Intersection traffic control method based on tramcar active operation control system

Abstract

The invention discloses an intersection traffic control method based on a tramcar active operation control system. The control system comprises an information acquisition module, a processing module and a publishing module. The control method comprises the following steps of starting the guiding process, and judging whether a tramcar enters a control area or not based on tramcar running data; based on tramcar running data, signal timing data and road data, judging the signal state of the tramcar which is running to a downstream intersection; according to the result of the previous step, correcting the reasonable running speed of the tramcar; judging whether a calculation result meets the condition or not; sending the calculation result to a corresponding tramcar by means of the publishing module to adjust the running speed of the tramcar; and controlling the tramcar to pass through the intersection. According to the technical scheme of the invention, the dynamically optimized running speed prompt information is provided for the driver of the tramcar by means of a tramcar-mounted display terminal. Therefore, on the premise that other vehicles on the road are not influenced at all, the tramcar is enabled to pass through the intersection in the green-wave manner.

Description

technical field [0001] The invention relates to the technical field of trams, in particular to an intersection traffic control method based on a tram active operation control system. Background technique [0002] Trams generally run on urban roads, and are a kind of rail transportation that is easily affected by other urban road traffic facilities. They are often laid on the main roads of old cities or new cities with dense passenger flows, and they will inevitably be affected by ground signals during driving. Intersection restrictions reduce its operating efficiency and affect travel speed. [0003] During urban road driving, the tram cannot obtain real-time information on the status of the signal lights at the intersection ahead, so the driver cannot judge the status of the signal lights when the tram arrives at the downstream intersection, and can only rely on the driver's experience to determine the driving status and speed , thereby improving the possibility of "eating...

Problems solved by technology

[0002] Trams generally run on urban roads, and are a kind of rail transportation that is easily affected by other urban road traffic facilities. They are often laid on the main roads of old cities or new cities with dense passenger flows, and they will inevitably be affected by ground signals during driving. Intersection restrictions reduce its operating efficiency and affect travel speed

[0003] During urban road driving, the tram cannot obtain real-time information on the status of the signal lights at the intersection ahead, so the driver cannot judge the status of the signal lights when the tram arrives at the downstream intersection, and can only rely on the driver's experience to determine the driving status and speed , thus increasing the possibility of "eating the red light" when the tram reaches the stop line at the intersection, and increasing the "stopping opportunity" and waiting delay of the tram at the intersection

On the other hand, if priority is given to intersection signals to improve the traffic efficiency of trams and reduce parking, then it is necessary to sacrifice a certain amount of time for social vehicles in other entrance directions, which will have a certain impact on the balance of phase timing of intersection signals
