Research On Planning And Designing Of Healthy City Major Road Network System

Reasonable road network planning can effectively guide urban space to the direction ofhealthy and system to develop, In the face of the current urban traffic problem, we shouldreflect the original planning concept. The city road network connect main area and take on thecity most of the traffic, it's the very important part city road network. Therefore, in the urbanroad network planning process, we introduce the concept of health and provide a newinterpretation for city road network planning and design as the goal of the city's overallhealthy development.First, this paper reviews and summarizes the ancient, modern urban road networkdevelopment process and the characteristics,and review our country city road networkplanning and design problems, this paper analyzes the transformation of the economic systemfor the impact of the road use model, the current network planning specific problems includeland layout and the city road network planning of disorders, dry dry city road network functionforms, mixed and section highly channelizing intersection design, etc. According to the historyand present situation, this paper revisites the city road network planning and design on thecombination with concept of healthSecond, Basing on the road network planning design mode of criticism, lead health cityroad network planning and design of the key characteristics, summarize domestic and foreignroads classification. Bases on the health concept of roads classification, and gives the functionpositioning.Again, analysis the urban form evolution, research on the health of the city urban form oncombined with the relationship of traffic mode and urban form types, present land use andtransport planning coordination strategy; Summary of road network layout and influencingfactors of layout types on unifying the domestic and foreign research on urban road. Analyzesthe main factors that should be considered reasonable density, And suggest more reasonablethe value of road network density. Last,study urban center and residential area road planningmethod.Finally, research cross section design on combining cross-sectional element on the basis ofproposing the principle of major road space resources distribution. According to the capacitymatching and different traffic flow running place, sduty intersection design,and research thespecial method of cross section design.
