DSRC-based real-time road condition information acquisition device, method, and transfer device and method

Abstract

The invention provides a DSRC-based real-time road condition information acquisition device, a method, and a transfer device and a method. The DSRC-based real-time road condition information acquisition device comprises an antenna, a first positioning module, a first processing module, and a first DSRC receiving and transmitting module, wherein the first positioning module is connected with the antenna for receiving position information of the DSRC-based real-time road condition information acquisition device via the antenna; the first processing module is connected with the first positioning module for processing the position information into a DSRC data packet; and the first DSRC receiving and transmitting module is connected with the first processing module and the antenna respectively for transmitting the DSRC data packet. As the vehicle reports self position information automatically in real time, the vehicle can be merged with the existing intelligent vehicle host to form Internet of Vehicles, automatic and real-time road condition acquisition is realized, position information of driving vehicles on a road between the vehicle and a base station and between the base station and a road condition center can be transmitted in real time, real-time, accurate and thorough road condition information can be acquired, and a basis is provided for realization of intelligent traffic such as planning of the intelligent road.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, and relates to a road condition collection device, in particular to a DSRC-based real-time road condition information collection device and method, as well as a transfer device and method. Background technique [0002] With the development of the automobile industry, the number of automobiles continues to increase. Road congestion has also become a common phenomenon in traffic, which has had a great impact on economic and social development, and has become a major chronic disease that hinders the rapid and healthy development of traffic. A large part of my country's urban road congestion is the congestion of urban expressways, and the navigation routes given by traffic navigation maps are also urban expressways and expressways, which makes most of the vehicles that rely on map navigation flock to these recommended roads, causing congestion . However, for ordinary roads in the ...
