Research On Fast Detection Method For Pedestrian Network Based On The Analysis Of Pedestrian Behavior Characteristics

With the rapid development of the national economy for many years,the national life material level,mobile traffic has gradually become one of the most important domestic transportation transportation development idea of the vast majority of domestic city is built in motor traffic in car oriented priority to the development of the basic principle,this mode of development has brought a series of problems in the city.At present,domestic and foreign scholars have reached a consensus that: to promote the development of pedestrian traffic is the key to alleviate this problem a series of city.As the space carrier of walking activity,walking network plays a decisive role in promoting the development of walking network.Therefore,it is of great significance to start with the behavioral characteristics of walker,to study and analyze the walking network,and to construct the pedestrian network which is the most suitable for pedestrian behavior characteristics.The ultimate goal of this study is to build a set of practical application of the rapid detection of the network-optimization method.At present,there are three types of quantitative research methods of urban network space,which are based on geometric analysis,topological analysis and reachability analysis.However,the basis of the three studies is based on the urban traffic network or slow network,the lack of specific characteristics of pedestrian behavior or walking network characteristics.At the same time that the three methods represent three of pedestrian network perspective,the academics lack of the combination of the three methods,so that the comprehensive analysis ability of network characteristics is poor,even if there is a combining way,but almost all the time,manpower and technology into this requirement is too large and difficult to use in the actual project.So the basic direction of the research in determining: specifically for pedestrian behavior and pedestrian network characteristics,construction of a fast quantitative description method,to make precise study of pedestrian network,found that walking and walking network interaction behavior characteristics,through the transformation of pedestrian network optimization,make the network with walking the behavior of people,and ultimately to promote pedestrian travel.First of all,the pedestrian behavior characteristics were systematically combing,found the pedestrian behavior characteristics and relationship between pedestrian network forms,and these relations ultimately correspond to three research pedestrian network perspective: geometry,topology,accessibility perspective.Starting from the above three perspectives,the objective behavior and the overall research combining walking values oriented(such as: rapid research,accurate analysis),and exploratory study of the logical derivation,the perspective for pedestrian network corresponding quantitative indexes and its specific formula.Finally,combining the three perspectives,a set of quantitative description index system for pedestrian network is presented.Through the comparative study on the case of Tokyo,Chengdu City,Asakusa Gulangyu Islet of Xiamen City,the completion of the index value meaning of the deduction,we can make the numerical indexes related to interpretation of the size,to judge the people walking behavior in some walking within the network(e.g.,is easy to distinguish whether obvious detour direction).Then,because of Dayan ancient town in Lijiang pedestrian network with network is complete and relatively independent,not affected by vehicle interference,network formed by the spontaneous,visibility and influence of the big advantages,this paper selects the Dayan ancient town as an empirical case study.Through empirical research on case analysis,quantitative description not only proves the reliability and scientific system,but also dig out more about regular walking and walking network behavior,network flow and peripheral function formats,degree of relationship.To further improve the quantitative description of the walking network,so that we can predict more and more comprehensive pedestrian movement in a pedestrian network by the index value.Through the analysis of the empirical case,as well as a more profound understanding of the quantitative description system of the walking network,the paper designs a universal design strategy of multiple optimal walking networks.Finally,combined with the design strategy,a set of fast detection and optimization method is proposed,which is based on the characteristics of walking network and walking behavior.Finally,the pedestrian network optimization project as an example of Guiyang city of Nanming river area,rapid detection-pedestrian network optimization method as the guidance for the reconstruction of the former pedestrian network conducted a quantitative detection,quickly find out the defect of regional pedestrian network.According to the actual situation of Nanming river area,this paper puts forward the specific network optimization design strategy,and makes a comparative test on the optimized walking network.The results show that the walking network is improved obviously,and the whole operation time is controlled within 8 hours.It shows that the fast detection optimization method has practical value.
