Abstract

The invention discloses a quick bus signal priority cooperative control method of primary and secondary crossings, and is applied to a BRT (Bus Rapid Transit) system. The method comprises the steps that a plurality of detectors are arranged at setting positions of primary crossings for predicting the arrival time of buses in advance, the corresponding signal phase lengths of the crossings are adjusted in proportion, and the signal lamps of the crossings are controlled; and simultaneously, for the secondary crossings, the bus stop delay is converted into a space length, and cooperative control is carried out by amending the space distance in a path section and calculating green time difference. The method overcomes the disadvantage that a traditional signal priority control method does not consider crossing cooperation, and the total traffic efficiency of main line can be enabled to be optimal.

Description

technical field

[0001] The invention belongs to the technical field of bus signal control, is used in a BRT system of a bus rapid transit, and relates to a signal priority cooperative control method of a primary and secondary intersection used in a bus rapid transit. 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 development of social economy, urban traffic problems are becoming more and more prominent, and gradually become an important factor hindering the development of social economy. Vigorously developing public transportation is a powerful means to solve urban traffic problems, and providing signal priority for public transportation is also a technical means to improve the efficiency of public transportation.

[0003] In the existing BRT system, due to the establishment of bus-only lanes, the delay of buses on road sections can be ignored; how...
