Research On The Ideal Unit Design Of Green Network City Based On Slow Mode Transportation

After nearly a hundred years of development,it was found that cities that relied entirely on motor vehicle brought a series of problems such as traffic congestion,air pollution,disorderly expansion of urban boundaries,and neglected the most basic slow traffic to meet the needs of motor vehicle request.Therefore,the promotion of urban construction slow traffic priority calls are getting bigger and bigger,China also appeared a series of such as the Vine City,Green Network City and so on with the slow ideal urban planning and design theory.The so-called Green Network City is built in the city a certain width and urban road dislocation intertwined with the public green network and build the ideal city theory.Green network not only has the function of urban green space,but also combined with the use of green infrastructure(GI)and low impact development(LID)technology.This paper summarizes the characteristics of Green Network City complex and microcosmic.Based on the summary of other classical ideal cities,the scale of the ideal unit of the Green Network City is defined,and the ideal unit research category of 1KM2 size is determined.Then,the design research emphasizing the dominant position is carried out.First of all,the paper discusses the composition and demand basis of the slow-moving system,and puts forward that the urban design comprehensive means of slow-forward priority has reasonable slow-moving traffic layout,perfect slow-moving facilities and urban functions in line with the slow demand.Secondly,based on the mixed business plan which meets the requirements of slowmoving function,we plan to quantify the layout.Based on the relevant design specifications,we will study the layout of the ideal unit based on the slow line,the layout of the building,the green space and the sponge system,and form the ideal unit Planning and Design.Finally,the details of the design of the ideal unit,such as the path of the diversion of the vehicle,the construction of the entrance and elevation,the construction of the walking system and the shared bicycle system,and the details of the green street are discussed.Thus forming a research project based on the slow green grid city ideal unit.
