Context: Pedestrian fatalities account for a disproportionate number of overall traffic fatalities. In 2009, 12.1% of all traffic fatalities nationwide were pedestrian fatalities. Research on how the built environment can minimize pedestrian injury is essential to creating safe communities and promoting active lifestyles. Objective: To identify characteristics of the built environment associated with pedestrian-motor vehicle collision (PMVC) locations along primary arterials. Study Population: Clark County, Washington PMVCs, 2007-2009. Methods: Retrospective sampling and logistic regression analysis allowed comparison of characteristics of the built environment surrounding PMVC locations to comparable locations without nearby collisions. Results: Locations on primary arterials with greater average monthly transit utilization (boardings and alightings) had significantly greater odds of having a nearby collision (OR = 1.24, 95% CI: 1.06-1.43 for 10,000 passenger increase per month). Areas with sidewalks, high-traffic volume intersections, and supermarkets were also associated with collision locations. Walkability of the surrounding environment was not predictive of PMVC locations in the multivariate model. Conclusion: Areas on primary arterials near highly utilized transit stops have more PMVCs. After adjustment, transit stops with lower walkability scores did not have more PMVCs, although overmatching may have masked a possible association. Future research should gather prospective data on pedestrian activity and look to areas with greater variation in walkability score.
