Traffic Accidents

Roadways nationwide are the third leading cause of preventable death in the United States, behind intentional self-harm and non-transportation-related, accidental injuries. There are many contributors to roadway deaths including speed of traffic, interactions between different types of transportation like bicycles and motor vehicles, the design of the roadway, and vehicle safety equipment. Transportation planners have been working to improve the ability of roadways to safely accommodate different modes of travel in an effort to reduce fatalities and serious injuries.

Roadway fatalities and serious injuries are measured by: (1) ranking of Arizona traffic fatalities per 100 million vehicle miles travelled as compared to the 50 U.S. states and the District of Columbia; (2) Arizona injuries per 100 million vehicle miles travelled; and (3) raw number of fatalities and injuries for pedal cyclists, pedestrians, motorcyclists, and car crashes for local communities.

This metric is updated annually for the following localities:

  • National
  • States
