Vehicle speed induction control method for reducing probability that vehicle breaks yellow light

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...

Problems solved by technology

Although this reduces the risk of drivers running yellow lights, some unnecessary braking strategies reduce the operating efficiency of the traffic system, and may even cause certain traffic jams during peak hours

In addition, if the vehicle suddenly encounters a yellow light while driving at a high speed, if the driver brakes urgently to avoid rushing through the yellow light signal, it is likely to induce a rear-end collision of the vehicle behind and cause a traffic accident
