Road traffic parameter checking device and method thereof

Abstract

A kind of road traffic parameter determination device and determination method, it belongs to road traffic parameter collection field. A road traffic parameter determination device, includes vehicle real time monitor system which is composed of GPS vehicle monitor terminal GMT and monitor center MC, its characteristic is that: there is a GIS electron map linked with the vehicle real time monitor system, GIS electron map saves the real road information, sets electron enclosure in the wanted determine area in the GIS electron map. A road traffic parameter determination device, first judges whether the vehicle enter the first electron enclosure according to the gained data, if it has entered, the counter adds one, then determines the next data, to see whether there is new car entered, and then determines whether the car enters the second electron enclosure area, according to the data of the two electron enclosure area, calculates the road traffic parameter, gains the traffic state of the road. The date in this invention is real time, the range is large, and it is correct.

Description

technical field [0001] The invention belongs to the field of road traffic parameter collection, in particular to a device and method for collecting road traffic parameters by using a GPS terminal. Background technique [0002] At present, the main methods that can collect traffic parameters are: methods based on induction coils, methods using vehicle electronic tags, and more traditional methods based on video detection, infrared detection and microwave detection. However, most of these methods need to invest a lot of hardware facilities, and more importantly, the coverage is limited to a certain extent, and the real-time collection of traffic parameters cannot be realized. [0003] With the development of the global positioning system (GPS) technology application, more and more vehicles have installed the GPS positioning system. These vehicles then become probe vehicles that can collect road traffic parameters. The use of GPS to collect road traffic parameters has the adv...

Problems solved by technology

[0006] 2. Can not rule out the impact of inbound and outbound

[0007] 3. The impact of bus stops and taxi stops cannot be ruled out

[0008] These shortcomings are the inherent shortcomings of the existing methods of using GPS to collect road traffic parameters. Using these methods reduces the accuracy of road traffic parameter collection and cannot completely and accurately reflect the actual traffic status of the road.
