Abstract

The study of the relationship between the built environment and road safety suggest there are associations between density and urban design features with traffic incidents. This paper conducts a quantitative data analysis with generalized ordinal logit models and log-linear regressions to estimate the influence of the built environment on road safety in Bogota and focuses on road crashes outcomes by estimating the influence of built environment attributes on fatalities and injured victims. The analysis was conducted with georeferenced road crashes data from 2012 to 2016 provided by the Secretariat of Mobility of Bogota. The quantitative data analysis was focused on arterial roads, Bus Rapid Transit (BRT) System corridors and stations in the city. This analysis was complemented with interviews on site. The results suggest that the presence of pedestrian bridges is positively associated with the number of road crashes. Special attention to road safety in the design of BRT terminals and accesses to stations is needed as the infrastructure might increase speeds and attract pedestrian demand.
