Example Embodiment

[0025] like figure 1 As shown, the implementation steps of the road condition management method based on driving information in the embodiment of the present invention are as follows:

[0026] 1) Collect the geographic location, speed, acceleration and distance from the vehicle in front of the vehicle encountered in road conditions;

[0027] 2) Pack the collected geographical location, speed, acceleration and distance from the vehicle in front and send it to the road condition management center through the wireless network;

[0028] 3) The road condition management center obtains the semantic map position of the vehicle according to the received geographic location, and obtains the traffic jam situation at the current semantic map position according to the received speed, acceleration and distance from the vehicle in front.

[0029] Encountered road conditions refer to accidents related to vehicle traffic information such as traffic jams, traffic accidents, traffic control, a...

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 ...
