Comparing Traffic Safety Risks Across Transportation Modes

This research project compares traffic safety risks across different transportation modes. Very few studies have quantified crash risk across modes, especially recently in the United States. First, this study will calculate and compare mode-specific crash rates, using data from Utah and potentially elsewhere. Second, these mode-specific crash rates will be adjusted for key traffic safety risk factors, about the locations where and times when crashes take place, and the people who are involved. Finally, this work will propose a research-informed framework and analytical methods for improved comparisons of traffic safety risks across transportation modes, especially considering the contexts, factors, and mechanisms of crash causation. Overall, this research will generate useful traffic safety performance measures to help with prioritizing transportation safety investments and communicating safety risks to the public.
