Method and apparatus for publishing real-time traffic state in snowy days

Abstract

The present invention provides a method and an apparatus for publishing a real-time traffic state in snowy days. The method is designed for two conditions as follows: for the road monitored by cameras, the snow cover state of the road can be acquired through a video monitoring system, if the road is covered with snow, a road snow cover state is published, if the road is not covered with snow, a congestion state of the road is published according to a probe car system; for the road without camera, whether the road is covered with snow is judged according to a machine learning method, if the road is covered with snow, the road snow cover state is published, if the road is not covered with snow, the congestion state of the road is published according to the probe car system. Different from a conventional method for publishing a traffic state, the method of the invention can publish the congestion state and the snow cover state of the road at the same time, especially for the road without camera, the present invention puts forward the scheme which utilizes the machine learning method to obtain the snow cover state of the road and publishes the snow cover state to the public.

Description

technical field [0001] The present invention relates to the field of traffic status information publishing, in particular to a real-time traffic status publishing method in snowy weather and a traffic status publishing device, which can simultaneously release road congestion status and snow status, thereby effectively helping drivers avoid snow-covered roads Or warn the driver in advance. Background technique [0002] Floating car (ProbeCar), also known as "probe car", usually refers to a vehicle (such as a taxi, bus, etc.) with positioning and wireless communication devices, which can exchange information with the traffic information center. Floating car system (ProbeCar System) refers to a new type of traffic information system that communicates with the traffic information center in real time through a certain proportion of floating vehicles in the traffic flow. It generally consists of three parts: on-board equipment, wireless communication network and data processing ce...

Problems solved by technology

[0007] However, the method disclosed in Patent Document 1 has the following problems: first, from the content point of view, the problem of camera coverage is ignored, only road sections covered by cameras are considered, and road sections without camera coverage are ignored; Under the weather conditions, only the traffic jam status is released, but the snow status of the road is not released
