Embodiment Construction

[0032] The specific embodiment of the present invention is described in further detail below in conjunction with accompanying drawing:

[0033] The schematic diagram of the application scene of the present invention is as follows figure 1 shown. The core control idea is to give priority to the clearance of vehicles at the upstream intersection, and on this premise, to maximize the clearance of pedestrian crossing requests.

[0034] If the vehicles at the upstream intersection are clearing, if there is a request for pedestrians to cross the street at this time, the request will be recorded but not released immediately, and the pedestrians will be released after the vehicles with coordinated phases are released. In this way, the vehicles with coordinated phases will not be hindered by the pedestrians in the middle, which ensures the coordination effect and traffic efficiency.

[0035] If there are multiple pedestrian requests, if the time allowed for the clearance interval is ...

Abstract

The invention discloses a road segment pedestrian crossing controlling method based on vehicles on upstream and vehicles on downstream coordinated. According to the road segment pedestrian crossing controlling method based on the vehicles on the upstream and the vehicles on the downstream coordinated, firstly judging whether present time in within a crossing allowing range when a pedestrian sends out a request, if the present time is within the crossing allowing range, the request of the pedestrian is executed in a conditioned mode after the judging of guiding time and the longest waiting time TWM of the pedestrian, if the resent time is not within the crossing allowing range, the request of the pedestrian can not be executed immediately and can be executed until the request is in the crossing allowing range, and if the request of the pedestrian reaches to the longest waiting time TWM, the pedestrian is allowed to cross immediately. According to the road segment pedestrian crossing controlling method based on the vehicles on the upstream and the vehicles on the downstream coordinated, coordinating effect of the vehicles on the upstream and the vehicles on the downstream is prevented from being destroyed, safe travelling of pedestrians and timely responsiveness of the request are completely considered, intelligent controlling degree of roads is improved, and positive effect on order and smooth releasing of urban vehicles is achieved.

Description

technical field [0001] The invention relates to the field of intelligent traffic control, in particular to a control method for road section pedestrian crossing in an urban traffic signal control system. Background technique [0002] The main participants in urban traffic include vehicles and pedestrians. Pedestrians and vehicles compete for the right of way on the road. The two interact and influence. Whether the pedestrian traffic control is reasonable, orderly, and efficient can have a direct impact on the efficiency of vehicle clearance, thereby affecting the operation of the entire urban traffic control system. Effect. Therefore, the control of pedestrian clearance has been paid more and more attention by people, and it has become an important research topic for intelligent traffic designers. [0003] There are mainly two types of control points for pedestrian clearance: [0004] 1. It is located at the intersection of roads, such as urban crossroads and T-shaped int...
