Planning And Evaluation On Healthy Road Traffic System Of Old-city District

Old city zone is the most complex area for city traffic, traffic studies continued focus of attention at home and abroad, but also the difficulties in specific planning practice. In recent years, more and more cities proposed low carbon ecological, public transport priority, and other people-oriented concept in renewal of the old city zone, hoping to provide transportation support in building a healthy and orderly, vibrant, livable industry old city zone.Firstly, referring to the healthy city concept, put forward the concept of the old city zone healthy road traffic and try to through the analysis of the system characteristics of traffic roads at home and abroad to summarize the characteristics of the old city zone healthy road traffic, points out the common existing status of old city zone common problems of non health condition, and provides a basis for refining the core elements of the old city zone healthy road traffic.Secondly, systematically proposed the method of construction of the old city zone healthy road traffic system from the two levels of planning and design. From the planning level, it contains three aspects with the "high-density, small block" road network planning, full coverage of the public transport system planning, continuous slow traffic system planning. From the design level, it contains three aspects with traffic calming of motorized transport facilities design, humane slow traffic facilities design, and intelligent traffic management devices design.Then, the page focuses on the study on method and system of the evaluation on traffic healthy state of old city zone road. Integrated, choose the evaluate index on health importance, easy to quantify, easy to collect of old city zone road traffic state.Using a generalized linear model, and solving the generalized linear model cocfficicnts by AHP and expert decision-making method. The method can quickly evaluate the traffic healthy state of old city zone road.Finally, the paper takes the old city zone of Hefei City as an example. Through the analysis of the status of road traffic problems and health status evaluation, put forward the planning and design, evaluate it, and practice the main contents of the paper.
