The Influence of the Infrastructure Characteristics in Urban Road Accidents Occurrence

This paper summarizes the result of a study which contributes to the improvement of road safety in Portuguese urban areas, through the creation of tools that can be used in intervention methods in the planning and management of road networks. The first tool relates the creation of a geocoded database of road accidents that occurred in Lisbon between 2004 and 2007, which allowed the definition of digital maps, with the possibility of a wide range of consultations and crossing of information. The second tool concerns the development of models to estimate the frequency of accidents on urban networks, according to different desegregations: road element (intersections and segments); type of accident (accidents with and without pedestrians); and inclusion of explanatory variables related to the road environment. Several methods were used to assess the goodness of fit of the developed models, allowing more robust conclusions.
