Abstract:
This study aims at contributing to increase road safety by expanding knowledge on how to identify safe urban routes for Hazardous Materials that are commercially doable. A bi-level linear model was implemented in GAMS modelling software considering fuel distribution data and the road network for the city of Lisbon. Its first level consists in road risk minimization whereas the second level aims at maintaining the economic viability of the itineraries. This work expands the research of Rodrigues et al. (2015) by increasing: (1) the comprehensiveness of the road data, and (2) the complexity of the analysis by including, besides resident population, hospital and school users potentially affected by an accident, and by comparing different itineraries and the computational time needed to solve the model. The work analyses much more comprehensive data than those found in previous studies in the literature and was successful in identifying optimal solutions, most of which in short computati
onal time. This suggests that this methodology can be used by the industry to identify routes for fuel distribution in urban environments. In the future, the routes generated by the model will be compared with routes currently used in fuel distribution.
