Pedestrians

This study investigates to what extent a mismatch between residential preferences and actual residential locations is associated with residents’ physical activity and walking. The residents of Montgomery County, MD, and Twin Cities, MN, were classified into four residential subgroups, and their walking and physical activity outcomes were compared. The results showed that, for transport activity and walking outcomes, participants living in a urban location and preferring a urban environment were more likely to be active than those who lived in a suburban location and preferred a...

We develop an agent-based model of utilitarian walking and use the model to explore spatial and socio-economic factors affecting adult utilitarian walking and how travel costs as well as various educational interventions aimed at changing attitudes can alter the prevalence of walking and income differentials in walking. The model is validated against US national data. We contrast realistic and extreme parameter values in our model and test effects of changing these parameters across various segregation and pricing scenarios while allowing for interactions between travel choice and...

Understanding how the built environment at a neighborhood scale is associated with individuals' walking has been a common research objective in public health and city planning. In contrast to the extant literature, we examine whether a neighborhood's location defined at a regional scale is associated with walking and whether this association is separately identifiable from the association of the neighborhood built environment and walking. The findings indicated that walking for commuting purposes was associated more strongly with neighborhood location than with the neighborhood built...

Injuries among pedestrians are a major public health concern in Colombian cities such as Cali. This is one of the first studies in Latin America to apply Bayesian maximum entropy (BME) methods to visualize and produce fine-scale, highly accurate estimates of citywide pedestrian fatalities. The purpose of this study is to determine the BME method that best estimates pedestrian mortality rates and reduces statistical noise. We further utilized BME methods to identify and differentiate spatial patterns and persistent versus transient pedestrian mortality hotspots. Methods: In this multiyear...
