Pavement condition information acquisition and release method

Abstract

The invention provides a pavement condition information acquisition and release method. Driving speed, driving direction, acceleration sensor data and position data of all vehicles driven on a monitored road segment are acquired in real time and uploaded to a cloud platform; the cloud platform compares the acquired real-time data with historical data of the corresponding period according to the road segment of the vehicles so that abnormal data are automatically identified; mode matching and clustering analysis are performed on the abnormal data; and when abnormal situations occur through judgment, information indicating the abnormal situations of the road condition is released to the vehicles passing the road segment position and the management department of the road segment. The beneficial effects of the pavement condition information acquisition and release method are that big data analysis is fully utilized, the road condition is judged through change of driving speed, driving direction and acceleration of the vehicles of the road segment, and the information indicating the abnormal situations of the road condition is released to the vehicles passing the road segment position and the management department so that the vehicles passing the road segment are enabled to timely avoid or divert, and the management department is enabled to timely discover abnormality of the road condition and perform timely processing.

Description

technical field [0001] The present invention relates to road condition information collection and release technology, in particular to a road surface condition information collection and release method. Background technique [0002] At present, road condition information cannot be obtained in time. Vehicles do not know the road condition when passing an unfamiliar road section. When they find potholes on the road ahead, uneven manhole covers or large-scale water accumulation, they often need to brake suddenly, which may easily cause safety accidents. Motor vehicle drivers do not know the road condition information, nor can they know the historical experience of vehicles passing through this road section in the past. Units and individuals responsible for managing and maintaining pavement infrastructure cannot timely and comprehensively understand relevant information. In the prior art, the collection of road surface condition information mainly relies on the driver's report ...
