Embodiment Construction

[0053] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0054] Such as figure 1 As shown, an autonomous segmented BRT signal priority control method, the method through the real-time response to changes in the travel needs of bus passengers, autonomously modify the BRT signal grouping and priority control scheme, to achieve BRT signal priority control, including the following steps :

[0055] (A) Collect basic information on BRT operation;

[0056] (B) Initialization of segmented bus signal priority scheme;

[0057] (C) real-time modification of the bus signal segmentation scheme;

[0058] (D) Real-time adjustment of BRT operation status scheme;

[0059] (E) Real-time modification of the intersection signal priority control status.

[0060] In the step (A), the collected BRT operation basic information includes three categories: BRT operation static data, historical operation data, and dynamic ...

Abstract

The invention discloses an autonomous sectional type quick bus signal priority control method. The method comprises the following step of through the real-time response of the change of the traveling requirement of bus passengers, autonomously correcting a quick bus signal grouping and priority control scheme, so as to realize the quick bus signal priority control. The method has the advantages that for the running features of a quick bus system, the influence of multiple external factors on the bus signal priority control is fully considered, the priority of the crossed signal of a quick bus is realized in a sectional way through the real-time sensing of the quick bus running states and the autonomous adjustment of a cross signal control scheme, the running efficiency of the quick bus and the traveling efficiency of the passengers are improved, and the unnecessary bus stop and the signal lamp time loss are reduced.

Description

technical field [0001] The invention relates to urban rapid transit operation and intersection signal control technology, in particular to an autonomous segmented rapid transit signal priority control method. Background technique [0002] As an integral part of the modern urban transportation system, urban public transportation plays an important role in the urban transportation system. Many cities in our country have proposed policies and measures to give priority to the development and establishment of advanced public transportation systems. In fact, prioritizing the development of public transport is an important means to adjust the traffic structure and alleviate urban traffic congestion. On the one hand, the public transportation system has the advantages of large carrying capacity, high transportation efficiency, low energy consumption, relatively little pollution, and low transportation cost, making it an important way to alleviate urban traffic problems. On the othe...
