The routines of support to decision-making in the environment of Geographical Information Systems (GIS) have provided an increase in both flexibility and complexity of analyses by means of this tool. This work presents the application of tools of support to the decision-making in Geographical Information System in order to assist in the evaluation of design alternatives for the urban ring road of the city of Viçosa, Minas Gerais State, Brazil. The selection of alternatives was possible through the application of integration GIS - Multicriterion analysis, employed in analyses related to available and viable areas according to geotechnical, relief, socio-economical, operational and environmental aspects. The spatial data analysis and processing was performed with the utilization of supporting modules to the decision of software GIS Idrisi 32. The result of the accomplished simulations comprises a very important subsidy to the decision-making on the best design alternatives, making possible a technical selection according to the previously mentioned aspects. The model proposed in this work can be easily incorporated to studies and anteprojects of road designs or to other infrastructure works without necessarily incurring high costs.
