Problems solved by technology
[0003] However, due to the non-closed right-of-way of trams, especially at public intersections, the sharing of right-of-way with passenger cars and pedestrians, the lower operating speed and efficiency of trams are closely related to the passing priority of intersections.

Embodiment Construction
[0023] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0024] Such as figure 1 Shown is a tram cooperative control method based on active driving control, the steps of the control method are:
[0025] S1. First, the tram sends a signal to the traffic signal light to determine whether it is an intersection passed by a tram. If not, it means that the intersection is not a crossing passed by a tram. Then there is no need to control the traffic signal light to maintain its normal operation. Yes, if it indicates that the intersection is an intersection that trams need to pass through, then go to step S2.
[0026] S2, judging whether the intersection is a red light, if it indicates that the traffic signal light at the intersection is in a red state, then enter step S3, if not, it indicates that the traffic signal light at this intersection is in a green or yellow state, then enter step S4.
[0027] S3. Determine whether the ...

The present invention relates to a coordinated control method for trams based on active driving control. S1, judge whether it is a crossing where a tram passes, if otherwise, it is running normally, and if so, go to S2; S2, judge whether the crossing is a red light, if so, then Enter S3, if otherwise, enter S4; S3, judge whether the time to reach the intersection is greater than the time of the red light + 3s, if so, pass the intersection, if otherwise, stop at the intersection; S4, judge whether the time to pass the intersection is less than the time for the green light, if so, pass the intersection, If otherwise, go to S5; S5, judge whether the time to pass the intersection is less than 1.5 times the green light time, if so, extend the green light to pass normally, if otherwise slow down and enter S6; S6, judge whether the time to slow down to 3km / h is less than the green light time and the next The sum of the red light time, if yes, slow down and pass, otherwise stop to the intersection. Improve the efficiency of operation and reduce the occurrence of safety accidents.
Description
technical field [0001] The invention relates to the technical field of automatic driving of rail transit trams, in particular to a method and system for coordinated communication control between vehicles and ground crossings. Background technique [0002] With the large-scale operation of subways in big cities, the demand for large-scale transportation has been solved. However, for residential areas not along the subway lines, it is necessary to solve the connection with the main subway and open up public transportation, such as trams with small and medium-sized transportation systems. last mile. [0003] However, due to the non-closed right-of-way of trams, especially at public intersections, which share the right of way with passenger cars and pedestrians, the lower operating speed and efficiency of trams are closely related to the passing priority of intersections. At present, there have been many collisions between public passenger cars and trams at intersections, which...
