Road condition information sharing system

Abstract

The invention discloses a road condition information sharing system. The road condition information sharing system comprises positioning devices, prompting terminals, wireless communication devices, and a cloud server. The positioning devices are used to detect own position information in a real-time manner, and are used to transmit the position information to the cloud server in a real-time manner. The prompting terminals are used to transmit query requests to the cloud server, and are used to prompt received matching information. The cloud server is used to receive the position information transmitted by various vehicles periodically, and is used to determine weights of various road segments according to a position frequency relation, and then the congestion degrees of the various road segments are determined, and are transmitted to the prompting terminals of the corresponding vehicles according to the query requests transmitted by the prompting terminals. The position frequency relation is as follows: weight=IF*IDF=1*log(N / n+0.01)=log(N / n+0.01), and n is a number of the position information received in specific road segments, and N is the number of the position information received in the corresponding position areas of the specific road segments. The road condition information sharing system is used to reflect the congestion degrees of the road segments accurately, and the user is conveniently aware of the congestion degree, and can estimate congestion time conveniently, and therefore user experience is good, and convenience performance is strong.

Description

technical field [0001] The invention relates to the technical field of vehicle data interaction, in particular to a road condition information sharing system. Background technique [0002] With the development of science and technology, cars are becoming more and more popular, and the congestion caused by the increase in the number of cars has become increasingly serious. [0003] In the process of driving at high speed, once there is a traffic jam, it will often be blocked for a long distance, such as several kilometers or even more than ten kilometers. The image analysis can only simply determine whether there is congestion on the road section, but it cannot accurately analyze the degree of congestion. Drivers cannot make a more accurate estimate of the time of traffic jams, which brings troubles to many drivers and is not convenient enough. [0004] Therefore, how to provide a more convenient road condition information sharing system is a problem that those skilled in th...
