Problems solved by technology

[0004] At present, when the tram passes through the intersection, the green light method for controlling the intersection to open the tram is based on the fact that the tram departure interval is equal to the cycle or an integer multiple of the cycle, which is difficult to apply in the actual engineering, making the current Inefficient tram traffic

Embodiment Construction

[0044] In order to make the objectives, technical solutions and advantages of the present application more clear, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

[0045]In one embodiment, as figure 1 As shown, a method for priority control of intersection signals based on the departure interval of trams is provided, including the following steps:

[0046] Step S220: Acquire signal control data on the target line whose departure interval determined in advance by analysis and the intersection signal control period is not an integral multiple of the intersection signal control period.

[0047] Step S240: Control the intersection signal of the intersection on the target line according to the signal control data, so that when the tram on the ...

Abstract

The present application relates to a priority control method for intersection signals based on tram departure intervals. The method includes: acquiring signal control data in which the pre-analyzed and determined departure interval on the target line is not an integer multiple of the intersection signal control period, and the signal control data includes that all intersections on the route need to turn on the green lights in advance or prolong At the moment, according to the signal control data, the intersection signal of the intersection on the target line is controlled, so that when the tram on the target line arrives at the intersection on the line, the green light is turned on first, and the line is accurately controlled. The timing and duration of priority control at intersections, thereby improving the efficiency of tram traffic.

Description

technical field [0001] The present application relates to the technical field of signal control, and in particular, to a method for priority control of signals at intersections based on the departure interval of trams. Background technique [0002] With the development of tram signaling technology, tram green wave and tram priority control technology have been widely used. By controlling the green light to turn on the traffic when the tram passes through the intersection, it can effectively reduce tram parking. Wait times to increase traffic efficiency. [0003] When the tram passes through the intersection, the green light method to control the intersection to open the tram to pass is based on the tram departure interval being an integer of the intersection signal control period, but in practical engineering applications, there will be rail cars If the departure interval of trams is not an integral multiple of the cycle, the time at which the tram arrives at the intersecti...
