Summary

This study investigates factors influencing the injury severity of motor vehicle-pedestrian crashes in rural areas, specifically focusing on rural Connecticut. The research addresses the problem that while pedestrian crashes are rare in rural settings, they result in a higher fraction of fatalities compared to urban areas, largely due to higher vehicle speeds. Because collision speed is difficult to measure directly, the authors analyze roadway and area features that influence driver behavior and speed, thereby affecting injury outcomes. The methodology utilizes an ordered probit model to evaluate 278 pedestrian crashes occurring on state-maintained two-lane highways in Connecticut between 1989 and 1998. The dataset was restricted to crashes where pedestrians were crossing roads without traffic control (no stop signs or signals). Injury severity was coded using the KABCO scale (from no injury to fatality). The analysis controlled for human factors such as pedestrian and driver alcohol involvement, pedestrian age (65+), and vehicle type. Roadway variables included clear roadway width and the presence of on-street parking. Additionally, seven qualitative area types were defined based on building density, spacing, and proximity to the road, ranging from downtown to low-density residential. The results identified several significant predictors of injury severity. Vehicle type, driver alcohol involvement, pedestrian age 65 or older, and pedestrian alcohol involvement significantly increased severity. Clear roadway width also significantly influenced severity, with wider roads associated with higher injury risks. Conversely, on-street parking and speed limits were not found to be significant predictors in this specific rural context. The analysis of area types revealed that grouping the seven categories into two distinct groups significantly improved model prediction. One group, comprising downtown, compact residential, and commercial areas, experienced significantly lower injury severity. The second group, consisting of village, downtown fringe, and low-density residential areas, experienced higher injury severity. The authors suggest that drivers may travel at lower speeds in commercial areas due to driveways and attractions, whereas speeds remain higher in village and fringe areas. The significance of this study lies in its identification of specific roadway and environmental features that correlate with pedestrian injury severity in rural environments. By demonstrating that area type and clear roadway width are significant factors, the research provides evidence-based strategies for improving rural pedestrian safety. The findings suggest that interventions aimed at reducing vehicle speeds, such as modifying roadway geometry or managing land use patterns to create a "narrowing" effect, could mitigate injury severity. The study serves as a prototype for future research, highlighting the need for larger datasets to achieve higher statistical significance levels.

Key finding

Clear roadway width, vehicle type, driver alcohol involvement, pedestrian age 65 or older, and pedestrian alcohol involvement significantly influenced pedestrian injury severity, while area types grouped into two categories showed significantly different injury severity levels.
