Research On The Design Theory And Method Of Urban Road Cross-section

With the accelerated process of urbanization, the rapid development of the motor vehicle, and thepattern of urban space, living and work places from the unit compound type to the gradual separation of thespace, bringing the explosive growth of the city traffic, the transportation infrastructure in many cities areoverloaded,especially morning and evening peak period. Under the premise does not change the structureand layout of urban functions, you can optimize the allocation of the limited road resources, improve theefficiency of road traffic. As a direct carrier of traffic, the road cross-section has been designed using theexperience of value to be divided,not in-depth study of traffic content and various changes. This leads tothe road resources on the one hand the tension, on the other hand, there are wasteful. Through in-depthstudy of each part of the cross-sectional, exploring reasonable Combined mode of the cross-sectional, wecan get great significance not only for road transport and some guidance on the future design of roadcross-section.On the basis of analyzing the domestic and international road cross-section of the theoretical statusquo, as well as domestic practice, this paper firstly studied the traffic carrying land skeleton,communication space, disaster prevention and protection, municipal, vector, visual landscape, ecologicalprotection, seven function Aggregate road features of the road cross-section of each part of the influencingfactors. Communicating roads should meet the speedy passage of traffic flow, by road traffic forecastmethod,we can determine combination mode and part of the width of the road section. The life of the streetis designed to give the idea of people-centered, which is that the road section design considerations forcreating the life of the street. The road width of both sides of the building height, spatial relationships, slowtraffic integration Concept should run through them.By researching road cross-sectional design method, the cross-section of urban road design shouldconsider the seven basic functions, to achieve the organic integration of the roads and space and improvethe operating efficiency of the transport, provide guidance for planning and design of road cross-section.
