Description
Technical field
The present invention relates to Vehicle Detection technical field, more particularly to a kind of arithmetic for real-time traffic flow based on Computerized three-dimensional scene
Detect early warning system.
Background technology
According to statistics, highway in China toll on traffic accounts for 73% or more of whole road fatalities,
Road traffic accident more than primary dead 3 people plays 85% or more that number accounts for total number, traffic accidents death toll
The ratio for accounting for total death toll is in the trend risen year by year, the main artery network traffic safety being made of high-grade highway in recent years
Situation very severe.To find out its cause, due to grasping not comprehensive, assurance inaccuracy to area road network traffic safety situation information,
Lack perfect traffic safety situation Warning Service system, the Working Measures specific aim for actively preventing traffic accident is poor, and reply is certainly
The abnormal emergency traffic command system such as right disaster, emergent traffic incident is not perfect, and the configuration of traffic safety emergency resources is poor.
Although currently, positive exploration has been done in terms of traffic safety situation early warning technology by China, its majority is ground
Study carefully the discussion of the single index or several indexs just for traffic safety situation, cannot it is many-sided on the whole, multi-level,
It is multifactor to illustrate the traffic safety situation general status of road network, and the warning grade criteria for classifying to traffic safety situation and
Method, which lacks, wants objective fact basis and effective theoretical method, most subjective initiatives for still relying on researchers and
Experiential fact divides traffic safety situation warning grade, because be unable to really objectively, accurately predict road
The various aspects of traffic safety state and trend.
