Project Summary

This project documents the characteristics of traffic crashes in RITI communities in Idaho and establishes an in-depth understanding of the baseline traffic safety conditions in RITI communities. This is an important first step towards the ultimate goal of improving safety for these underserved groups through research, education, and outreach activities. The project has the following three objectives: 1) identify and document different sources of crash data for RITI communities in Idaho, 2) conduct an in-depth five-year crash analysis (2012-2016) to document the characteristics of traffic crashes in RITI communities using the Idaho Transportation Department’s (ITD) WebCars crash data tool, and 3) identify and document different sources for traffic exposure data (vehicle-miles-travelled) for RITI communities in Idaho

The project activities will help enhance the understanding of the impact factors that affect rural traffic crash frequencies and severities, and how these factors vary over time and across regions. The project outcome will also help identify crash causation factors and effective countermeasures to crashes involving RITI communities. Data generated through this project will allow CSET researchers to measure the center’s performance and its overall contribution to RITI transportation safety and help aid and guide the state’s efforts to improve safety on Idaho’s RITI roadway network through the identification of effective crash countermeasures that have the highest possible return on investment for these communities.
