Trip Distribution Models Optimization Research In Cluster City

In order to avoid “city disease” which caused by urbanization and motorization,many urban planning experts see cluster development as the solution. Cluster city usedispersive spatial structure, split traffic flow to each chlusters, and balance trafficdemand within clusters.The reduced interval traffic volume between clusters coulderelease traffic jam in city centre. The advantage of transport in cluster city graduallyrevealed, now city planners began to come from urban development patterns studytraffic problems, the form of cluster become to the main development mode.The urban spatial structure of cluster city changed urban morphology andinternal interaction compare to other cities.Which also leads the change of traffic flowand traffic characteristics, such as trip distributions.This article from the perspective of cluster spatial structure, comprehensiveanalysis urban traffic characteristics and the reasons, and sum up the main reasonwhich influence to the trip distribution in cluster city. And provide a theoreticalsupport and technical guidance to trip distribution mode. The main contents includethe following parts:From the perspective of cluster urban city characteristics, systematic reviewsand summarizes the related concepts of cluster city, and deeply analysis thespatial structure and traffic characteristics. Take Chongqing urban city assample, expound and prove the features of cluster city.From the perspective of space structure, choose urban morphology, andurban density, urban layout as the breakthrough point. And combine withresident trip survey data, analysis the spatial structure on the influence of tripdistribution.Summarize the traditional trip distribution models, and further comparativeanalysis of all kinds of model applicability and their advantages anddisadvantages, and analysis the adaptability of models to each cluster cities.Quantization the spatial structure on the influence of the trip distribution, andintroduction job live balance, supporting facilities perfect degree, tripdistribution probability three optimization factors; Select the trip distributionmode which specific suitable for cluster city, and through optimize factorand the model form combination, fixed trip distribution models, make its can objectively and real simulation of cluster cities trip distribution rule.
