Modeling the choice of walking based on household survey data

In Colombia, urban transport planning studies do not always include the modeling of pedestrian travel, particularly to study the choice of walking. This paper reports the results of research to model the choice of walking in an urban context, based on household survey data. The purpose of this research is to demonstrate how household surveys can be used to study the choice of traveling by foot in a city. Data from surveys conducted in two Colombian cities (Barrancabermeja and Cajica) are used. With the information available it was possible to estimate choice models of travel by foot, being also possible to identify the attributes that affect the decision to travel on foot. The study results indicate that the probability of walking decreases as travel time increases. Also, more cars and more income mean less chance of walking. Instead, the probability of walking increases for young people and family groups larger.
