Abstract

The new proposed law aimed at reorganizing the Italian administrative territorial institutions, called Delrio, has raised a big debate regarding the correct identification of the metropolitan cities and definition of their boundaries. This law states that basically the metropolitan city boundaries should correspond to the provincial ones. The present paper is aimed at contributing to this debate from a different point of view. Mobility is changing across the whole Europe, however different trends could be identified in different areas. Understanding this changes and the characteristics of the future mobility could support the stakeholders in the difficult process of identification of the new metropolitan cities boundaries.

Highlights

The first Italian law regarding the reorganization of administrative territorial institutions (L.142/1990) defined a metropolitan city as a core city with the surrounding towns strongly connected in terms of economic activities, essential public services, cultural relations and territorial features
The present paper analyses the main changes in passenger mobility in the province of Turin area, to understand if the metropolitan city could coincide with its province
A similar trend is evident when analysing the change in the number of foreign residents (Fig. 3): this driver presents a different behaviour in the two identified zones, with a more significant increase of foreign population in the surrounding of Turin than in the mountain municipalities. These trends confirm the changes in mobility patterns that have been observed in the study area in the same time period (2000-2010, [16,17]): − with respect to the total passenger demand of the Province area, the share of demand generated and attracted by the Turin metropolitan area has increased from 68% to 71% while trips in the rest of the province have decreased; − inside the metropolitan area, Turin still represents the most important attracting and generating node, but the quota of passenger flows from or to Turin has decreased from 81% to 77% while trips having both origin and destination in the Turin surroundings have increased from 19% to 23%. This figures show that the municipalities around Turin are raising their importance as attracting and generating nodes and confirm the occurring urban sprawl phenomenon which is contributing to the progressive extension of the metropolitan area; − considering trips generated or attracted by the rest of the province, inner trips have slightly decreased, while passenger flows from and towards the metropolitan area have shown a slight increase from 18.9% to 20.3%; in this case it’s interesting to notice that the number of trips coming or going to the city of Turin diminished in favour of flows towards the suburban areas

Summary

Introduction

The first Italian law regarding the reorganization of administrative territorial institutions (L.142/1990) defined a metropolitan city as a core city with the surrounding towns strongly connected in terms of economic activities, essential public services, cultural relations and territorial features. The new “Delrio law”, states that the metropolitan city boundaries should correspond to the provincial ones. This controversial choice has led to a discussion among various stakeholders, who highlighted the risks of applying the same institutional model to wide areas with big territorial, demographic, social, economic and mobility differences. The present paper analyses the main changes in passenger mobility in the province of Turin area, to understand if the metropolitan city could coincide with its province. In the first paragraph the main drivers affecting passenger mobility are identified and analysed to understand the big changes that they are bringing about in mobility. The second paragraph focuses this analysis on the Turin case study and investigates the main mobility drivers changes in different areas of the province. Some conclusions regarding the correct identification of Turin metropolitan city boundaries are drawn
