Traffic flow integrated and distributed analytic system based on license plate identification data and processing method thereof

Abstract

The invention relates to a traffic flow integrated and distributed analytic system based on license plate identification data, which comprises a roadside data acquisition subsystem, a roadside communication subsystem and a license plate identification and acquisition treatment platform subsystem. The processing method comprises the following steps: firstly, storing and uploading flow rate information and vehicle information which are acquired from license plate identification sections of external fields; secondly, secondarily cleaning license plates which are acquired from the external fields and cannot be identified and identifying the license plates again; thirdly, tracking and updating vehicle paths which are acquired by the traffic flow integrated and distributed analytic system based on the license plate identification data; fourthly, recording integrated or distributed bicycle trip paths; fifthly, calculating the number of vehicle paths in a road network, wherein the vehicle paths accord with the specified vehicle type and have same integrated sections or distributed sections and the time of the vehicles passing through the integrated sections or the distributed sections is in the same period; sixthly, correcting the flow rate of various integrated and distributed paths; and seventhly, using dynamic graphics to display the traffic flow distribution data of regional integrated and distributed paths.

Description

Technical field: [0001] The invention relates to the field of intelligent transportation, in particular to a traffic flow collection and distribution analysis system based on license plate recognition data and a processing method thereof, belonging to the technical field of intelligent transportation. Background technique: [0002] Urban traffic congestion is one of the problems faced by countries all over the world. The method of alleviating traffic congestion has shifted from simple road infrastructure construction to both infrastructure construction and traffic management. [0003] However, the traditional traffic management methods only start from the phenomenon of traffic congestion, which is often "healing the head when the head hurts and treating the foot when the foot hurts". . Traffic flow collection and distribution analysis refers to the analysis of vehicle travel paths on the road network to grasp the evolution of traffic flow in a designated area from various s...
