Tempe High Severity Traffic Crash Records Through 2024

City of Tempe provides data on fatal and serious injury traffic crashes, including vehicle, bicycle, and pedestrian incidents. The dataset is used for the city's Vision Zero safety initiative and is updated semi-annually, with data complete through December 31, 2024. It includes crash type and location details.

Use Cases

• Analyze crash type frequency to identify patterns in vehicle, bicycle, and pedestrian incidents for targeted safety interventions.
• Map crash location data to identify high-risk intersections or corridors within Tempe.
• Use incident date and time data stored in Arizona time (UTC-07:00) to study temporal patterns of high-severity crashes.
• Support Vision Zero story maps and operations dashboards by providing the underlying crash severity and location data.

Strengths
