Tribal Motor Vehicle Crash Injury Prevention Project (TMVCIPP)

Vision Statement

The elimination of all unintentional motor vehicle crash injuries and fatalities among American Indians, on and off tribal lands, by addressing environmental, behavioral, and political factors that influence these events.

Mission Statement

To assist Tribes within the Phoenix and Tucson Indian Health Service Areas with building injury prevention program capacity by supporting the development of, or improvements to, infrastructure in surveillance, prevention, and evaluation information, for planning and motor vehicle crash and injury prevention policy decision making.


To build Tribally-driven motor vehicle crash injury prevention capacity within the Phoenix and Tucson Indian Health Service Areas, in order to improve American Indian health and well-being.

Reports & Presentations

Bike Traffic Skills Training
The presentation provides an overview of the four Bike Traffic Skills Courses conducted in mid-May and early June 2015 for Hualapai Tribe, Kaibab Band of Paiute Indians, Duckwater Shoshone Tribe, and Te-Moak Tribe of Western Shoshone children aged three to sixteen. The ITCA’s TEC continues to work at the intersection of transportation safety and health via ongoing support of tribal Safe Routes to School, Road Safety Assessment, and active living project implementation. Pooled resources from the Department of Health and Human Services Office of Minority Health, Hualapai Law Enforcement and Nevada Department of Transportation helped deliver the courses, bike maintenance, and bike helmet and bicycle safety accessory purchases.


Comparison of Motor Vehicle Crash Injuries, Fatalities, and Crash Circumstances On‐ and Off‐Tribal Lands In Arizona, 2007‐2014
This is the first analysis of Arizona Department of Transportation (ADOT) Accident Location Identification Surveillance System (ALISS) data that compared motor vehicle crashes (MVCs) on Tribal lands and off Tribal lands as two independent populations. MVCs that result in injuries and fatalities are disproportionately more likely to occur on Tribal lands in Arizona. Compared to all races in Arizona, the American Indian/ Alaskan Native (AI/AN) MVC age-adjusted mortality rate has been three times higher than the state rate from 1980 through 2010. Data from ADOT ALISS for years 2007-2014 were used in the analysis. MVCs were designated on Tribal lands or off Tribal lands using geocoding.


Nevada Preliminary Motor Vehicle Crash Data Analysis
The data analyzed for this report came from a request to the Nevada Department of Transportation (NDOT) by the Inter Tribal Council of Arizona, Inc. Tribal Epidemiology Center for all reports for motor vehicle crashes (MVCs) on the Tribal lands in Nevada (NV) that were filed by law enforcement from 2007 to 2014. The data analyzed for this report came from 399,178 reports for MVCs in NV. Location of the MVCs and assignment to Tribal lands areas were done by NDOT. The Tribal lands data was identified by Kimley-Horn for NDOT using ArcGIS.


FINAL-Tractor-Trailer-Crash-Presentation“Turning Data into Action: Truck Tractor Crashes on Tribal Lands in Arizona” was presented at the 2016 National Tribal Transportation Conference by staff working on the Tribal Motor Vehicle Crash Injury Prevention Project (TMVCIPP) for the Inter Tribal Council of Arizona, Tribal Epidemiology Center, and the Kaibab Band of Paiute Indians. From the beginning of the TMVCIPP, preventing crashes with commercial and heavy vehicles has been a priority. The Kaibab Indian Reservation is located in northwestern Arizona near the north rim of the Grand Canyon and other tourist destinations, such as Zion National Park, Lake Powell and Pipe Springs National Monument. The rural, two-lane State Route 389 provides the only western access to the Grand Canyon northern rim from Las Vegas and is also a northern freight route. Project staff provided an overview of how crash data was used to drive planning, and they presented two Road Safety Assessments conducted with the Arizona Department of Transportation, and Share the Road training delivered by the Arizona Department of Public Safety to educate government staff and youth on driving strategies near commercial vehicles.


FINAL_Tractor_Trailer_Crash_Analysis_in_AZ_2009-2013The Truck Tractor Crash Analysis presentation summarized MVC factors identified in the Truck Tractor Trailer Crash Analysis Report, and linked the MVC topic with the increase of current and future TTT traffic in Arizona.



FINAL_Truck_Tractor_Crash_Analysis_AZTruck Tractor Trailer Crash Analysis Report
Description: To examine the impact of truck tractor trailer (TTT) motor vehicle crashes (MVCs) that occurred on Tribal lands in Arizona, 2009-2013. The primary focus is to describe the burden of injury and fatality due to TTT MVCs and identify opportunities for interventions to reduce the burden of morbidity and mortality from TTT MVCs on Tribal lands in Arizona. The data included all reports of MVCs in Arizona that were filed by law enforcement with the ADOT from 2009 to 2013.
