Embodiment Construction

[0019] specific implementation plan

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that this example is only for illustrating the present invention and not intended to limit the scope of the present invention. The present invention proposes an intersection traffic control method under the condition of mixed traffic of automatic driving and manual driving vehicles, the operation flow chart is as follows figure 1 As shown, its specific implementation process includes the following modules:

[0021] (1) Intersection environment settings

[0022] Such as figure 2 As shown, the research object of the present invention is a level intersection environment. The intersection shown in the figure is a typical four-entrance intersection, and each entrance has three lanes. The entrance lanes are from the inside to the outside. Driving in special lanes and mixed lanes, where only lim...

Abstract

The invention is directed to intersection traffic control under an automatic driving and manual driving vehicle mixed traveling condition, and designs an advanced control method to improve the trafficefficiency of the mixed traveling condition under the premise of ensuring safety. First, entrance lanes of intersections are divided into automatic driving lanes, manual driving lanes and mixed traveling lanes. Secondly, for vehicles arrived, according to the types of the vehicles, lanes are selected, right-turning vehicles enter the mixed traveling lanes, and straight-forward and left-turning vehicles respectively enter respective dedicated lanes. A new signal timing scheme is designed, the manual driving vehicles are still in accordance with the signal timing scheme in the intersections totravel, while the automatic driving vehicles pass through at the full red time of a signal period, and self-organized traffic based on position reservation is adopted to avoid conflicts.

Description

technical field [0001] The invention belongs to the field of intelligent transportation, relates to technologies related to Internet of Vehicles, automatic driving, and signal control, and provides a solution for intersection traffic control under the condition of mixed traffic of automatic driving and manual driving vehicles to ensure vehicle travel safety. Background technique [0002] The technologies related to self-driving vehicles have developed rapidly in recent years, and a small number of self-driving vehicles have passed the test experiments and are driving on the road one after another. The technical architecture of self-driving vehicles mainly includes three parts: environment perception, intelligent decision-making and vehicle control. The remote control center performs information processing, decides the safe driving trajectory of the vehicle, and finally transmits the command to the vehicle controller to realize the vehicle movement. The technology of autonom...
