Assessing Changes in Accessibility and Its Impact on Rent-Burdened Households

The purpose of this paper is to analyze the relationship between affordable housing and transit by looking at how system redesigns affect accessibility to destinations. The premise is that improved accessibility to jobs and key destinations (social services, medical, dental, etc.) lowers transportation costs for households, improving the affordability of cites. This is a case-study analysis of three transit systems who have conducted a major redesign of their transit system. It uses ArcGIS Network Analysis to assess changes in travel time to jobs and key services for rent-burdened individuals and affordable housing residents. The results are stratified by travel time and percent of income paid towards rent to show the number of destinations that are available within a 30-minute walking distance of a bus stop. The analysis showed that including a coverage-based component to the route design preserve access to these individuals and the improved accessibility leads to increases in ridership, leading to lower transportation costs. This study, however, does not quantify the change in travel behavior towards using transit post route redesign as a means to explain potential household savings. The next steps would be to look more closely at affordable housing communities and rent-burdened individuals in one of the cities and survey the individuals to see if the route changes led to them using transit more and how it is affecting their household budget. Further explaining this relationship would provide cities additional tools to address affordable housing needs in their communities.
