Cooperative control method of left-opened-door bus special phase setting and social traffic flow

Abstract

The invention discloses a cooperative control method of a left-opened-door bus special phase setting and social traffic flow, which comprises the following steps: setting a bus station and a stereo facility which help pedestrians to cross a street; detecting a bus; determining the running time of the bus; determining a signal phase of the bus which drives through an intersection; and setting the bus special phase and a cooperative control plan. According to the invention, the bus stations in two directions are combined and placed at a median strip of the intersection, so that not only the land is saved, but also the bus station points are easier to recognize, and meanwhile, a new concept for planning and constructing of a public transit network is provided, that is, the public transit network is connected based on the bus stations arranged at intersections. With the adoption of the method, the situation that the bus does not stop at an intersection without a bus station while stops at an intersection with a bus station can be basically realized, so that passengers waiting for a long time at an intersection with a bus station can be avoided, thereby shortening the whole driving time of the bus and improving the whole operation efficiency of the bus system. Moreover, the method is functioned as the cooperation of the social traffic flow, so that the passing efficiency of the whole intersections is guaranteed.

Description

Technical field [0001] The present invention relates to the field of urban public transportation systems. It is suitable for urban conventional public transportation systems equipped with bus lanes. The main goal is to set up left-opening two-way shared platforms at intersections and add bus dedicated signals to the original control plan. Phase, significantly reduce the delay of buses at intersections, and realize the coordinated control of buses and other social vehicles. Background technique [0002] Urban public transportation is an important part of the urban integrated transportation system and the main body of urban passenger transportation. The conventional public transportation system is the most common form of urban public transportation. It includes three levels: network, line, and node. At the route level, in order to fully ensure the efficiency of public transportation, many urban public transportation systems have dedicated bus lanes to separate buses from other vehi...

Problems solved by technology

With the development of urban modernization, traffic control technology at intersections tends to be enriched and perfected. However, the inherent weaknesses of traffic control technology, such as additional delays, also restrict the transport efficiency of urban public transport systems. For this reason, people put forward Some bus priority control measures at intersections, such as extended green lights, early breaks of red lights, phase insertion, pre-signal control, etc., are used to reduce the delay of buses at intersections. It reduces the large time loss of social vehicles, and also increases the complexity of signal control

For example, the phase insertion measures require all social traffic in a phase to give way to buses, which will obviously increase the overall delay level of the intersection
