Traffic signal control system and method for pedestrian crossing road

Abstract

The present invention provides a traffic signal control system of crossing roads for passerby and comprises an upper intersection signal control device and a passerby crossing road signal control device. The present invention is characterized in that a signal control processing device which is connected with the upper intersection signal control device and the passerby crossing road signal control device is also included. The present invention also provides a traffic signal control method of crossing roads for passerby. The traffic signal control system of crossing roads for passerby and the method thereof provided by the present invention control the passerby crossing roads and the upper intersection in phase. When a crosswalk is in passerby crossing road button type signal control mode, the crossing signal control of passerby crossing roads and the upper intersection signals are ensured to be controlled in phase to form a green wave band by optimization calculation of system, thus adequately enhancing the utilization rate of roads based on that the passersby has an adequate crossing road wayleave.

Description

technical field [0001] The invention relates to a traffic signal control system and method, in particular to a pedestrian crossing traffic signal control system and method. Background technique [0002] Modern transportation emphasizes "people-oriented". When solving the problem of horizontal pedestrian crossing on urban arterial roads, in order to facilitate pedestrian crossing, it is necessary to set up a pedestrian crossing between two adjacent intersections to facilitate pedestrian crossing. Pedestrian crossing is contradictory to the passage of vehicles on the main road. In order to facilitate pedestrian crossing and ensure that the passage of vehicles on the main road is not greatly disturbed, it is necessary to manage pedestrian crossing behavior at pedestrian crossings. [0003] There are mainly three types of management measures at the pedestrian crossings on main roads: [0004] ① Periodic signal control (signal control mode of ordinary intersections); [0005] ②...

AI Technical Summary

Problems solved by technology

[0006] ③No signal control

[0008] Pedestrian crossings using "pedestrian crossing button signal control" will always pass when there are no pedestrians crossing the street to ensure the right of way for motor vehicles on the main road. Uncertainty in the distribution of crossings often affects the normal passage of motor vehicles coming from upstream intersections, which is prone to congestion on arterial roads

[0009] The biggest problem with the existing scheme is that there is no coordinated control of the pedestrian crossing and the signal control state of the upstream arterial intersection.
