Research On Optimization Method Of Pedestrian Traffic From Residential Areas To Key Attraction Points

The residential area is the starting point and gathering place of the urban traffic flow.It is also the material carrier of people's lives.It also carries at least 1/3 of the life time of each resident and plays an important role in urban land use.The large closed residential area hinders the connection between the residential area and the city,reduces the overall efficiency of the city's traffic operation,and also exacerbates the problem of residents' short-distance walking and bypassing.It is good to organize the residential road network and optimize the traffic environment.The benign development of the district.At present,relevant researches at home and abroad,there are not many quantitative analysis of residential road network organization,and it is still not perfect.Combined with actual case research,based on refined technology,based on road network organization-walking perspective,quantitative analysis of different domestic and foreign The case of residential area in the form of road network summarizes the typical problems of walking away from the key attraction points of the city,and proposes an optimization method for exploring the road network planning by exploring the optimization and improvement methods of Dalian spring water residential areas.Based on the theoretical discussion of the residential road network organization,from the three aspects of walking,walking to the city's key attraction points and residential road network,summarizing relevant research at home and abroad,and discovering that there are technical defects in the existing research,the defect The research data is biased,and the related research does not effectively reflect the diversity of the street system model in the road network organization,and does not effectively propose the detailed planning method and optimization method of the road network.From urban road network mode and residential area walking to urban key attraction point road network organization,analyze the four typical residential case cases in the slow system,land layout,transportation site layout,and the organization law in relation to the motor vehicle system,get the following experience: 1)Developed slow-moving system helps to create a good residential environment and enhance the attractiveness of slow traffic;2)Mixed functional layout is conducive to increase the vitality of residential areas and reduce unnecessary long distances Travel;3)Intensive continuous block road system,which can increase the radiation range of public transportation and increase the probability of using public transportation.Exploring the method of constructing refined models,introducing data collection,ArcGIS traffic network model,and methods of applying SPSS and ACCESS software to analyze and manage model data,and using this model to quantify the case of three settlements in Beijing,Amsterdam,and San Francisco,USA analysis.According to the type of travel destinations of residents,the key attraction points are summarized as bus stops,track sites,primary and secondary schools and commercial facilities.The refined model is used to simulate the path selection of each residential unit building from the walking point to the attraction point to obtain OD and high-density grid.Straight line distance,path distance,bypass distance,bypass coefficient,relative bypass coefficient,road network density under multiple radii,etc.Based on the graphical results and quantitative analysis of data,the typical problems of settlements from key attraction points are summarized..Finally,based on the typical problem of settlements,for the Dalian spring water residential area,the residential area is optimized by opening and closing the residential area and adjusting the road network,and the open residential area(mainly walking open)and road network optimization(adding continuous street roads)are found.The method of reducing the broken road and increasing the density of the road network can greatly reduce the walking distance of the residential area;combined with the optimization and improvement results of the Dalian spring water residential area,referring to the planning experience of four foreign typical cases,the residential area should be close.At the key attraction points,the optimization method of improving the density of the surrounding road network,the connection degree of the road network and reducing the barrier degree of the road network.
