Problems solved by technology

Modern trams usually use ground-laid tracks in the middle of the road or on the side of the road. There are traffic conflicts between trams in the middle of the road and motor vehicles at level intersections, and the traffic organization method is relatively complicated. If there is no reasonable and effective signal control scheme, Not only will it lead to increased delays of trams and social vehicles at intersections, reduced traffic efficiency, but also easily lead to traffic accidents
[0003] At present, the research objects of domestic and foreign scholars on green wave are mainly so

Embodiment Construction

[0071] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0072] A green wave coordinated control method for trams on a left-turn line in the middle of the road disclosed in the embodiment of the present invention mainly includes the following steps:

[0073] S1. Obtain the road section geometric parameters and traffic parameters, intersection signal control parameters, social vehicle driving performance parameters, tram driving performance parameters, and tram stop parameters required for the green wave design of the left-turn line tram. Specifically include:

[0074] Collect intersection distance and road flow information: use traffic collection equipment (including but not limited to: electromagnetic induction, ultrasonic induction, video surveillance, etc.) to obtain the traffic flow demand of each road;

[0075] Determine the single-point timing scheme of each intersection in the main line: the ...

Abstract

The invention discloses a green wave coordination control method and device for an on-road left-turn line tramcar. According to the method, a mixed integer linear programming model taking the maximumweighted sum of the two-way green wave bandwidths of social vehicles as an optimization target is designed; the constraint conditions comprise social vehicle green wave system constraints, tramcar green wave system constraints, interaction constraints between the two green wave systems and signal period duration constraints; and an optimal solution of social vehicle green wave bandwidth is obtained on the basis of preferentially satisfying tramcar green wave passage of the left-turn line. According to the invention, green wave optimization can be carried out on bidirectional social vehicles and tramcars, the traffic efficiency of the tramcars and the social vehicles on the left-turn line is considered, and the parking frequency and the delay level of the tramcars and the social vehicles atthe intersection are effectively reduced.

Description

technical field [0001] The invention relates to the field of road traffic signal control in the field of intelligent transportation, in particular to a green wave coordinated control method and device for streetcars on left-turn lines in the middle of the road, on the basis of meeting the green-wave bandwidth requirements of trams on left-turn lines, Maximize the green wave bandwidth of social vehicles. Background technique [0002] With the rise of the concept of green travel, modern trams that save energy, improve energy efficiency, reduce pollution, and take efficiency into account have become the backbone of public transportation in small and medium-sized cities. Modern trams usually use ground-laid tracks in the middle of the road or on the side of the road. There are traffic conflicts between trams in the middle of the road and motor vehicles at level intersections, and the traffic organization method is relatively complicated. If there is no reasonable and effective s...
