These charts show the variations and crash occurrence trends in the MAG region, by year for the last ten years. The charts identify the total number of crashes, the number of persons injured, and the number of persons killed in each year. Separate charts are provided for all crashes, crashes involving motorized vehicles and bicyclists and crashes involving motorized vehicles and pedestrians.

Charts are also provided to show crash occurrence variation by month, day of week and by hour of day. These charts are based only on crashes in the most recent year. The final chart shows the collision manner for crashes in the most recent year.

The data source for this analysis is compiled police reports in the ADOT crash database. It should be noted that crashes are reported only if they involve a motorized vehicle, and result in death, injury or property damage worth $1000 or more. For example, a bicyclist accidentally running off a bike trail, hitting an object and being killed is not recorded as a crash because there was no motorized vehicle involved.
