Dynamic traffic signal control method for pedestrian secondary crossing intersection

Abstract

The invention discloses a dynamic traffic signal control method for a pedestrian secondary crossing intersection. The method comprises the steps: carrying out the real-time monitoring of the green light display time of a signal lamp, the waiting time of pedestrians waiting for the secondary crossing on a safety island, and the number of pedestrians waiting for the secondary crossing on the safety island, and according to a monitoring result and a preset dynamic signal control logic, dynamically adjusting the intersection signal timing scheme; and increasing the secondary crossing safety and efficiency of pedestrians and the crossing efficiency of motor vehicles. According to the invention, the green light duration is dynamically allocated according to traffic requirements under the condition of considering pedestrian crossing safety and intersection operation efficiency, and the operation efficiency of the secondary crossing intersection is improved.

Description

technical field [0001] The invention relates to the field of traffic management control, in particular to a method for controlling dynamic traffic signals at pedestrian secondary crossing intersections. Background technique [0002] The characteristic feature of traffic flow across the street is mixed traffic flow across the street, including slow traffic crossing of pedestrians is also a crucial part. The rapid growth of urban motorized travel has further exacerbated traffic problems such as traffic congestion, road traffic safety, traffic energy consumption, and traffic environmental pollution. On the contrary, slow traffic has the advantages of environmental protection and good health, and has become the current mode of transportation. The efficiency of pedestrian crossing often affects the efficiency of the entire traffic flow. The improvement of pedestrian crossing efficiency is necessary for the implementation of the "slow traffic priority" policy. condition. [0003...

AI Technical Summary

Problems solved by technology

Existing intersection organization and control methods often weaken or even completely ignore pedestrian indicators, resulting in large delays for pedestrians to cross the street again, which in turn leads to organizational confusion and random running of red lights, which further interferes with the normal operation of motor vehicles and reduces the operation of the entire intersection. efficiency
