RESUMO

This dissertation deals with a methodological process to be applied during the planning stage of urban expressways. A multicriterial analysis is proposed to select the most adequate alignment of the future highway, considering not only geometrical engineering factors, usually taken in account in highway design, but including other important questions of a modern society, such as the environmental ones. Initially, a bibliographical review was conducted involving international and brazilian experiences, where the study of alignment alternatives took in account several factors, including the environmental ones, in order to define a set of criteria and indicators to be used in the evaluation of different alternatives. Then, with the support of highway and environment specialists, a new set was proposed. Finally, the number of criteria and indicators was reviewed and reduced to conform to available data and applied in a case study. The model proposed to analyse and evaluate alignment alternatives was developed in successive stages – from bibliographical review to data collection – establishing a hierarchical set of criteria and indicators. This model was applied in a case study related to the study of alignment alternatives of the São Paulo Ring Road, through interviews with different agents and the application of the Analytic Hierarchy Process – AHP. Results obtained indicated that the proposed model is suitable to be applied in the planning stage of an urban expressway, leading to strategic environmental impact assessment, and pointing environmental factors as the most critical and important ones in an alignment alternatives study. It is understood that the selected alternatives under this process are the ones that present less critical environmental impacts, according to judgements expressed by different agents from several society sectors involved with this matter.
