Embodiment Construction

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

[0054] like figure 1 Shown is a flow chart of a method for site location optimization based on priority coordinated control of public transport signals according to the present invention:

[0055] (1) Set up bus green waves on the main bus road to achieve coordinated control between multiple intersections;

[0056] Specifically, step (1) includes:

[0057] (11) Use the bus station as a node to segment the implementation road section to determine whether the green wave implementation conditions are met. When the number of intersections between adjacent bus stations is not less than 2, the implementation of green wave signal control between bus stations can be considered; Otherwise, end this process;

[0058] (12) To set the bus green wave front, first, according to the traffic flow ratio and the loss time per cycle of each intersection of the ...

Abstract

The invention discloses a station position optimization method based on bus signal priority coordination control. The optimal bus operation efficiency acts as the goal. Firstly, trunk line intersections are grouped with bus stations acting as nodes, green waves between the bus stations are set in the intersection groups and coordination control is performed on the vehicles of the bus trunk line; then whether a bus signal priority strategy is started is judged according to stop line arrival time of the buses; then the influence of the stations of different positions on the operation efficiency of the buses is analyzed when the bus signal priority is performed; and finally the bus station position optimization scheme under different road conditions is put forward according to the analysis result so that the implementation effect of bus priority coordination control can be enhanced, and thus the operation effectiveness and the service level of the buses can be enhanced.

Description

technical field [0001] The invention belongs to the field of urban public transport facility planning and management, and relates to a bus stop position optimization technology, in particular to a station position optimization method based on priority coordinated control of bus signals. Background technique [0002] As the most basic urban public transport facilities, bus stops are the link between passengers and public transport services, and are an indispensable part of the public transport system to achieve its services. At present, large cities in my country have dozens to hundreds of bus lines. According to the average number of 20 stops per line and the repetition coefficient of 2.5, each city has at least thousands of bus stops. Therefore, the rationality of the layout design of urban bus stops has an extremely important impact on the overall operation of urban traffic and urban construction. However, in practice, the planning and design of urban bus stops in my coun...
