Colombia has joined global efforts to achieve net-zero emissions targets. To this end, it has implemented a regulatory framework that provides incentives for electric vehicles. Accelerated growth in the use of electric vehicles in Colombian cities is expected in the short term; in that sense, governmental planning and, therefore, the study of the behavior of this new system is necessary. In this work, a spatial model was developed for an intermediate city in Colombia built in SUMO and a cost model developed in Python to evaluate the current state of individual public mobility services with combustion vehicles. The case study will allow the future to create a planning methodology to select sustainable projects, including electric cars and renewable energies in intermediate cities.
