Analysis Of The Chengdu Chongqing Expressway Interchange To Bishan Qinglong Lake Connecting Traffic Line Project

In this paper,the theory and method of traffic volume forecast,such as traffic generation forecasting model,traffic distribution forecasting model,traffic assignment forecasting model and solving method,are comprehensively applied in this paper.The theory and method of traffic volume forecast are used in Chongqing Bishan City To Qinglonghu connecting line construction project traffic volume to predict.Based on the survey results and combined with the route plan and historical observation statistics,the survey of other modes of transport related lines,the base year OD table,and analysis of the regional main trunk line Road observation of the characteristics of the site traffic and the project channel traffic and other modes of transport-related traffic lines.The results of the study provide theoretical basis for determining the prospective traffic volume,road type,construction technical grade,project scale,economic evaluation and project decision-making,etc.,And provide scientific basis for the improvement of traffic planning and construction projects.Decision-making laid the foundation.Based on practical engineering problems,this paper deeply analyzes and studies the traffic forecasting method in the feasibility study of highway construction projects.It is expected to provide a scientific,reasonable and feasible method for the feasibility study of the construction project of the connecting line(including urban road)Of the traffic prediction method.
