Objective

To analyze associations between road infrastructure and Work-Related traffic accidents, in Medellin 2010-2014 in freight and passenger drivers.

Methods

A retrospective cross-sectional study to establish a possible association between road infrastructure and work-related traffic accidents with injuries for the driver in Medellín Colombia, using the Police traffic accident database, from January 2010 to July 2014.

Results

There were 102 602 records of traffic accidents. The multivariate analysis was conducted with 8516 records with complete information from March to July 2014. The factors associated with injury were: collision with another vehicle (PR 1,31 95CI 1,09-1,57); two-lane roads (PR: 1,21, 95% CI 1,14-1,33) and three-lane roads (PR: 1,39, 95CI 1,091,76); being a driver between 18 and 24 years old (PR 1.13 95 CI 1,02-1,26); and driving under the influence of alcohol (PR: 2,81 95% CI 2,42-3,26). In addition, through analysis of geographic information, critical points of work-related crashes were identified.

Conclusion

A growing trend of work-related traffic accidents was identified in Medellín. Special attention must be addressed to passenger and cargo transport due to its significant contribution to traffic accidents in the city. The monitoring of infrastructure and areas with the highest inci-dence can be useful in the design of prevention programs in transport companies.
