Abstract

A traffic information transceiving interactive system based on dedicated short range communication (DSRC) is composed of a remote subscriber unit (RSU), a vehicle-mounted traffic information transceiver and a traffic control office database service system, wherein the vehicle-mounted traffic information transceiver transmits traffic accident information to the RSU through the DSRC, the RSU transmits the received data to peripheral vehicles, nearby RSUs and the traffic control office database service system so as to achieve real-time sharing of traffic accident information. The traffic information transceiving interactive system has the advantages that on one hand, accident occurrence conditions of each road section can be known by other vehicles in real time conveniently so as to effectively avoid traffic jam and on the other hand, traffic information can be timely submitted to a transportation bureau for timely handling of the traffic accidents.

Description

technical field [0001] The invention relates to the fields of DSRC (Dedicated Short Range Communications, dedicated short-range communication technology) communication, intelligent transportation, Internet of Vehicles, and vehicle-mounted traffic information service terminals, and specifically relates to a general-purpose multi-mode vehicle-mounted convenient traffic message transceiver. Background technique [0002] With the rapid development of my country's road traffic, the incidence of traffic accidents is on the rise. Since the occurrence of traffic accidents not only caused a large number of casualties and brought misfortune to countless families, but also seriously affected economic development and social stability, it has aroused great attention and concern from governments at all levels. Road traffic accidents are common, frequently occurring social disasters with high mortality rates, high residual disability rates, and large overall losses. With the development o...
