Info

Purpose: These maps display the regions within a city that can be accessed in less than an hour from its center, across varying transport modes

Brief Methodology: Population-weighted centroids were generated for the CT census level using centroids and population at the DA census level. Travel times were calculated from each city’s central location to the weighted centroids in each CT census level for each travel mode. All travel times above an hour are filtered out.
