Crash frequency statistical model for rural roads : evaluating private public partnership rehabilitation projects in developing countries

"In Colombia, road accidents are the second cause of violent deaths. Due to accidents in 2016 45,256 persons were injured and 7,280 killed. 41% of this deaths were on rural roads and there is a current trend of increasing accidents. This paper investigates factors that affect crash frequency in rural highways roads. A statistical model was developed in non-urban areas and for a developing country. This model relates crash frequency during a 4-year period (2013-2016) occurred on a specific rural road of Colombia divided into 403 segments. The factors investigated were horizontal alignment, operational characteristics, cross-sectional alignment, geometric design, lateral environment, and pavement conditions. Seven count-data model were compared with an ordered logit model, in order to explore the best fit for the road analyzed." -- Tomado del Formato de Documento de Grado.
