Description
Technical field
The present invention relates to intelligent transportation system and car networking field, in particular it relates to which a kind of be based on DSRC
The congestion detection means and method of (DSRC, Dedicated Short Range Communications).
Background technology
With the rapid development of China's communication, vehicle guaranteeding organic quantity increases sharply, and China's road congestion conditions are particularly big
The road congestion conditions getting worse in city, pressure is more and more big to caused by urban traffic control.Congestion in road problem into
To restrict economic development, one of horizontal factor of people's lives happiness is reduced.
The method of traffic congestion detection at present mainly has：1. Coil Detector method, 2. Floating Car detection method, 3. video monitoring examine
Survey method.Coil detecting system needs to destroy pavement construction when installing, if carrying out, large-scale application cost is higher, and service life has
Limit, maintenance is carried out in high speed and replaces inconvenience.Floating car data is to be distributed in the dynamic vehicle position of city everywhere by obtaining
Information back is to data processing centre, then the heart carries out going deep into working process acquisition in data handling.Shortcoming is on city
The vehicle GPS passback dynamic location information of the taxi of ten thousand is too big to the cost of processing center, and the GPS of each car is believed
The accuracy requirement of the return data of breath is very high, operation inconvenience.It is right due to the raising of video resolution for video detection method
The requirement of image procossing is increased, and very big pressure is caused to processing system.In addition under the scene of highway, camera can
Detection is limited in scope, therefore in order to which effective detection congestion or other traffic accidents, the quantity of camera arrangement can become very more,
So as to cause the rising of testing cost.
It is CN104680819A through retrieval, such as China Patent Publication No., a kind of anti-congestion method of road of the invention and its is
System, including：Establish connection；Platform preset the first pickup area scope, the second pickup area scope, speed data collection time segment value,
The first boundary value of the gentle slow train speed of vehicle numerical value, unimpeded speed and slowly the second boundary value of speed and congestion speed；Detection
Judge speed and positional information, and speed and positional information are uploaded to platform；Detection of platform analyzes speed data collection time segment value
It is interior, the first car-mounted terminal numerical value through the first pickup area, the second car-mounted terminal numerical value through the second pickup area, and according to point
Result generation instruction is analysed, and judges road congestion conditions, and will be instructed and judged result is sent to and traffic lights end and vehicle-mounted end
End；Terminal shows road congestion conditions；Traffic lights end adjusts current direction according to the instruction.But will respectively it adopted in the patent
In collection region the information that gathers pass back platform cost it is too big, and the accuracy of the return data to the positional information of each car
It is it is required that very high.If the positional information passed back has error, platform generation error will be caused to instruct, aggravate congestion in road phenomenon.
