Traffic safety sensing network based on mobile information

Abstract

The invention discloses a traffic safety sensing network based on mobile information for road intelligent traffic management. The traffic safety sensing network takes a vehicle as a mobile intelligent sensing node and forms into a sensing network with a mobile communication network and a traffic monitoring center. A vehicle-mounted positioning system and a vehicle-mounted sensor immediately acquire the position and the speed of the vehicle as well as the image information in and out of the vehicle, thereby providing real-time road traffic condition information to a traffic monitoring center; and a monitoring vehicle and the traffic monitoring center can perform various information interaction through a mobile communication network. With a vision sensor and a vehicle driving status identifying system, the traffic safety sensing network has the functions for acquiring and processing the image, can realize the functions for monitoring the illegal driving and reappearing the traffic scene, assisting the safe driving of the vehicle, provides a new traffic and vehicle supervising route for the traffic management department, can improve the traffic capability of the road, can improve the driving safety of drivers, and effectively avoids and reduces the personal injury and the economic loss caused by traffic accident.

Description

technical field [0001] The invention relates to a traffic safety monitoring system, in particular to a traffic safety perception network based on mobile information. Background technique [0002] With the continuous improvement of my country's economic development and motorization level, urban traffic congestion is becoming more and more serious. In the face of massive traffic information data, the traditional traffic management mode can no longer meet the actual needs. In recent years, urban traffic accidents, traffic congestion and other problems have caused great losses to society and economy. It has been fully realized that relying solely on on-site traffic police management cannot meet the needs of future traffic management. Therefore, it is an inevitable trend to conform to the development of the times to realize the intelligentization of traffic management. Under the background of the rise of sensor network industry, the establishment of traffic safety perception ne...

Problems solved by technology

However, there are deficiencies in this method. Fixed data acquisition equipment cannot directly measure data such as vehicle density and vehicle speed. The required data is obtained only through indirect measurement and complex algorithm estimation, and the measurement accuracy is limited; a large amount of investment in fixed data acquisition equipment is installed Huge, the installation of sensors under the road surface will destroy the road, the det
