Research On Layout And Optimization Of Urban Road Network

Entering the21st century, with the deepening of reform and opening up, the socialand economic development rapidly, urbanization and motorization process intohigh-speed development period, whether the urban space layout, traffic characteristics,or residents’ activity way and the way to travel, great changes have taken place. Theoriginal can not meet the demand of normal traffic layout of road network planning,led to increasing urban traffic congestion, traffic accident rates to rise and a series ofproblems, the process of historical development in China requires us to the theory andmethod of urban road network layout are innovation and breakthrough.Based on this severe situation, in this paper, the new method of urban roadnetwork layout and optimization work is studied. First study the urban road networkplanning layout of the status quo and advanced experience at home and abroad,summarizes the characteristics and classification of urban road, and then analyzes thelayout of the road network pattern and the relationship between urban landdevelopment; With support from the scientific theoretical basis, summarizes the urbanroad network evaluation indexes, determine the traffic prediction method and roadnetwork capacity calculation method, the application will be used in highway networkplanning in the node important degree method was improved, can make it is suitablefor the layout of urban road network. Urban road network layout optimization model isestablished, and finally to handan city CongTai area as an example is analyzed tovalidate and prove the rationality and applicability of the model, for the future of urbanroad network layout work provides a scientific basis and methods.Reasonable layout of road network planning, can effectively strengthen thefunction of network, improve the efficiency of transportation; Reducing waste ofmoney blindly blindly; At the same time to promote the city image, enhance theaesthetic feeling, make the person become a harmonious whole, vehicles, road, ensuresafe, smooth and convenient transportation system, to more rapid and orderlydevelopment of economic and social.
