Bicyclist injury severity in traffic crashes: A spatial approach for geo-referenced crash data to uncover non-stationary correlates

•The study uncovers non-stationary correlates of bicyclist injury severity in traffic crashes.•The modeling approach accounts for the spatial heterogeneity in traffic crashes.•The study explored geo-referenced bicycle-motor vehicle crashes in North Carolina.•Results show correlates of bicyclist injury severity vary substantially across North Carolina.•Modeling results can be used to localize bicycling safety countermeasures.
