Abstract: - In this paper, a new approach for decision-making in environmental assessment of urban mobility is proposed. The problem treated is complex with insufficient, fuzzy and uncertain data, with various criteria and information sources. In our application, the traditional approaches, such as life cycle analysis, multi criteria analysis and cost benefit analysis etc, developed for environmental impacts assessment are inappropriate to apprehend the complexity of the evaluation process with its environmental, social, economic and cognitive dimensions. A hybrid approach based on multi criteria analysis and various information sources is proposed. This approach uses fuzzy set theory for modeling criteria and belief theory (Dempster-Shafer Theory (DST)) for evaluations fusion and it is able to handle uncertainty and vagueness for dealing with a complex evaluation problem. A case study related to Park & Ride implementation is used to validate the proposed approach. Key-Words: - Decision support systems, impacts assessment, multi-criteria analysis, fuzzy logic, belief theory.

1 Introduction
In many urban areas, rapidly increasing traffic volumes, lower vehicle operating speeds, type of fuel used and aging of vehicles have resulted in excessive gas emissions, generation of noise pollution and deterioration in living conditions of citizens. In response, the decision makers associated to traffic engineers and urban specialists elaborated various measures for decreasing negative consequences of urban traffic (massive development of the public transport, introduction of fleets with clean vehicles, parking policy in the downtowns, etc). At the same time, any new measure...
