Embodiment Construction

[0077] In order to describe the technical content of the present invention more clearly, further description will be given below in conjunction with specific embodiments.

[0078] The method for realizing anti-congestion control of trams based on the road traffic state of the present invention comprises the following steps:

[0079] (1) Judging the congestion situation of each bottleneck road section when multiple bottleneck road sections are congested at the same time, and taking the bottleneck road section with the largest congestion level as the control target;

[0080] (1.1) judge whether the bottleneck section corresponding to the upstream intersection is greater than 1, if yes, then continue step (1.2); otherwise, continue step (2);

[0081] (1.2) Judging whether the congestion level of each bottleneck road section is the same, if yes, then do not adjust the signal timing, and exit the step; otherwise, take the bottleneck road section with the highest congestion level as...

Abstract

The invention relates to a method for realizing tramcar anti-congestion control based on a road traffic state. The method comprises the following steps of: (1) judging the congestion condition of eachbottleneck road section when the plurality of bottleneck road sections are congested at the same time, and taking the bottleneck road section with the maximum congestion level as a control target; (2) judging whether the bottleneck road section is congested or not, and if so, continuing to execute the step (3), and otherwise, calculating and storing a fine adjustment signal timing scheme; and (3)calculating the adjustment scheme of the congestion condition of the bottleneck road section. By adopting the method, the number of vehicles converging into the congested road sections at upstream and downstream intersections is automatically adjusted, and the queuing length of vehicles at key intersections is effectively reduced; an optimal signal timing adjustment scheme is automatically generated by adopting a method based on the combination of intersection flow data and fixed modes; tramcar anti-congestion control is carried out on key areas; and on the premise of overall coordination, atramcar priority passage right is given, the punctuality of tramcars is guaranteed as much as possible, and traffic congestion during peak hours is effectively relieved.

Description

technical field [0001] The invention relates to the field of traffic signal control, in particular to the field of intelligent traffic signal control of urban trams, in particular to a method for realizing anti-congestion control of trams based on road traffic conditions. Background technique [0002] In 2018, the construction of Tram Lines T1 and T2 in Songjiang District, Shanghai has basically taken shape. Unlike subways, light rails and other rail transit, the operation organization of modern trams is subject to the influence of road intersection signals, the phase of traffic signals at intersections, Design indicators such as cycle times and delays directly affect the operational quality of trams. The operating timetable of trams in European countries is coordinated with the signal lights at intersections, and the signal priority is more guaranteed than that of buses. In Germany, there is a separate set of tram signal lights in areas with dense tram lines, which are sep...
