Embodiment Construction
[0039] The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are illustrated.
[0040] figure 1 It is a schematic diagram of an embodiment of the method for collecting road condition information in the present invention. like figure 1 As shown, the steps of the method for collecting road condition information in this embodiment are as follows:
[0041] In step 101, the driving information of the vehicle is obtained in real time through the vehicle bus.
[0042] Step 102, acquiring GPS position data of the global positioning system in real time.
[0043] Step 103, combining the GPS position data acquired at the same time with the driving information of the vehicle to generate road condition information.
[0044] Step 104: Send the traffic condition information to the traffic condition analysis server according to a predetermined time interval, so that the traffic condition ...

The present invention discloses a method and a system for analyzing road condition information, a vehicle-mounted terminal and a road condition analysis server. The method for analyzing the road condition information comprises the steps of receiving the road condition information sent by the vehicle-mounted terminal according to a predetermined time interval, wherein the vehicle-mounted terminal obtains the driving information of a vehicle real-timely via a vehicle bus; real-timely obtaining the position data of a global position system (GPS), and combining the position data of the GPS and the driving information of the vehicle which are obtained at the same time to generate the road condition information; carrying out map matching according to the position data of the GPS to determine the road section in which the vehicle is located; and determining the road condition of the road section in which the vehicle is located according to the driving information of the vehicle. The driving information of the vehicle is obtained via the vehicle bus instead of a GPS signal, so that the real-time driving status of the vehicle still can be obtained accurately on the condition that the quality of the GPS signal can not be guaranteed, and the road condition is conducive to being determined accurately.
Description
technical field [0001] The invention relates to the communication field, in particular to a method and system for analyzing road condition information, a vehicle-mounted terminal and a road condition analysis server. Background technique [0002] In order to effectively obtain road condition information in order to realize intelligent traffic control, the following two methods are currently used to collect road condition information: [0003] 1. Acquire vehicle flow and speed by laying road induction coils on the side of the road for road condition information analysis. [0004] 2. Adopt GPS (Global Position System, Global Positioning System) floating car method, regularly obtain vehicle position information and vehicle speed through GPS information, match the GPS information with the electronic map, calculate the average speed of the vehicle in certain road sections, and analyze the road conditions. [0005] Among them, in the first method, since road induction coils need ...
