Traffic information processing method, equipment and system

Abstract

The invention provides a traffic information processing method, traffic information processing equipment and a traffic information processing system. The traffic information processing method comprises that a base station receives at least two position request messages transmitted by at least one vehicle-mounted terminal; for each vehicle-mounted terminal, the base station determines first longitude and latitude information of the vehicle-mounted terminal according to the first position request message, determines second longitude and latitude information of the vehicle-mounted terminal according to the second position request message, and generates driving speed information according to first time information, second time information, the first longitude and latitude information and the second longitude and latitude information, and a terminal identifier, the first time information, the second time information, the first longitude and latitude information, the second longitude and latitude information and the driving speed information form vehicle information corresponding to the vehicle-mounted vehicle; and the base station transmits the vehicle information of at least one vehicle-mounted terminal to a vehicle position information server. According to the traffic information processing method, the traffic information processing equipment and the traffic information processing system, the traffic information is acquired, and the accuracy and the rationality of traffic early-warning are improved.

Description

technical field [0001] The present invention relates to communication technology, in particular to a traffic information processing method, equipment and system. Background technique [0002] In recent years, with the continuous development of society, the number of automobiles has continued to increase, and road congestion has become more and more serious. In order to improve the traffic performance of the existing road network, it is necessary to collect traffic information of each road section in the road network and carry out traffic analysis. Early warning and traffic flow control. [0003] In the prior art, the traffic information of each road section is obtained mainly by installing cameras on each road section, but this method of erecting cameras based on intersections is relatively expensive, difficult to maintain, and greatly affected by weather conditions. When there is no camera installed at the intersection, or the weather conditions are poor, the visibility is...
