Trabajo presentado en: R-Evolucionando el transporte, XIV Congreso de Ingeniería del Transporte (CIT 2021), realizado en modalidad online los días 6, 7 y 8 de julio de 2021, organizado por la Universidad de Burgos
Different studies over the past 30 years have shown an increase in the rates of crash
frequencies 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 identify
the variables that affect the accident rate during road construction. Our research aims to
verify the incidence of high impact construction zones, in the crash rate at the arterial road
network of Bogotá. We use descriptive statistics and inferential statistical tests to analyze
whether crash rates are statistically higher during construction time than during nonconstruction
time at the same highway sections considering different crash severities
(damages-only, injuries, and fatalities). Our database considered 871 road links that make
up 68 artery corridors for the city of Bogota, and 5.450 road construction zones, from 2015
to 2019. An analysis by corridor was performed, in which we identified seven patterns in the
behavior 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 accident
rate 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 a
significance level of 10%. We also found that those construction interventions that do not
require 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 those
interventions that include excavation greater than half a meter there was an increase in
overall accident rates during construction time.
The research group wishes to thank the engineering faculty of the Universidad Nacional de Colombia, more specifically to the Vice-Dean of Research and Extension, which through the call for Support to Research Seedbeds of the Faculty of Engineering 2019, financed the total development of this research. To the seedbed of research in Infrastructure and Mobility (SIMUN) to which belong the members of this research, to generate the space and time for the development of the activities needed for this research.
