Traffic survey data collection and analysis application system for road network and its working method

Abstract

A highway network traffic investigation data acquisition and analysis application system is composed of a traffic dynamic information auto-acquisition unit and a monitoring unit, wherein the traffic dynamic information acquisition unit is connected with the monitoring unit in virtue of a data transmission network; the working method is divided into a highway network OD data generation unit, a highway network traffic demand analysis and prediction unit, a highway network traffic distribution and network evaluation unit, a highway network planning unit, a highway project feasibility research and post-evaluation unit and a highway network operation management unit. The highway network traffic investigation data acquisition and analysis application system has the advantages of: (1) real-time, accurate and objective acquisition of highway information; (2) displaying the acquired and analyzed traffic information in image form on GIS; (3) providing maintenance management decision and planning construction decision of highways with basic database and theory support; (4) proving the public with main data basis of travel and induction service; (5) comprehensively acquiring data, and effectively and rationally selecting the data information, thereby providing a scientific and standard traffic investigation report.

Description

(1) Technical field: [0001] The invention relates to a data collection and analysis system and its working method, in particular to a highway network traffic survey data collection and analysis application system and its working method. (two) background technology: [0002] With the rapid development of the economy and the further advancement of the urbanization process, road construction has also entered a stage of accelerated development. In order to adapt to this trend, at present, the scale of the road network continues to expand, and the road network structure and traffic patterns have undergone major changes. It is difficult for the existing traffic volume survey system to reflect the traffic volume level in the road network comprehensively, accurately and objectively. , characteristics and changing rules, especially, with the initial formation of the highway network, how to incorporate this part of important basic data into the traffic data of the entire highway netwo...
