Problems solved by technology

[0005] The existing Chinese patent 201210507080.0 proposes a method for judging urban road traffic status based on section detectors; a comprehensive congestion evaluation index, i.e. traffic congestion index, is constructed using three traffic flow parameters: traffic flow, speed, and time occupancy rate. The traffic congestion index judges the traffic status of the road section; however, this invention is based on the traffic information of a certain detection section on the road section, and the information collection is less, and the data accuracy is lower

Embodiment Construction

[0031] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032] Such as figure 1 As shown, a kind of lane vehicle traffic statistics system that the present invention proposes, this system comprises: server, vehicle-mounted controller; Described server and vehicle-mounted controller are connected by communication, preferably use safe communication connection. Said servers are prior art.

[0033] Such as figure 1 As shown, a traffic statistics system for lane vehicles proposed by the present invention also includes a management terminal, which is connected to a server through a communication system to manage the operation of the entire system; the m...

Abstract

The invention relates to traffic management, and specifically relates to a lane vehicle flow statistical system. The system comprises a server and vehicle-mounted controllers, and the server is in communication with the vehicle-mounted controllers. Each vehicle-mounted controller comprises a controller unit, a communication module and a positioning device. The positioning devices are of high precision, and can position vehicles on a lane. The system can position the vehicles on the lane through acquiring the accurate real-time positions of the on-road vehicles. The server calculates real-time vehicle flow velocity on the lane or the road according to preset road occupying coefficients of various types of the vehicles, makes statistics on the vehicle flow velocity on the lane or the road during any period, and predicts the vehicle flow velocity on the lane and the road in future periods, so that traffic management and navigation are facilitated.

Description

technical field [0001] The invention relates to traffic management, in particular to a lane vehicle flow statistics system. Background technique [0002] To reflect the vehicle flow on the lane or road, road vehicle flow and vehicle flow speed can be used. Road vehicle flow and road vehicle flow speed are important basis for traffic design, traffic management, and traffic navigation; especially real-time road vehicle flow speed can be used for real-time traffic management and traffic navigation; vehicle flow and vehicle flow speed accurate to the lane level It is also an important basis for traffic design, traffic management, and traffic navigation; real-time accurate vehicle flow and vehicle speed at the lane level are of great significance to real-time traffic scheduling and traffic navigation. [0003] The positioning accuracy of the existing differential satellite positioning system can reach the millimeter level, and is less affected by terrain and objects; in addition...
