Friday Transportation Seminars at Portland State University have been a tradition since 2000. You can join us online at 11:30 AM. All presentations are recorded and shared on the event page afterwards.
This presentation provides a framework for improving older pedestrian safety in regard to serious (fatal and incapacitating) crashes, using Oregon as a case study. Upon review of state and federal practices pertaining to older pedestrian safety, four years of crash data identified 112 older (≥ 65 years) pedestrian serious injury crashes. These data were explored for factors that might be addressed systemically using two methods. First, raw frequencies in the crash data were assessed to determine trends and crash-related factors that are overrepresented. Second, a random forest analysis is conducted to determine important variables for predicting older pedestrian serious injury crashes. Using these crash-related factors, a workshop was held with 18 local stakeholders and experts. As part of the workshop, key crash trends, potential causations, and potential countermeasures by priority of implementation were determined based on perspectives from workshop participants. Three key systemic solutions were identified to improve older pedestrian safety, including improving pedestrian visibility and illumination, implementing treatments for left-turns, and shortening pedestrian crossing distances across the state. The framework presented in the current study can be adopted by other agencies to systemically address a wide variety of safety concerns.
This research was presented at the 2022 annual meeting of the Transportation Research Board (TRB), in the "Translating Safety Research to Real-World Solutions" session.
KEY LEARNING OUTCOMES
- A framework for improving older pedestrian safety.
- Complementing traditional safety analyses with machine learning approaches.
- Stakeholder and expert opinions on older pedestrian overrepresentations and potential solutions.
- Systemic solutions that can address older pedestrian safety, while also addressing safety for all pedestrians.
