Research On The Integrated Re-use Of Overpass Accessary Space In Beijing

With the accelerating urbanization, the contradiction between urban traffic and urban space development and problems emerge in endlessly, so traffic space and the concept of urban public space composite use around the world to advocate, accessibility of urban public space and comfort and the efficiency of urban traffic influence and restrict each other, the design of interlinked between also become urgent and necessary.As the the product of moblization of1920s, city overpass has grown with urbanization and urban space evolution in the rapid development of large and medium-sized cities in our country. In functional service of motor vehicle traffic at the same time, its great effects on the urban space and urban life has significant exposure. Environmental problems, space utilization efficiency, dynamic and static traffic conversion, walking accessibility problems, urban space recognition issues involving many aspects of urban design and field, solve the existing problems and contradictions, overpasses and affiliated space exploring its reuse strategy, is no longer a single technical problems of single subject, but a composite technology and the value of a comprehensive topic.The characteristic of the urban traffic structure and urban spatial structure in Beijing determines the distribution, scale and spatial characteristics of the overpass system. Beijing has gone into moblization society since the end of the20th century, facing increasingly serious problem of urban traffic, environment. Urban outer space quality has become the core issue for residents. In such urban development background, with a large Numbers of overpass, whether Beijing can reverse the original function of a single, negative attributes of overpass space, actively using the existing resources conditions of colleges and universities create humanized and friendly city quality space will be the core challenges of this research.Accessary space through the intersection and the research of the integration of urban public space in ensuring overpass service smoothly under the condition of motor vehicle traffic safety, to make full use of the overpass accessary space, to achieve maximum comprehensive benefit; Strengthen walking activity and walking space continuity and friendly; Improve the ecological environment of the overpass accessary space, series overall urban ecological system, and then to the present situation of the city overpass negative accessary space into a high quality to provide according to the concept of urban public space, and maneuverability of the theoretical basis of the reference design strategy.
