Abstract:

The shortage of direct measures of pedestrian risk exposure hampers efforts to identify safety needs and to improve pedestrian safety. This paper presents an exposure-based model of pedestrian safety and its application to identifying Indiana urban and rural townships with a high risk of pedestrian crashes. A negative binomial model was selected as suitable for this purpose. The presence of spatial autocorrelation was tested over the residuals of the developed models, and no significant autocorrelation was found. Estimation of the safety effect of the exposure variables in this study indicated a considerable difference between rural and urban areas as far as the strength of the same variables. The following variables were found to significantly affect pedestrian safety: jobs, population, intersections, road mileage, K-12 schools, and shopping centers. In addition, the number of vehicles per household and the number of days with precipitation were found to be significant as well. The developed safety performance function was used to identify Indiana townships with pedestrian safety needs. Many urban townships in Indiana experience a high number of pedestrian crashes. In most cases, the number of pedestrian crashes was explained by the large risk exposure. However, a number of rural townships exhibiting a small number of pedestrian crashes were identified as experiencing too many crashes for the risk exposure. A balanced approach to planning pedestrian safety improvements and budget allocations should consider both types of townships.
