Abstract:Existing walking and biking data are often insufficient to support active transportation planning activities. This study utilized an emerging large-scale human mobility dataset to identify places with a higher number of short-distance trips to non-residential locations. These locations are more likely to be served by active modes of transportation, given adequate infrastructure and network connectivity. Demographic variables (i.e., population density and poverty level) were weaved into the mobility index design to prioritize access for more people and address equity concerns. In addition, a safety index, which takes into account the number of injurious crashes involving pedestrians and bicyclists, and a connectivity index, which reflects the density of existing active transportation infrastructure, were also calculated. These indices were considered alongside the mobility index while generating an active transportation investment potential score. The scores are statewide standardized values, where a higher score indicates a greater need for safety improvement (i.e., more injuries/fatalities), greater mobility needs (i.e., more short-distance trips), and lower network density (i.e., inhibiting current demand). All the indices and scores were generated at both the grid level (in 0.1 km^2) and the segment level (in 0.1-mile).
