Running information based road condition management method and system

Abstract

The invention discloses a running information based road condition management method and system. The method comprises the following steps of: (1) acquiring geographic position, speed, acceleration and distance with a front vehicle of a vehicle which encounters a road condition; (2) packaging the acquired geographic position, speed, acceleration and distance with the front vehicle and transmittingto a road condition management center; and (3) acquiring a semantic map position of the vehicle by the road condition management center according to the received geographic position, and acquiring a traffic jam condition of the current semantic map position according to the received speed, acceleration and distance with the front vehicle. The system comprises a vehicle road condition reporting unit (1) arranged on the vehicle and a master control unit (2) used for road condition management. The method and the system have the advantages of capability of conveniently acquiring the traffic jam condition of the semantic map position, small data quantity, accuracy and reliability.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a road condition management method and system for automatically collecting, generating, reporting and viewing vehicle road condition information. Background technique [0002] With the continuous development of automobile transportation, various vehicle road condition monitoring systems are becoming more and more common and extensive. The existing road condition systems can monitor traffic flow and road busy conditions to help traffic management and scheduling, but the existing road condition detection systems The obtained data is relatively single, often only contains GPS location information, which is very unintuitive, and multiple information is also independent of each other, unable to perform comprehensive error correction, analysis and situational reasoning, and automatically report hypermedia information; at the same time, users cannot participate in In ...

[0002] With the continuous development of automobile transportation, various vehicle road condition monitoring systems are becoming more and more common and extensive. The existing road condition systems can monitor traffic flow and road busy conditions to help traffic management and scheduling, but the existing road condition detection systems The obtained data is relatively single, often only contains GPS location information, which is very unintuitive, and multiple information is also independent of each other, unable to perform comprehensive error correction, analysis and situational reasoning, and automatically report hypermedia information; at the same time, users cannot participate in In the road condition monitoring system, actively report the information around the current vehicle

Although users can report real-time road conditions to the radio station through the phone, the operation of the phone report is inconvenient, and it is impossible to report immediately

In addition, the existing road condition detection and user reporting system is only for simple traffic management, not combined with emergency incident handling, not connected with hospitals, road maintenance and other relevant departments, and cannot meet the needs of real-time monitoring and reporting of road condition accidents
