Analysis of Bike and Pedestrian Crashes and Their Contributing Factors in Idaho

Crash typing is the process of analyzing crash details to categorize crashes into similar groups, which can help identify hotspots, rising problems, and deploy the most effective countermeasures. This research analyzed crashes involving motor vehicles and bicycles or pedestrians in Idaho between 2012 and 2021. Using the PBCAT2 methodology, with supplementary machine learning tools, the study reviewed 2,739 bicycle and 2,209 pedestrian crash records. Findings indicate a decline in bicyclist crashes, but a steady rate in pedestrian crashes with a notable rise in fatalities, particularly in specific scenarios such as near parking lots. Key risk factors include motorist speeding, midblock crossings for bicyclists, and pedestrians walking on roads. The study suggests countermeasures such as expanded bicycle facilities, enhanced lighting, and stricter law enforcement to improve safety for vulnerable road users in Idaho.
