Abstract: The objective of this work is the optimization of an urban solid waste collection system of a small city from the application of a geographic information system. The optimization in this case is done by the choice of the best possible route. Studies carried out in other municipalities have proved the efficiency of using the TransCAD software for this purpose. Therefore, aiming at a reduction of operational costs, this work presents a case study of the routing of a collection system and destination of all solid urban waste generated in the city of Tiros (MG). Field surveys have confirmed that the route of the collection system is performed empirically, making a total daily route of 40.8 km, within 8.1 hours. The TransCAD (SIG) computational program vehicle routing with time windows tool was used. From the routing, minimizing the distances, the total route was 34.9 km, which represents a saving of 13.3% in mileage. With routing minimizing the time of travel, if you can reduce it in 23 minutes it will represent a saving of 4.8%. Therefore, routing is a great tool to save expenses with waste collection and disposal fleets, and consequently, public spending and routing optimizing distance is the most effective.
