Method for safety control of highway entrance ramp based on vehicle-vehicle networking

Abstract

The invention discloses a method for safety control of a highway entrance ramp based on vehicle-vehicle networking.According to the method, vehicles of a mainline and an entrance ramp are subject to vehicle-vehicle networking through a control center, so as to achieve timely speed reduction and lane changes of vehicles, reduce traffic accident rate of the highway entrance ramp and improve traffic safety of a highway.The method comprises the steps of traffic data collection, vehicle information collection by the control center, collision risk judgment, vehicle safety speed reduction and lane change and the like.The method is simple in design and easy to calculate; through vehicle-vehicle networking, vehicle speed control and lane change operations can be performed accurately, road traffic accidents are reduced, and traffic safety of the highway is effectively improved.The method for safety control of the highway entrance ramp based on vehicle-vehicle networking has very practical engineering application values in the aspect of highway 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 safety control method for highway entrance ramps based on vehicle-to-vehicle networking. 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, improper mergi...

However, there are two obvious defects in the existing control method. First, the way of guiding the vehicles on the main line through the signal board is too passive and cannot actively control the vehicles on the main line. Some vehicles fail to recognize the signal board information in time or do not obey the guidance. At this time, if there are incoming vehicles on the entrance ramp, it will easily lead to serious traffic accidents. In this case, the control effect is difficult to guarantee. Entering the inner lane in order to avoid collision accidents, this control method reduces the utilization efficiency of the outer lane and is not conducive to making full use of the road resources of the expressway
