Large Commercial Projects Traffic Impact Analysis Key Technical Research

Due to the large commercial projects will attract large traffic flow, so it is necessary to its neighboring network for traffic impact analysis, and shall conscientiously considered to predict future year growth in volume of traffic on proposed commercial projects bring huge influence to organize a good project surrounding network of transportation conditions.As is known to all, for urban transportation planning large-scale commercial projects for the core problem is flow prediction, and flow prediction based data from the city and travel demand. Therefore, the influence of traffic demand in four phases accurately predict will travel to the key research is one of the key technologies. In urban transportation generated forecast research, we see in western countries, the study started earlier also form the relatively perfect forecast system. And to generate domestic travel later start, the domestic demand is mainly copy foreign forecast method, usually in several very traditional and common methods to choose, but only when used in the common to take their differences in ignored, lack of different nature of the project classification prediction. In view of the current problems existing in China, based on the survey data traffic situation, the incomplete for large-scale commercial projects surrounding network traffic prediction that a type, meticulous description of the project of wanda plaza generated forecast of transportation.In the four phases of traffic analysis method, the first phase transportation demand, according to the needs, will travel distribution of cargoes to predict the network traffic distribution, so the traffic distribution in the entire traffic impact analysis plays a key role link. At times, the key techniques of domestic currently is mainly copied foreign trip distribution forecasting method, but for foreign specific how to use these methods, the method is suitable for domestic and foreign research aspects lack. And, due to the limited domestic conditions, many software and data conditions are not met, so urgent need for trip distribution forecasting with characteristics of research projects for various types of projects, the distribution of forecasting methods, to fully get accurate distribution information. Based on the theoretical method under the premise of joining, wanda plaza for example transportation project of applied research distribution forecasting method, using a dual gravity model distribution algorithm, and through the Transcad software calculated wanda plaza traffic impact of trip distribution results.This is based on the background and study for the similar large commercial projects, provide highly reference analysis of analysis template.
