Project Summary
This project is a continuation of a CSET Year-1 project at the University of Idaho titled “Documenting the Characteristics of Traffic Crashes for RITI Communities in Idaho”. The project represents the second step in establishing an in-depth understanding of the traffic safety conditions in RITI communities towards the ultimate goal of improving safety for these underserved groups through research, education, and outreach activities. The Year-1 project, currently underway, has three objectives: 1) identify and document different sources of crash data for RITI communities in Idaho, 2) conduct an in-depth crash analysis to document the characteristics of traffic crashes in RITI communities in Idaho, and 3) identify and document different sources for traffic exposure data (vehicle-miles-travelled) for RITI communities in Idaho. In this project we aim to achieve the following three objectives:
1) Develop a methodology to estimate Average Annual Daily Traffic (AADT) on rural roads based on available traffic counts and on “potential network flow” between origins and destinations;
2) Use AADT and other exposure measure data to document crash rates for different roadway segments in RITI communities in Idaho; and
3) Synthesize and document possible engineering and education intervention measures to reduce the number and severity of crashes for RITI communities in Idaho.
