Developing a Data-Driven Safety Assessment Framework for RITI Communities in Washington State

Rural, Isolated, Tribal, or Indigenous (RITI) communities across the United States are disadvantaged from a transportation safety perspective. Particular concern is focusing on rural road safety. Official data from Federal Highway Administration (FHWA) shows that, in 2012, 54 percent of all fatalities occurred on rural roads while only 19 percent of the US population lived in rural communities. The fatality rate was 2.4 times higher in rural areas than in urban areas (1.81 and 0.74, respectively). Since RITI communities often do not have the capability and resources to sufficiently solve roadway safety problems, several challenges are encountered for addressing transportation safety issues in RITI communities, including: (1) Crashes are often randomly distributed on local and rural roads in RITI areas; (2) Strategies to address safety issues are diverse for different RITI communities and draw from several safety areas. As a result, there is a critical need to realize equitably-augmented safety solutions that address the needs of these underserved and underinvested RITI communities. A survey made by National Association of Counties (NACo) in 2009 revealed that only 42 percent of counties surveyed maintained a database that tracks the number and types of crashes on their rural roads and slightly under half of the respondents have conducted a road safety audit. Till recently, existing databases are still incomplete for most of the RITI communities. It is necessary to develop a complete safety database system for RITI communities. The aim of this research is to conduct a two-year project to build up an effective safety database platform to facilitate data partitioning and visualization for each RITI community in the first year (Phase I) and develop a data-driven safety assessment framework based on the safety database platform to enable effective roadway safety management for RITI communities in Washington State in the second year (Phase II).
