Forigua, Julio Lyons, Liliana 2022-09-22T07:25:08Z 2022-09-22T07:25:08Z 2021-07 978-84-18465-12-3 http://hdl.handle.net/10259/7007 10.36443/10259/7007 The research was focused in a multiple correspondence analysis. We analyzed the relationships between accident rates and road infrastructure variables in a municipality of Soacha (with more than five hundred thousand inhabitants in the suburbs of Bogota- Colombia). In Colombia, the fatality rate is 13 deaths per 100.000 inhabitants. In Soacha municipality the fatality rate is 10 deaths per 100.000 inhabitants. Soacha reports the highest number of deaths in the region (ANSV, 2020). In this research we performed a spatial analysis using a Kernel density graph to identify the areas with the highest concentration of fatal crashes. We found that five dimensions explain 70% of the variability of data. We made a crossdimension analysis by pairs, to obtain information on all possible combinations between that dimensions and used them as an input of a spatial distribution analysis of crashes in the municipality. We also calculated the contour curves for density modeling. We found that higher concentration of fatal crashes is around the highway “Autopista Sur”. These crashes were associated whit crash hypothesis variables, immediate cause of the crash, crash class, crash severity and type of vehicle. eng info:eu-repo/semantics/openAccess Seguridad Infraestructuras Accidentes Safety Infrastructures Accidents Safety and road infrastructure: A spatial analysis in suburbs of Bogotá info:eu-repo/semantics/conferenceObject
