King County Connectivity Analysis Toolbox

Fehr & Peers provided technical expertise to King County Metro Transit and Sound Transit to improve non-motorized access within station areas. The study included a large data collection effort merging a number of jurisdiction-based datasets including land use, street networks, sidewalks, bike lanes, and traffic signals.

Based upon existing research on determinants of non-motorized transit demand, we developed a suite of GIS tools to automatically evaluate connectivity and estimate the change in transit ridership that would result from improved connectivity. The connectivity evaluation included route-directness, bicycling stress, walk and bike shed areas, and arterial crossing frequency. The connectivity evaluation and a number of demographic variables provided the basis for a regression-based analysis to understand the impact on pedestrian and bicycle demand from a variety of non-motorized projects. This allowed jurisdictions and the transit agencies to prioritize their infrastructure investments to realize the largest potential growth in bicycle and pedestrian access to transit.
