Study On The Construction Of High Efficient Walking System In Jinshui District Of Zhengzhou City

In recent years,China’s urban development model has gradually changed from the incremental expansion of "car-oriented" to the connotation of "people-oriented"inventory,which brings a new development opportunity for urban walkability.Urban walking behavior is an important way for citizens to experience urban life,outdoor activities,health and fitness.Walking is not only the "first kilometer" for citizens to start a new day of urban life,but also the "last kilometer" for citizens to end the day of urban life.From the perspective of traffic and commuting,the pedestrian system complements the urban infrastructure and meets the safety and convenience of job-housing transition.From the perspective of spatial planning,the pedestrian system,as an urban greenway,reasonably controls and integrates the limited green space resources,and realizes the coordination between supply and demand of citizens’ demands for health and sports.From the perspective of urban intention,the pedestrian system is an important carrier of outdoor life,which realizes the relevance and accessibility of urban vitality points.The absence of walking behavior can increase the stress of commuting to slow traffic and car dealers,which can trigger traffic congestion and a host of urban problems.On the one hand,urban built-up area space,old infrastructure,high population density,transformation is difficult;On the other hand,the street features of the built-up area are the result of mutual influence,mutual choice and mutual attraction between the street space and the surrounding residents.Therefore,the site selection of pedestrian system and the reconstruction of street space should be based on the recognition and classification of street features.Today,more and more studies begin to use multi-source open data to explore the strength and weakness of spatial vitality characteristics,and then formulate corresponding planning and design strategies.These data objectively reflect the commuting destinations of citizens within a certain range.Therefore,on the basis of investigation,analysis and identification of spatial characteristics,integrated spatial planning based on urban open source data is an important way to improve urban livability in the era of stock development.Based on the built up area of jinshui district,zhengzhou city(hereinafter referred to as the "proper")as an example,combined with field investigation,based on ArcGIS platform to build proper situation road edge feature recognition method,the walking road safety,comfort,convenience and so on carries on the quantitative analysis index,using the factor analysis method to identify and calculate the main factors influencing data variance of four aspects;Urban road network data,building location and height data of Jinshui District and other multi-source open data are used to simulate urban road space after opening.Through the classification and sorting of urban POI data and the kernel density analysis,the agglomeration degree of eight types of urban business forms is obtained.After the superposition of equal weights,the space with high agglomeration degree of urban business forms is obtained.Compared with the current situation,it is found that the areas with high agglomeration degree of business forms are usually the areas where large commercial complexes appear.Through integration of local space syntax,choice of local degrees and through calculation,it is concluded that gold waterway and agriculture road between the municipal road is relatively uniform,is local integration across the region and the choice of local degrees highest part,illustrates the way to further improve the situation of pedestrian environment as well as the open part of the closed residential space can effectively improve the overall experience on foot of jinshui district;Taking travel degree as the scale value of potential energy accessibility,the potential energy accessibility of urban road space after opening is calculated and divided into 10 grades.The higher the grade,the higher the "site suitability" of this area is.On the basis of pedestrian system main content of three aspects:will work "residential area-station" as a commuter load-point,"residential area,the park green space" as a fitness club load-point,"residential area-forms to gather center" as a daily commuter load-point,combining with the urban land data to establish the cost grid,respectively to calculate the lowest cost path;Combined with the calculation of potential energy accessibility and cost path,the site selection of the built-up area walking system is designed to encourage the return of walking behavior and alleviate a series of urban diseases caused by high-density urban space,such as traffic congestion,environmental pollution and lack of green space resources.
