Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] like figure 1 Shown is an overall flow chart of a vehicle speed induction control method for reducing the probability of a vehicle running a yellow light. Combine below figure 1 The method of the present invention is further described.

[0028]The vehicle speed induction control method for reducing the probability of a vehicle running a yellow light in the present invention detects the running state of the vehicle in real time and collects the speed and position information of the vehicle. By comparing the operation of the vehicle with the signal timing scheme of the downstream intersection, the signal phase when the vehicle arrives at the intersection is predicted, and the vehicle is induced to pass through the intersection at an optimal speed or take braking measures to reduce vehicle rush. Yellow light risk. It includes the basic traffic data collection s...

Abstract

The invention discloses a vehicle speed induction control method for reducing probability that a vehicle breaks a yellow light. The method comprises the steps of basic transportation data collection, vehicle running state detection, vehicle running state judgment, and automatic vehicle speed induction control. According to the method, detection of vehicle running state and collection of speed and position information of a vehicle are carried out in real time through a vehicle-mounted global position system (GPS). Comparison is carried out through running data of the vehicle and a signal timing scheme of a downstream intersection, a possible signal phase when the vehicle reaches the intersection is prejudged, and the vehicle is pointedly induced to run through the intersection at the optimal running speed or braking measures is timely adopted to reduce risks that the vehicle breaks the yellow light. According to the method, an existing road network configuration and signal control mode is needless to change, investment is small, calculation and actual operation are benefited through the method, practicability is strong, running efficiency of motor vehicles on intersections can be promoted, transportation safety is guaranteed, and great practical significance is achieved.

Description

technical field [0001] The invention belongs to the field of urban traffic operation and organization technology and traffic control, and relates to a vehicle speed induction control method for reducing the probability of vehicles running yellow lights. Background technique [0002] At present, my country is in a critical period of rapid development of social economy and urbanization process, with the continuous expansion of urban scale, continuous population growth, rapid economic development, and the continuous increase of private car ownership. However, with the increase in car ownership, traffic accidents in cities, especially at intersections, are also increasing: According to statistics from the Ministry of Public Security, in 2012, a total of traffic violations that did not follow the instructions of traffic lights were investigated and dealt with nationwide. There were 26.49 million cases, an average of more than 70,000 cases per day; 46,000 intersection traffic acci...
