Impacts Analysis towards a Sustainable Urban Public Transport System.

Abstract:

Nowadays, both big and small cities look to optimize their urban public transport systems through models that allow reduction of transfer time and environmental impacts, to create sustainable cities. Thus, cities of Latin American countries are adapting their public transport systems to energetic sustainability conditions. This study analyzes the impacts of transport models and chooses the best alternative, considering four cities with a high urban mobility index and optimal conditions of sustainable development. A review of scientific literature is conducted and priority criteria, such as traffic, environmental impact, social impact, and economic impact are established and evaluated via the Analytical Hierarchy Process (AHP) decision making method. As a result, the AHP model defines the city of Curitiba as the best sustainable transport alternative, with 31, 8% against 27, 6% of Singapore, 17, 8% of Santiago de Chile and Montreal with 22, 9%. The proposal uses a four-step transport model: trip generation, trip distribution, mode choice and route assignment.
