Example Embodiment

[0064] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0065] like figure 1 A schematic diagram of a typical case of device operation is shown. 1 in the figure is the installation position of the device on the vehicle, which is generally installed on the front windshield of the vehicle; 2 is the vehicle driving on the left side; 3 is the vehicle driving directly ahead; 4 is the vehicle driving on the right side. During the driving process of the vehicle, the vehicles driving on lane 1, lane 2, and lane 3 are detected in real time, and if there is a driving vehicle, parameters such as its driving speed are obtained in real time.

[0066] like figure 2 , image 3 As shown, the vehicle-mounted monomer road traffic state discrimination device includes a box body, and a traffic GIS module, a video traffic flow acquisition module (embedded camera), a video traffic flow analysis and processing module, and a tr...

Abstract

The invention discloses a vehicle-mounted single road traffic state distinguishing device. A traffic GIS module, a video traffic flow collection module, a video traffic flow analyzing and processing module, a traffic state distinguishing fuzzy reasoning module and a database system module are arranged in a box body; the video traffic flow collection module collects traffic flow video data in front of the collection module, the left side and the right side and transmits the traffic flow video data to the video traffic flow analyzing and processing module; the video traffic flow analyzing and processing module analyzes the video data output by the video traffic flow collection module, and corresponding traffic flow parameters are analyzed and obtained with a video image processing algorithm; the traffic state distinguishing fuzzy reasoning module establishes a traffic state distinguishing rule base to determine a reasoning mechanism according to the traffic flow and road net parameters; the GIS module can realize functions including planning of a traveler travel route, storing of road physical parameters and displaying of a real-time road traffic state; the database system module mainly stores road net historical traffic flow parameters and a traffic status value. The invention further discloses a method using the device.

Description

technical field [0001] The invention belongs to traffic transportation engineering technology, and in particular relates to road traffic state discrimination and prediction technology, vehicle navigation traffic information induction technology, especially a vehicle-mounted single road traffic state discrimination device and method. Background technique [0002] With the rapid development of my country's social economy, the per capita living standard has been greatly improved, and the number of cars per capita has increased year by year. The limited road resources are difficult to meet the growing demand for traffic travel, and traffic congestion has increased people's travel costs. Obtaining the traffic status of the road network in real time, and then dynamically selecting the best travel route, has become a powerful measure for travelers to shorten travel time and reduce travel costs. [0003] The Chinese invention patent application number is CN201110069317, which disclos...
