connotation of the bus green wave is: during the driving process of the bus, there is almost no other parking exc...

Problems solved by technology

Existing technologies and patents mostly stay at the single-line control level, it is difficult to form an effective area signal priority, and little consideration is given to the diverted bus lines
