Intelligent signal control method for passively prioritizing pedestrians

Abstract

An intelligent signal control method for passively prioritizing pedestrians comprises the following steps that 1, inputting preset initial green light time of each phase, and detecting whether vehicles pass through corresponding lanes or not and corresponding conditions of traffic flow through a vehicle detector; 2, sequentially operating each phase, prolonging the green light time on the basis ofincreasing the initial green light time of the motor vehicle of the corresponding lane when a continuous vehicle passes through, and entering the next phase according to the initial green light timeif no traffic flow passes through; and 3, setting the maximum green light time of each phase, entering an indicator light changing stage under any condition after the maximum green light time is reached, obtaining induction signal parameters in real time, preparing to enter the next phase, and continuing to repeat the operation above in the next phase. The method can guarantee the rights and interests of pedestrians at the intersection, completely meets the passing demands of motor vehicles in the peak period and the flat peak period, and also adapts to the condition where the traffic volume fluctuation of the motor vehicles is large.

Description

technical field [0001] The invention belongs to the technical field of intelligent traffic control, in particular to an intelligent signal control method with passive priority for pedestrians. Background technique [0002] In various traffic activities, pedestrians are obviously weaker than motor vehicles in terms of speed and confrontation ability; at the same time, pedestrians are more dangerous because of their large demand, slow speed, and high degree of freedom. Among various traffic activities, pedestrian crossing is a type in which pedestrians are seriously threatened by motor vehicles. This is because the trajectory of pedestrians is perpendicular to the direction of motor vehicle movement when crossing the street, and pedestrian flow is completely exposed to motor vehicle flow. Pedestrians cannot guarantee their own safety and road priority. [0003] Especially in the case of large urban road intersections where there is a large demand for pedestrian crossing, the ...

AI Technical Summary

Problems solved by technology

This release method is more restrictive when there is a large demand for pedestrians to cross the street. When the motor vehicle flow at the intersection is small, the green light time set according to the motor vehicle flow will not be able to meet the time requirements for pedestrians to cross the street; When the motor vehicle flow is large, the waiting time of pedestrians will exceed the tolerance range of pedestrians
