Multistage traffic responsive type signal control method for road section pedestrian crossing

Abstract

The invention provides a multistage traffic responsive type signal control method for road section pedestrian crossing, comprising steps of installed a set of automobile signal lamps on automobiles in each passing direction, installing four sets of pedestrian signal lamps on two ends of the sidewalk and on a pedestrian street crossing safety island, wherein the automobile signal lamps belong to the same one automobile phase, and the pedestrian signal lamps belong to the same one pedestrian phase, presetting two working states which are for the automobiles to pass for a long time and for the automobiles and the pedestrians to pass alternatively , installing an annular coil detector at the position which is 40 meters up from a stop line of each automobile road, installing a pedestrian requiring button on each pedestrian signal lamp rod, and utilizing signal time distribution data and traffic detection data to constitute various traffic incidents. In the controlling process, time frame division is not needed, and the dynamic adjustment of the signal lamp colors of the automobiles and the pedestrians is realized, continuous time of any working state is automatically extended and the various working states can be automatically switched by using the traffic accidents happen in real time as driving mechanism.

Description

technical field [0001] The invention belongs to the technical field of intelligent traffic control, and relates to a multi-level traffic responsive signal control method for pedestrian crosswalks in road sections. Background technique [0002] Pedestrian crossing facilities include plane crossing facilities and three-dimensional street crossing facilities. Pedestrian crosswalks are the most common and convenient and labor-saving plane crossing facilities, usually set at intersections and road sections. [0003] When the signal-controlled intersections along the main urban road are far apart, pedestrian crosswalks should be set up at places where pedestrian crossing needs are relatively concentrated. In order to standardize the order of traffic operation and reduce the hidden dangers of traffic accidents, it is advisable to implement traffic signal control on pedestrian crossings in road sections with greater traffic demand for motor vehicles or pedestrians. [0004] The se...

AI Technical Summary

Problems solved by technology

In view of the significant time-varying and random nature of pedestrian crossing demand, no matter whether the division of control periods is reasonable or not, no matter what traffic operation mode is adopted, it will face unnecessary damage to the interests of motor vehicles caused by sudden changes in pedestrian crossing demand
