Study On Daily Activity And Travel Behavior Of Public Housing Residents

Research on the daily activities and travel choices of the residents in large public housing communities,one of the vulnerable groups in urban areas,has been a hot topic in urban sociology and geography,and has become one of the important ways to reveal the differentiation of urban social spaces and the reconstruction of the urban spatial structure.By reviewing the theories related to large public housing communities and the daily activities and travel choices of the residents,we constructed a theoretical framework for interpreting residents’ daily activities and travel choices.Using this framework,we studied four cases of large public housing communities in Nanjing to probe into the time-space characteristics and travel mechanism of residents’ daily activities,identify and assess their "living circle," and summarize and evaluate the main problems and causes of the "living circle" in such communities,and proposed feasible optimization strategies.Construction of the theoretical framework for interpreting the daily activities and travel choices of residents in large public housing communities.First,we selected the theories closely related to this study for summarization and reference purposes.Second,we used the above theories to extract three core elements,i.e.,time,space and intra-household labor division,and developed combinations of these elements.Finally,we elaborated on the residents’ daily activities and travel choice process at different layers,and generated a preliminary theoretical framework to interpret daily activities and travel choices of residents in large public housing communities with four layers,i.e.,activity and travel demand(demand layer),intra-household labor division(labor division layer),combinations and priorities of intra-household labor division(configuration layer),and time-space response of activities and travel choices(response layer).We selected four cases of large public housing communities in Nanjing to empirically analyze the daily activities and travel choices process of residents based on their activity log data from four aspects,i.e.,daily activities(time-space characteristics and time-space agglomeration characteristics),travel choices(travel routes and mechanism),theoretical interpretations,and optimization strategies.The characteristics of the residents’ daily activities in large public housing communities are derived mainly from two aspects:the time-space characteristics and the time-space agglomeration.With regard to the time-space characteristics of daily activities,first,we summarized the general time-space patterns of the daily activities of the group from the perspective of intra-household labor division;second,we clustered and extracted typical cases from them,and classified and analyzed the time-space characteristics of activities coupled with intra-household labor division;and finally,we discussed the factors that affect the time-space differentiation of daily activities in the mode of intra-household labor division.With regard to the time-space agglomeration characteristics of daily activities,based on the perspective of intra-household labor division,first,we developed a time-space autocorrelation function by learning from the spatial autocorrelation model;second,we depicted the general time-space agglomeration characteristics of the daily activities of residents in large public housing communities from two perspectives,i.e.,main urban area and residential area,and compared and analyzed the time-space agglomeration characteristics of different groups and activities;and finally,we summarized the response patterns of "time-family" and"space-family" in different communities,groups,and activities.The daily travel choices of residents in large public housing communities are mainly derived from two aspects:route and mechanism.With regard to daily travel routes,first,we summarized and analyzed three travel characteristics of five groups using the time-space path method of time geography and then classified and merged these travel characteristics to conduct the "multi-scenario" analysis on multiple travel routes for different groups;second,based on the constraint model,we compared and explained the restriction pattern of daily travel choices and the decision-making mechanism of multiple routes for residents in such communities;and finally,we summarized the response patterns of "time-family" and "space-family" of multi-route travels for different groups.With regard to the daily travel mechanism,first,we constructed a hypothesis model for the impacts of individual family attributes,existing environments,and intra-household labor division on residents’ daily travel choices;second,we verified the fitting degree of the model through multiple steps and revealed the mediating effect of the intra-household labor division model;and finally,we analyzed the differences between influencing mechanisms for different groups and different travel choices(time and space of three travel characteristics).Theoretical interpretation for daily activities and travel choices of residents in large public housing communities.First,we corrected the initial theoretical framework to generate a revised framework to theoretically interpret the daily activities and travel behaviors of residents in large public housing communities;second,from the perspective of "time-space-family" interaction,we deduced,interpreted,and refined the daily activities and travel behaviors of the group;and finally,we proposed an appropriate roadmap for constructing "ideal living circles."Optimization strategies for large public housing communities.Based on the roadmap for constructing"ideal living circles"for large public housing communities,first,we selected four large public housing communities as empirical cases to identify their "living circles," second,we evaluated and analyzed the living environments of these"living circles" in two dimensions,i.e.,single factor and overall,and finally,we summarized and segregated the main problems faced by the "living circles" of such communities and their causes,proposed feasible optimization strategies and suggestions,and abstracted and constructed a"ideal living circle" model for such communities.In this study,by comparing different groups in large public housing communities,as well as their activities,travel choices,and interactions,emphasizing the coupling of daily activities and travel choices and the conjugation of time-space,and incorporating the "intra-household labor division" element,we revealed the time-space characteristics and internal mechanism of the daily activities and travel choices of residents in large public housing communities.This study has practical significance and theoretical value,and provides academic thinkers an inspiration for the construction of harmonious societies and communities and "ideal living circles" in the context of new urbanization.
