AB The research was focused in a multiple correspondence analysis. We analyzed therelationships between accident rates and road infrastructure variables in a municipality ofSoacha (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 Soachamunicipality the fatality rate is 10 deaths per 100.000 inhabitants. Soacha reports thehighest number of deaths in the region (ANSV, 2020). In this research we performed aspatial analysis using a Kernel density graph to identify the areas with the highestconcentration of fatal crashes.We found that five dimensions explain 70% of the variability of data. We made a crossdimensionanalysis by pairs, to obtain information on all possible combinations betweenthat dimensions and used them as an input of a spatial distribution analysis of crashes inthe municipality. We also calculated the contour curves for density modeling. We foundthat higher concentration of fatal crashes is around the highway “Autopista Sur”. Thesecrashes were associated whit crash hypothesis variables, immediate cause of the crash,crash class, crash severity and type of vehicle.
