Intelligent traffic system for realizing high-grade automatic driving and efficient transportation

Abstract

The invention discloses an intelligent traffic system for realizing high-grade automatic driving and high-efficiency transportation, which mainly comprises five subsystems: a virtual track subsystem based on a high-precision map, and an intelligent traffic command subsystem which is positioned at an intersection and the like and has other crossed driving working conditions, wherein the intelligent driving vehicle, the motorcade movement and lane changing control subsystem, the road section entrance and exit entry and exit control subsystem and the coordination control subsystem based on the traffic network globally are located in the road section driving working condition. According to the invention, the increasingly mature automatic driving technology at present can be helped to achieve higher-level automatic driving, and by means of the controllability of automatic driving and the macroscopic and microscopic regulation and control of an intelligent traffic network, the transportation efficiency of the traffic network is improved, global control is realized, and congestion is prevented.

Description

technical field [0001] The invention relates to an intelligent transportation system for realizing high-level automatic driving and efficient transportation, in particular to a system for independently controlling the traffic conditions of intelligent driving vehicles on various road sections and intersections. Background technique [0002] In the mesh traffic network, there are two basic elements of the traffic network, one is the intersection on the traffic network, and the other is the connecting line between the intersections on the traffic network. [0003] In the increasingly congested traffic situation, many large cities have already used intelligent transportation systems to manage urban traffic conditions. At present, most of the intelligent traffic management stays at the macro level, such as the adjustment of traffic light duration, etc., aiming at the relative lane position of vehicles in the road section and the target lane of the intersection. Micro-level regul...

AI Technical Summary

Problems solved by technology

[0004] At present, the L2 level automatic driving technology is relatively mature, that is, the motion performance on the connecting line section between the intersections mentioned above is basically acceptable, but the automatic driving at the intersection is caused by building occlusion and limited perception ability of bicycles. The traffic capacity of the intersection is weak
