Study On Urban Bicycle Traffic System

China is a country where the bicycles are the most commonly used vehicles. After the period from rapid increase to stable development, the bicycle transport tends to be saturated at present. In this period, the most conspicuous character is that compared with other transport moods, bicycling comprises a considerable proportion in the urban traffic system. The situation of the urban bicycle transport in our country results from the specific social and economic conditions and the interaction of the inner and outer factors in urban transportation system under the circumstance of urban traffic development. In different situations and different environments, the actualities of urban traffic largely depend on the results of competition among various transport moods. With the improvement of living standard, the automated traffic of urban residents grows quickly, and a great amount of badly ordered bicycle traffic and rapidly emerged automobiles result in a severely interfered and mixed traffic flow. The interference of bicycles in automobiles has become a mail factor of urban road congestions. Consequently, the resolution of urban traffic problems hinges on successfully coping with urban bicycle traffic problems.Based on the actuality and tendency of the urban traffic in our country, the main content of this paper is groping for the principles of logical development of urban economy and living environment, as well as putting forward the appropriate developing strategies of urban bicycle traffic according to several facets such as city dimensions, different social and economical development phases, urban ground utilizing patterns and characters of city zones. Moreover, on the basis of the technology of dividing automobile and non-automobile traffic in the intersections, the bicycle traffic flow theory and the traffic control and management theory, the optimizing theory and applicative technologies to organize, design and control bicycle traffic is brought forward.
