Abstract

The invention relates to the field of urban public transportation system and signal control, in particular to a green wave collaborative control optimization method for social vehicles and trams. The optimization method aims at reducing the secondary parking of trams, and optimizes the location of tram stations; aims at maximizing the green wave bandwidth weighted by the two-way tidal coefficient of the social vehicle arterial line; The green wave signal control optimization model of the social vehicle arterial line is constructed with the wave passage constraint as the constraint condition; the vehicle-road coordination mechanism is established according to the arterial intersection signal control scheme, and the stop time of the tram station is calculated. Based on the optimized arterial intersection signal control scheme, a vehicle-road coordination mechanism is established to calculate the stop time of tram stations. Utilize the location of the station to coordinate the signal scheme of the main line intersection, realize the green wave control of the main line social vehicles and avoid the secondary parking of the tram at the intersection, and ensure the operation efficiency of the ground traffic and the punctuality of the tram operation.

Description

Technical field [0001] The present invention relates to the field of urban public transport system and signal control, specifically to a social vehicle and tram green wave collaborative control optimization method. Background [0002] As a light rail transit system, trams have a more significant priority than conventional buses. However, the tracks of trams are mostly laid in the form of ground laying, and cross conflicts with other road traffic and pedestrians at the plane intersection, and the traffic organization is more complicated. [0003] At present, the control of trams mostly adopts the method of priority signal control, and adjusts the intersection phase for trams through induction control, so as to realize the continuous passage of trams at intersections. Shenyang Tram Line 5 adopts an absolute priority control method at some intersections; Shanghai Zhangjiang Tram adopts driver's lookout and manual adjustment of the stop time of the station to achieve tram stopless tr...
