Abstract

The invention discloses an expressway traffic state sensing system based on a wide area radar and belongs to the technical field of traffic state monitoring. The wide-area-radar-based highway trafficstate sensing system comprises a wide-area radar subsystem, a data transmission network and a central platform that are connected successively, wherein the wide-area radar subsystem is used for collecting traffic data and accessing a data transmission network, the data transmission network is used for transmitting the traffic data to the central platform, and the central platform is used for carrying out event detection, trajectory tracking, event prediction analysis, historical event statistics and equipment management of the traffic data. The system is advantaged in that problems that an existing traffic state sensing system excessively depends on hardware and network resources, timeliness is low, and road conditions cannot be sensed in time under severe weather conditions are solved.

Description

technical field [0001] The invention belongs to the technical field of traffic state monitoring, and relates to a highway traffic state perception system based on wide-area radar. Background technique [0002] With the development of society and economy, the number of vehicles has increased rapidly, and the traffic flow of expressways has become larger and larger. At the same time, people's requirements for traffic service level are getting higher and higher. How to achieve and guarantee faster, more efficient and safer traffic under the increasing traffic pressure is becoming more and more prominent. [0003] To achieve and guarantee faster, more efficient and safer traffic, it is necessary to grasp the first-hand information of the traffic scene in a timely and accurate manner, and make predictions and decisions based on the actual situation combined with historical data to solve on-site problems and ensure smooth traffic , Prevent accidents from happening. [0004] Mos...
