Abstract

The invention relates to a pedestrian crossing control system and method based on upstream-downstream signal intersection coordination. Timely response to road segment pedestrian crossing can be ensured, trunk line coordination effect of adjacent upstream-downstream signal intersections can be guaranteed, reminding of pedestrian crossing waiting passing countdown can be realized to assist pedestrians in safe crossing, and impact on trunk line coordination control effect is reduced. The system comprises a pedestrian crossing signal triggering device, signal countdown equipment, a signal machinecontrol subsystem and a central optimized control subsystem. When receiving a pedestrian crossing request signal, the signal machine control subsystem sends information to the central optimized control subsystem, the central optimized control subsystem generates pedestrian crossing signal timing plan information and countdown information in real time, and the signal machine control subsystem controls on-off and lamp color conversion of signal lamps according to the pedestrian crossing signal timing plan information and forwards the countdown information to signal countdown equipment for display.

Description

technical field [0001] The invention belongs to the technical field of urban road traffic signal control, and in particular relates to a pedestrian crossing control system and method based on the coordination of upstream and downstream signal intersections. Background technique [0002] In the existing urban traffic arteries, for the convenience of pedestrians crossing the street, crosswalk zebra crossings are often set between adjacent upstream and downstream intersections. However, the pedestrian crossing signals on the existing road sections are often not effectively coordinated and controlled with the signals at the upstream and downstream adjacent intersections, which makes the traffic flow of the urban traffic arteries stop and go, and the traffic is not smooth, which reduces the comfort of traffic driving. When the traffic flow at an intersection fails to pass within the green wave bandwidth due to the impact of pedestrian crossing, the traffic flow in the next cycle ...
