AB Different studies over the past 30 years have shown an increase in the rates of crashfrequencies during road construction time, but this trend is not reported as valid for all cities.A question is raised whether higher rates are observed in arterial roads in Bogotá, Colombia.It is possible to apply descriptive statistics and hypothesis tests to prove them and identifythe variables that affect the accident rate during road construction. Our research aims toverify the incidence of high impact construction zones, in the crash rate at the arterial roadnetwork of Bogotá. We use descriptive statistics and inferential statistical tests to analyzewhether crash rates are statistically higher during construction time than during nonconstructiontime at the same highway sections considering different crash severities(damages-only, injuries, and fatalities). Our database considered 871 road links that makeup 68 artery corridors for the city of Bogota, and 5.450 road construction zones, from 2015to 2019. An analysis by corridor was performed, in which we identified seven patterns in thebehavior of accident rates influenced by the presence of a road intervention in the corridor.Within the patterns, it was evident that some corridors reported an increase in the accidentrate during the time of construction, while others showed a decrease in the same comparison.We used the Wilcoxon test to establish the statistical significance of our conclusions, with asignificance level of 10%. We also found that those construction interventions that do notrequire excavation of more than half a meter there was a decrease in the accident severity,as damages-only crashes, diminished during the construction time, while for thoseinterventions that include excavation greater than half a meter there was an increase inoverall accident rates during construction time.
