A Before and After Analysis of the Impacts of the Inaguration of a New Metro Station in Naples

Abstract

In this paper a before and after analysis of the impacts of the inauguration of a new metro station in Garibaldi square in Naples in Italy will be presented. This station is part of Line 1 and it was inaugurated in January 2014. Moreover, many interventions have been carried out in Garibaldi square, surrounding the station. Therefore a reorganization of the whole transportation system connecting this new strategic node was necessary.Two surveys have been undertaken with the objective of understanding these impacts. Indeed the first one aimed at identifying the present circulation scheme and the one induced by the inauguration of the station. The second one aimed at quantifying the entity of traffic flows in “critical points”, by counting the vehicles during peak periods. From these surveys, it has come out that in the peak morning period (7am-10am) 6,000 vehicles have been counted towards the rail node Garibaldi. This value decreases of almost 15% in the afternoon peak period (12am-3pm) as well as in the evening one (5pm-8pm). A simulation model has been implemented as well in order to estimate future scenarios promoted by the local administration. Indeed the access to the square and to the surrounding areas (where the CBD and the historical centre are placed) changes completely.
