STUDY FOR INTELLIGENT COOPERATIVE CONTROL SYSTEM OF TRAFFIC SAFETY ON FREEWAY

摘要

The paper analyzed the influence factors of freeway safety driving speed and indicated the fatalness of speeding on freeway. In order to prevent and avoid traffic accidences, the paper investigated the architecture of freeway transportation safety intelligent cooperative control system based on safety driving speed. The main function of this system is introduced and the integrated model has been established for cooperative warning and control of traffic safety. At the same time, the key techniques, such as real time safety information collection, interactive communication, and safety coordinating control method, were studied. The mode of cooperative safety control is put forward by using ITS and GIS/GPS and information system of safety cooperative control. The integrated architecture of safety cooperative control is established, which realized real time inspection and monitoring of traffic speed.
