Cloud server for providing road condition information and device for displaying road condition information

Abstract

The invention aims to providea cloud server for providing road condition information and a device for displaying the road condition information. The cloud server comprises a receiving device, a resolver, an arithmetical device, a road condition informationgeneration device and a providing device, wherein the receiving device is used for receiving respective phased various-speed driving records of vehicles in real time; the resolver is used for resolving a block involved in each phased various-speed driving record; the arithmetical device is used for updating the degree of congestion of each block based on all currently received phased various-speed driving records involved in the block; after the updated degree of congestion of each block is acquired, the arithmetical device determines the degree of congestion of a road section based on the degree of congestion of blocks on two sides of the road section; the road condition informationgeneration device is used for generating the road condition information based on the degree of congestion of road sections; and the providing device is used for providing vehicles with the road condition information. According to the example embodiment of the invention, the resource cost of a terminal can be reduced, and the accuracy and timeliness of the road condition information can be improved simultaneously.

Description

technical field [0001] The present invention generally relates to the field of traffic communications. More specifically, it relates to a cloud server for providing road condition information and a method thereof, and a device and method for displaying a road condition map on a terminal in a vehicle. Background technique [0002] With the improvement of people's living standards, driving a vehicle to travel has become one of the main modes of transportation for people. If the driver can obtain road condition information while driving the vehicle, it will help the driver plan the driving route and improve driving efficiency, thereby alleviating traffic congestion. Currently, there are four main ways for drivers to obtain road condition information: [0003] 1. Receive road condition information released by the data center (for example, public platforms such as traffic control departments, radio stations, and WeChat) (for example, road condition descriptions reported by driv...

Problems solved by technology

[0007] Among them, the first way to obtain road condition information requires a large number of people to participate, consumes a lot of financial and material resources, and cannot guarantee the real-time performance of the acquired road condition information; the second way to obtain road condition information requires the server of the navigation software to keep in touch with the terminal The communication link to obtain GPS data in real time has a large resource overhead; the third way to obtain road condition information can only obtain the approximate road condition information of a certain area through historical road condition information, which is not real-time enough and has little reference value; the fourth way The way to obtain road condition information is a relatively cutting-edge way, using the sensing capabilities of sensor devices, but the current processing method is to match the real-time sensing data of sensor devices with road information, which also needs to be supplemented by accurate GPS information, resources high cost

[0008] To sum up, the existing way of obtaining road condition information has a large resource overhead, and cannot meet the needs of real-time and accuracy
