This data page provides details about the performance measure related to High Severity Traffic Crashes as well as access to the data sets and any supplemental data. The Engineering and Transportation Department uses this data to improve safety in Tempe.
This data includes vehicle/vehicle, vehicle/bicycle and vehicle/pedestrian crashes in Tempe. The data also includes the type of crash and location. This layer is used in the related Vision Zero story map, web maps and operations dashboard.
