Study On The Optimization Design System For Urban Road Reconstruction Project

The existing city road reconstruction project is often used as a way to improve traffic conditions,implementation of the reconstruction project of city road according to the traffic demand forecast,demand forecast can only do a feasibility study and follow-up work,however,for the demand forecast of city road reconstruction project is not enough attention,the traditional method is according to the design method of the general road demand forecast,but the transformation of the city road traffic will cause the re organization and distribution area,so we cannot copy the traditional demand forecasting method,so the research on demand forecast of city road reconstruction project is very important.Around the above problems,the proposed optimization design system for city road reconstruction project,which mainly studies the traffic demand prediction and optimization design of the two part,for the city road reconstruction project forecasting method is proposed based on the analysis of demand,and demand forecast to determine the optimal design method.Based on the characteristics of road road reconstruction project to determine the scope of the study of city road reconstruction project;second is to determine the method of obtaining OD distribution status data,based on the OD distribution data,TransCAD platform to create a network and community model based on the work to do the preliminary data preparation for demand forecasting;finally,based on demand forecast analysis on road reconstruction engineering system optimization design,according to the demand forecasting results were quantitatively analyzed on road conditions,so that the problem and solve the problem found in advance,the system within the scope of the research of network optimized design,and puts forward the traffic management measures supporting the optimization of continuous transformation through the basic points and lines to improve face.This system makes the optimization design improves not only the transformation of the road itself capacity at the same time,optimization and management measures of the system canreduce the negative effects brought by the road reconstruction project,the transformation of the road and the surrounding road network traffic state can be relatively smooth.
