A two-way green wave coordinated control method based on the red light queuing dissipation constraints in the improved maxband model

Abstract

The invention discloses a bidirectional green wave coordination control method based on red lamp queue clearance constraint condition in an improved MAXBAND model. The method comprises the following steps of determining a single-point timing scheme of each intersection in trunk coordination; determining a common period of a coordinated road segment; correcting a constraint condition in a traditional MAXBAND model, wherein the step comprises correcting a green conflict constraint condition and an integral-time period constraint condition, and adding a head vehicle constraint condition and a determining screening condition; and through correction in a previous step, finally subdividing a MAXBAND model into two models, namely a model A and a model B, and solving by means of the improved MAXBAND model algorithm. According to the bidirectional green wave coordination control method, through performing geometric meaning correction on the red lamp queue clearance time in the traditional MAXBAND model, the determining screening condition of the algorithm model and the constraint condition of head vehicle mode are added, and a green wave coordination problem in actual engineering can be more accurately described and settled, thereby realizing an effect of improving optimal controlling in trunk bidirectional coordination.

Description

technical field [0001] The invention relates to the field of road traffic signal control optimization in the field of intelligent transportation, in particular to a two-way green wave coordinated control method based on the red light queuing dissipation constraints in the improved MAXBAND model. Background technique [0002] In the field of traffic signal control optimization, according to the difference of optimization objectives, coordinated control methods of urban arterial lines can be roughly divided into two categories, one is based on delay minimization, and the other is based on bandwidth maximization. Among them, the minimum delay method is to calculate the delay time and parking times of the vehicle, and find out the relationship between the traffic signal parameters and traffic performance indicators in the road network, and then obtain the signal timing scheme under the minimum delay as the best Timing scheme. The other is the maximum green wave bandwidth method...
