Embodiment Construction

[0055] The present invention will be further described below in conjunction with embodiment and accompanying drawing.

[0056] Such as figure 1 As shown, the priority control method for multi-line multi-bus vehicles at signalized intersections of the present invention performs steps 10) to 60) for each bus vehicle in a signal phase in turn according to the order of arrival, to determine whether the control center receives the bus vehicle Priority request, until a signal phase expires, the control center updates the signal timing according to the received priority request, generates a priority phase and executes it. The method specifically includes the following steps:

[0057] Step 10) if it is detected that the bus vehicle arrives, according to the bus vehicle running state data collected by investigation, utilize the artificial neural network model to predict the bus arrival stop line time;

[0058] Described step 10) specifically comprises the following steps:

[0059] S...

Abstract

The invention discloses a multi-line multi-public transport vehicle priority control method at a signal intersection. Aiming at the condition that a multi-line multi-public transport vehicle priority request collision problem at the signal intersection of a trunk line is increasingly prominent at present and the control effect of the present method is bad, the method selects two indexes of public transport passenger delay and passenger waiting delay at a downstream bus station to measure priority levels of the multiple priority requests. Then the delay corresponding to the multiple public transport vehicles of multiple lines applying for the same priority strategy is added. The priority level corresponding to the priority request with the large delay is high, and a higher passing priority is given. Thus the multi-priority request collision problem is solved. The control efficiency of the public transport priority is raised. The service level and the operation efficiency of the city public transport are improved. More passengers are attracted.

Description

technical field [0001] The invention belongs to the field of public traffic signal control of urban traffic, and relates to a multi-line multi-bus priority control method at a signalized intersection. Background technique [0002] The transportation topic of the "National Medium- and Long-Term Science and Technology Development Plan" clearly puts forward the national strategic goals of "solving urban traffic congestion by giving priority to the development of public transportation" and "reaching more than 50% of public transportation in large cities". With the introduction and advancement of the concept of "transit city", most cities across the country have begun to invest heavily in the development of public transport. After several years of development, many cities in my country have gradually formed a multi-mode and multi-level public transportation structure, and the complexity of the public transportation network has also continued to increase, which makes the possibili...
