Study On The Traffic Impact Analysis Of The Large Cultural Building

Nowadays, along with economic development and social progress, the pace of urban development projects have been speed up, projects of construction or renovation make urban problem of transport become more complicated. How to forecast induced traffic of project from the relationship between land use and transport planning has become a large potential research direction in the city planning. GIS plays more and more important supplementary role in transport because of improvement of GIS. Therefore, GIS applied to the traffic impact analysis can coordinate the relation between land use and urban transport system more effectively.This paper has made a study of traffic impact analysis (TIA) about the large cultural building. On the basis of summarizing the way the existing research methods, traffic impact features of the large cultural building have been introduced, and the means of traffic impact analysis about the large cultural building has been put forward:the author used the threshold based on the scale of construction project to determine whether carry on traffic impact analysis; improved the existing research methods on the influence scope, gained the determination of traffic incidence based on location and the most trip distance; the traffic flow brought by the large cultural building has the features of "conglomeration" and "radiation", so the paper inosculated traffic distribution and traffic assignment, used the multi-path nonequilibrium assignment model based on path total impedance to assign the non-public flow to each line.The paper choose the large cultural buildings "tow halls and one odeum" of Changsha as object of study, visualized the data by uniting the software of GIS, applied the methods of TIA about large cultural building to analyse traffic impact. The impact of road and crossroad has been obtained, and improvement measures and proposals have been brought forward.The research findings possess the actual meaning, which can offer foundation of circumjacent transportation management and design of "tow halls and one odeum". At the same time, it has positive influence on the location of other large cultural building and the management of circumjacent transportation, furthermore, it shows that GIS can help governor solve the traffic problems efficiently.
