Problems solved by technology

[0005] In view of the different advantages, disadvantages and scope of application of signal priority and green wave, signal priority trams can pass without stopping at all (when the absolute priority scheme is adopted), but it has a greater impact on road traffic flow in conflicting directions. The intersection may cause congestion; while the green wave has no obvious impact on the effective passing time of each conflicting direction, but only when the space-time trajectory of the tram is within the bandwidth of the green wave, can the tram pass without stopping at the intersection, while in When the number of intersections included in the green wave coordination is too large, the green wave bandwidth becomes very narrow, and the tram will miss the green wave belt under the slight fluctuation of the interval running time, and will still stop and wait at the intersection

Abstract

The invention provides a control method for tram operation, and further provides a control system for tram operation. The control method comprises the following steps that S100, basic parameters are obtained; S200, decision variables are calculated, specifically, the decision variables are calculated according to the basic parameters obtained in the step S100; and S300, the decision variables areapplied, specifically, the decision variables obtained in the step S200 are applied to signal lamp layout of intersections along the tram line. According to the control method for tram operation, thetram full-line passing efficiency and service level can be improved, and the traffic development idea of public transport priority is embodied; and under the premise of public transport priority, thepassing efficiency of road traffic can also be balanced.

Description

technical field [0001] The invention belongs to the field of train control, in particular to a control method and system for tram running. Background technique [0002] The mixed right-of-way of trams means that trams have independent right-of-way on road sections, but share the right-of-way with road traffic at intersections. Mixed right-of-way is a basic feature of modern trams. Under mixed right-of-way, how to ensure that trams pass through intersections efficiently and have the least impact on road traffic requires a comprehensive consideration and trade-off of the two to make a plan decision . Signal priority and green wave are two typical streetcar intersection passing technologies. As far as the signal priority is concerned, by dynamically coordinating the arrival time of the tram with the intersection signal, it is a technical strategy to provide the tram with the right of way to pass the intersection without stopping. When the tram travels to a certain distance f...
