Intelligent traffic signal control system considering safety of cross-street pedestrians

Abstract

The invention provides an intelligent traffic signal control system considering the safety of cross-street pedestrians; the intelligent traffic signal control system comprises inductance coil detectors, video detectors, a traffic signal controlling machine and signal lamps; a two-phase total-inductive control mode is adopted in a road crossing; the two inductance coil detectors are embedded in each inlet lane, wherein the main inductance coil detector is embedded at a stop line of the inlet lane and is used for detecting traffic flow of a road section; the auxiliary inductance coil detector is embedded at the possible maximum queuing part of an advanced position of the main inductance coil detector and is used for assisting the main inductance coil detector to detect motor vehicles; pedestrian cross-street waiting areas at two ends of each pedestrian crossing are respectively provided with the video detector for detecting flow of crossing pedestrians; the traffic signal controlling machine carries out data exchange with the main inductance coil detector, the auxiliary inductance coil detector and the video detectors by data lines and simultaneously controls the signal lamps positioned at the pedestrian crossing and the road crossing by the data lines. According to the intelligent traffic signal control system, the safety and the passing efficiency of the cross-street pedestrians can be realized, and the passing rate of the motor vehicles is ensured.

Description

technical field [0001] The invention relates to a traffic signal control system, in particular to a pedestrian crossing induction signal control system, which is mainly aimed at the safe crossing control of pedestrians at urban road intersections. Background technique [0002] With the continuous acceleration of urban motorization and the gradual development of slow-moving traffic, the crosswalk at the intersection is used as the infrastructure for pedestrians to cross the street. Because pedestrians cross the road, they conflict with motor vehicles driving on the main road, which seriously affects the safety of the entrance road. capacity. At present, the main traffic control methods for pedestrians crossing the street at intersections are: timing signal control, button signal control and no signal control. At intersections with relatively large motor vehicle traffic flow, in order to ensure the efficiency of road traffic, timing signal control is generally used for pedest...
