Abstract

A sustainable mobility in the urban areas needs integration between transport and environmental planning. Possible strategies of improvement of transport systems are substantially amenable to two general principles. The first strategy is the development of an equable transport system, in which every transport mode is used in its technical-economic validity and environmental compatibility field. The second strategy consists of combining demand management policies and supply improvements, like park pricing, road and area pricing, car-sharing or car-pooling, etc. In this perspective, in the study the consumers’ answers to the adoption of some of these strategies are analyzed; to such purposes, methodologies of mobility surveys are been used, both traditional type (Revealed Preferences techniques) and innovative type (Stated Preferences techniques). The research concerns the mobility characteristics in the University of Calabria, situated in the urban area of Cosenza, a town in Southern Italy; the campus is attended by about 30,000 people. SP techniques have been applied, particularly in order to verify the consumers’ satisfaction to the improvement of services of the transport system. Conjoint RP/SP mode choice models, using RP and SP data on the same sample, have been calibrated; further, an elasticity analysis has been made. These models can be used for demand forecast. Keywords: urban mobility government policies, Revealed Preferences, Stated Preferences, elasticity analysis.
