Problems solved by technology

However, due to the different traffic operation characteristics of motor vehicles and pedestrians, their travel time resource requirements are also described in different ways, and the signal timing method of ordinary signalized intersections cannot be applied to signalized crosswalks

Embodiment Construction

[0047] A two-way urban main road has 6 motor vehicle lanes, and it is planned to set up 2 split road section signals to control pedestrian crossings within a certain distance along the road. Driving direction 1 is the main direction of the motor vehicle (see Figure 5 ).

[0048] Road space conditions include:

[0049] (1)D 1 =D 2 =100m, 150m, 200m, 250m, 300m;

[0050] ( 2 ) = D R 1 = D R 2 = 10 m .

[0051] Transportation requirements include:

[0052] ( 1 ) Q K 1 , d 1 = Q K 1 , d 2 = 1201 pcu / h , Q K 2 , ...

Abstract

The invention relates to a method for controlling a coordinating signal of adjacent splitting type road signal control pedestrian crosswalks. The method comprises the following steps of for a single splitting type road signal control pedestrian crosswalk, according to a time and distance relationship of a pedestrian, establishing a maximum street crosswalk time calculating method of the pedestrian; for the adjacent splitting type road signal control pedestrian crosswalks along an urban trunk road, according to a time and distance relationship of locomotives, at the premise of guaranteeing the bidirectional green wave effect of the locomotives, minimizing the maximum value of the maximum street crosswalk time of the pedestrian at any pedestrian crosswalk and any walking direction as a target, and adopting an integer nonlinear programming method to establish a coordinating signal timing and optimizing model. The method has the advantages that the model structure is simple, the undetermined parameters are fewer and can be easily determined, multiple transportation running methods can be provided for the locomotives and the pedestrians, the passing time resource supply and demand relationship of the locomotives and the pedestrians can be flexibly adjusted, the practicality is good, the suitability is wide, and the method can be popularized and applied in engineering practices.

Description

technical field [0001] The invention belongs to the technical field of traffic engineering, and relates to a coordinated signal control method for signal control of adjacent split-type road sections to control pedestrian crossings. Background technique [0002] The symbols involved in the following text are explained as follows: [0003] [0004] [0005] Pedestrian crossing facilities include plane crossing facilities and three-dimensional street crossing facilities. Pedestrian crosswalks are the most common plane crossing facilities, usually set at intersections and road sections. [0006] When the signal-controlled intersections along the main urban road are far apart, pedestrian crosswalks should be set up at places where pedestrian crossing needs are relatively concentrated. In order to standardize the order of traffic operation and reduce the hidden dangers of traffic accidents, it is advisable to implement traffic signal control on pedestrian crossings in road...
