Mobile traffic flow statistics device and method based on wireless signal scanning technology

Abstract

The invention discloses a mobile traffic flow statistics device and method based on a wireless signal scanning technology. The mobile traffic flow statistics device comprises a detection mechanism which includs a wireless signal detector and a host connected with the wireless signal detector, wherein the wireless signal detector is used for detecting the wireless terminal on the traffic road section; a map of the detected traffic road segment is stored in the host, and the wireless signal detector marks the position of the detected wireless terminal on a map. The mobile traffic flow statisticsdevice also comprises an analysis mechanism, which comprises a measurement module and a processing module which are connected with each other, wherein the measuring module and the processing module are connected with the host respectively, and the measuring module measures the distance between the marking points on the map, and sends the mark points with the distance value smaller than the distance threshold value to the processing module; the processing module combines several mark points into one mark point, and the mark points are replaced by the mark points so as to form a traffic flow statistical graph. The invention is advantageous in that the device is simple, and the investment is low; all traffic road sections can be comprehensively covered, and comprehensive statistics on the traffic flow can be realized.

Description

technical field [0001] The invention relates to the technical field of application of wireless signal scanning technology, in particular to a mobile traffic flow statistics device and method based on wireless signal scanning technology. Background technique [0002] Traffic flow refers to the number of traffic entities passing through a certain point, a certain section or a certain lane of a road within a certain period of time. With the construction of transportation infrastructure and the development of intelligent transportation systems, traffic planning and traffic guidance have become a research hotspot in the field of transportation. For traffic planning and traffic guidance, accurate traffic flow prediction is the premise and key to its realization. [0003] Traffic flow statistics play a very important role in the construction of smart cities. Traffic flow statistics are the infrastructure of smart cities. Traditional traffic flow statistics devices such as video ...

AI Technical Summary

Problems solved by technology

However, due to the different physical conditions such as the length of road sections and the number of lanes, the collection scheme of this collection method is bound to be overly complicated, and the investment and maintenance of collection equipment, as well as system upgrades and management are complex and massive.

And due to system upgrading and management and the limitation of the cost of the equipment itself, these traffic flow statistics devices are generally only installed on the main roads, which can only reflect the traffic flow of the installed road sections, and there is a lack of flow statistics devices for branch roads. Therefore, there is an urgent need for a device with low input cost, easy installation and maintenance, and accurate statistical data.
