Embodiment Construction

[0108] The present invention will be further explained below in conjunction with the drawings.

[0109] First, the following description of the reference signs in the drawings:

[0110] 101—TCC / TCU Traffic Management System: A hierarchical traffic control center TCC and traffic control unit TCU, used for information processing and the formulation of traffic control instructions. The traffic control center TCC is an automatic or semi-automatic computing center with the functions of data integration, information processing, network optimization, and timing of regional traffic control signals. The traffic control unit TCU is a smaller traffic control unit with similar functions, but it covers a smaller control range, such as ramps, intersections, etc.

[0111] 102—Roadside unit system: A roadside unit RSU network that receives data streams from networked vehicles, detects traffic conditions, and sends target instructions to vehicles. The roadside unit system realizes the functions of ...

Abstract

The invention provides an intelligent connected traffic system, which is based on a system, applicable to different vehicle types and road levels and can realize automatic vehicle control. The intelligent connected traffic system particularly comprises the following subsystems: a traffic management system (1), a road-side unit system (2), a vehicle subsystem (3) and a communication system (4), wherein the traffic management system comprises a traffic control center and a traffic control unit which are layered for processing information and making a traffic operation instruction; the road-sideunit system is composed of a road-side unit for acquiring a data stream from a connected vehicle, detecting a traffic state and sending a target instruction to the connected vehicle; the vehicle subsystem is composed of a mixed vehicle flow with different connection degrees and automation degrees; and the communication system is used for providing wired or wireless communication service for all entities in the system. The driving control task and the algorithm between a vehicle and a traffic control network and a roadside unit network are re-adjusted and optimized, and a safer, more reliable and more economic traffic control and management solution is provided.

Description

Technical field [0001] The present invention relates to an integrated system that provides complete vehicle operation and control for Connected and Automated Vehicles (CAV). More specifically, it relates to a traffic management and control system for controlling intelligent connected vehicles. Each vehicle sends specific time-sensitive control commands, including vehicle following, lane changing, and route guidance. Background technique [0002] Self-driving vehicles, that is, vehicles capable of sensing the surrounding environment and realizing cruising without driver control or a small amount of driver operations, are under development. At present, self-driving vehicles are mainly in the experimental testing stage and have not yet been put into extensive commercial applications. The existing method requires an expensive and complex vehicle-mounted system, which brings difficulty in application and promotion. Summary of the invention [0003] The present invention provides an i...
