Abstract

This paper focuses on a real case study concerning a reorganization of the railway system of the Salerno province (in the Campania region). In order to analyze the feasibility of a new railway connection a two-step procedure is proposed. First, a sub-set of feasible scenarios is identified through a stated preferences analysis, then the most effective scenario has been sorted out by modelling the whole transportation system. The transportation system has been simulated by dividing the study area into three sub-areas and for each sub-area a different mathematical model has been used. For each scenario, the demand variation has been assessed, and the impacts on the supply system performances have been evaluated. Keywords: travel demand analysis. 1 Introduction In recent years the considerable increase of car use has been contribute to involving noise and air pollution, energy consumption, road safety and, not least of all, user travel times. Although new strategies for the travel demand control, in many situations the only effective solutions are infrastructural interventions on the supply system. The construction of public facilities generally entails considerable economic, social and environmental costs. On designing new infrastructures it is imperative therefore to test the effectiveness and the efficacy of the new projects devised by simulating possible scenarios. This paper focuses on a real case study concerning a reorganization (three new stations, higher service frequencies and faster trains) of the railway system of the Salerno province (in the Campania Region, see Figure 1). In order to analyze the feasibility of a new railway connection, the Campania region has co-
