One-way pedestrian crossing control method based on vehicle-road coordination

Abstract

The invention discloses a one-way street pedestrian crossing control method based on vehicular access cooperation.According to the one-way street pedestrian crossing control method, vehicles, signal lamps, video detectors and the like are cooperatively controlled through a control center so as to achieve control of the pedestrian crossing signal lamps and timely speed reduction of the vehicles, accordingly pedestrian and vehicle conflictions on a one-way street are reduced, and the road traffic safety is improved.The one-way street pedestrian crossing control method comprises the following steps of traffic data acquisition, vehicle information collection performed by the control center, judgment whether the vehicles are in an influence zone, control of the pedestrian crossing signal lamps, speed reduction of the vehicles and the like.The one-way street pedestrian crossing control method is simple in design and easy to calculate and can accurately achieve vehicle speed control and the control of the pedestrian crossing signal lamps through vehicular access cooperation, reduce the pedestrian and vehicle conflictions on the one-way street and improve road traffic safety.The one-way street pedestrian crossing control method based on the vehicular access cooperation has a very practical engineering application value on the aspect of road traffic management and control.

Description

technical field [0001] The invention belongs to the technical field of intelligent traffic management and control, and in particular relates to a one-way pedestrian crossing control method based on vehicle-road coordination. Background technique [0002] With the continuous improvement of the living standards of Chinese residents and the rapid economic development in recent years, the number of domestic car ownership has increased rapidly. According to relevant data from the Ministry of Public Security, by the end of 2012, the number of motor vehicles in my country had reached 240 million, and the number of motor vehicle drivers had reached 260 million, and it is still growing. The rapid increase of motor vehicles has brought huge traffic pressure, and has also had a great impact on traffic safety. Statistics show that in 2010 alone, there were 210,821 traffic accidents across the country, causing as many as 65,000 deaths. Among the many accidents, conflicts between pedest...

Problems solved by technology

However, there are two obvious defects in the existing control method. First, due to the unreasonable setting of signal light timing, pedestrians often cross the street by crossing the red light, which leads to the inability to detect the high-speed vehicles on the one-way street in time, resulting in serious traffic accidents; secondly. , the existing control methods cannot coordinate the control of vehicles and pedestrians crossing the street, which limits the running speed of vehicles on one-way streets and is not conducive to making full use of road resources
