In the related art, in order to acquire the road condition information, the terminal with the positioning system usually reports its own positioning information to a particular central server through the network of operator, and the particular central server processes the collected information reported by a large number of terminals and then sends the road condition information in the area selected by the terminal to the terminal.
There is the following insufficient in the method for acquiring the road condition information:
firstly, it needs to set up the central server for processing, and the data bulk is big, the system is complicated and the maintenance is difficult;
secondly, it needs to cover the cost for using the network of mobile operator, and it cannot work normally when the network signal of the mobile operator is not good or the network fails; because the system needs to interact with the base station of the mobile operator, the viability and the capability to resist damage are poor; it is difficult for the navigation systems interacting with different operators to perform the interaction with each other;
thirdly, influenced by the processing capacity of the central server and the network congestion situation, it is apt to have a larger delay and it cannot perform the accurate real-time navigation for road condition, and it cannot prevent and avoid the emergence of the traffic accident.
