Embodiment 1

[0038] The road condition real-time evaluation system consists of many smart phone accessories and smart phone groups equipped on mobile vehicles, and a remote cloud computing platform. Smartphone accessories include a camera for shooting the front / rear road, a digital processor, and a data memory. The data memory stores lane line detection and tracking, vehicle detection and tracking, pedestrian detection and tracking, traffic sign detection and recognition, and traffic signal light detection and recognition programs. The smart phone accessory transmits the extracted surrounding road condition information and the location confidence and speed information of the vehicle to the smart phone platform, and then sends the information to the cloud computing platform through the mobile phone application software.

[0039] The remote cloud computing platform obtains the information from the smartphone group and evaluates the smoothness of a certain road. When there are few lane lines ...

Embodiment 2

[0042] The road condition real-time evaluation system is composed of many active safety components equipped on mobile vehicles, entertainment communication components and remote cloud computing platforms. Active safety components can be composed of one or more combinations of millimeter-wave radar, visual camera sensor, far-infrared thermal imaging sensor and ultrasonic sensor.

[0043] The active safety components obtain the position and speed information of surrounding vehicles and pedestrians, and send these information to the remote cloud computing platform through the entertainment communication components. The remote cloud computing platform obtains the surrounding environment perception information from the scattered vehicles, and evaluates the smoothness of a certain road. When the speed of the vehicle and the detected vehicles in the surrounding area are both fast, increase the smoothness observation value of the road section, and vice versa; Observation; when the su...

Abstract

The invention provides a real-time evaluation system for road conditions, and the system is characterized in that the system comprises a plurality of traffic monitoring devices which are used for obtaining the position and speed information of vehicles and the information of surrounding road conditions of the vehicles; a wireless communication module which is used for the wireless transmission of the information obtained by the traffic monitoring devices; and an aggregation terminal module which carries out aggregation according to the information transmitted by the wireless transmission module, and obtains an unobstructive evaluation value of road conditions. The system is advantageous in that a road condition induction device for safe driving detection of a vehicle is applied in the system; the information of the surrounding road conditions of the vehicle is used as parameters for evaluating the unobstructive condition of a road; the system greatly enlarges the evaluation area, improves the evaluation precision, is low in implementation cost, and is easy to popularize.

Description

technical field [0001] The patent of the present invention relates to the field of intelligent transportation, in particular to a system and method for real-time evaluation of road conditions arranged on normal road vehicles. Background technique [0002] The real-time status of road traffic is important information for social production and personal travel. Through government infrastructure investment, data collection nodes are set up in important traffic areas, and then aggregated and analyzed. Now the transportation department can obtain real-time traffic information of some road sections, but this method requires a lot of capital and manpower, and is highly dependent on individual key nodes. Once a node fails, the monitoring of the corresponding road section will be interrupted; and it is difficult to achieve All roads are fully covered. [0003] Another method for estimating the real-time road conditions is to obtain the user's geographic location and movement informa...
