| Abstract |
Walkability studies are usually area-based and have measured composite built environment attributes that affect walking behavior, usually at the local community or city level. These are helpful at a broader scale but do not provide "on-the ground" realistic estimation of actual accessibility as determined by the availability of pedestrian infrastructure. This study fills this important gap in estimating true pedestrian accessibility by introducing a preliminary methodological framework of network-based walkability analysis. Using the Atlanta BeltLine as a case study, we advance a more nuanced preliminary method that incorporates both quantitative and qualitative measures that might influence route choice for walkability. Factors included in the analysis were land use diversity, slope, crime and highway restrictions. Based on statistical techniques, these were incorporated into network analysis as costs. Our network-based approach can perform various analyses of walkability. Accessibility to transit stops was assessed using service area analysis as well as best route and closest station analyses based on existing roads with costs imposed. |
