Estimation of Pedestrian Volume Using Geospatial and Traffic Conflict Data

Walking is widely promoted in the U.S. with known benefits for personal health, the environment, and economic activity. This project investigated the association between pedestrian volume and pedestrian-vehicle interactions on crosswalks. Pedestrian-vehicle interactions were classified based on their severity following a modified version of the Swedish Traffic Conflict Technique. The severity of interactions on crosswalks was categorized using conflict ratio, the ratio of highly severe interactions to less severe interactions. A random-effects log-linear regression model was developed using conflict ratio, the ratio of highly severe interactions to less severe interactions, as a covariate along with other geospatial variables such as land use and network connectivity. The results indicate that the conflict ratio significantly explains variation in pedestrian volume at the studied crosswalk locations. Locations with higher conflict ratios have lower pedestrian volumes than locations with lower conflict ratios. Facilities that reduce the severity of pedestrian interaction more comfortable for pedestrians and can help planners to achieve their environmental, societal, and economical goals by promoting walking.
