Traffic accident diagnosis in the last decade - a case study

Accident reduction projects must undergo the research stage of the current situation and trends based on a historical record of accidents. Identification of hot spots for accidents is a vital step in safety management, since roadway improvements are supposed to be applied to random locations. In this context we present a diagnosis of the traffic accidents in the Cidade Industrial de Curitiba, CIC (Brazil), and to identify several measures that could contribute to the reduction of accidents. We take advantage of GIS and exploratory analysis to identify road accident hot spots both visually and statistically. Finally, some guidelines are suggested, using 10 years of data in a case study.
