This indicator monitors the development of transport infrastructure networks. Between 1990 and 2023, 1.376 km of new motorways were constructed in Italy (+22.2%). As of 2023, Italy ranks eighth in the world for operational high-speed rail network length, according to the International Union of Railways (UIC).
The indicator assesses the availability and functionality of transport infrastructure across different modes. For road and rail transport, network infrastructures are considered, whereas for air and maritime transport, point infrastructures are taken into account. Transport infrastructure supports national and European markets and enhances social cohesion through accessibility. However, it can also contribute to social fragmentation, land use pressures, noise, and air pollution.
To monitor transport infrastructure networks in order to optimize their use and to revitalize certain modes, such as rail transport and urban fixed-track systems.
Starting with the new White Paper on Transport (28 March 2011), the European Commission outlined key objectives and challenges to be addressed. Among these objectives are: connecting transport networks (rail, airport, maritime, and inland waterways), upgrading infrastructure, and creating a single European airspace with a common aviation regulation framework.
In 2013, the EU adopted Regulation (EU) No 1315/2013 to enhance transport development within the EU, focusing on the Trans-European Transport Network (TEN-T). The regulation introduced two network concepts: the comprehensive network (to be completed by 2050) aiming for EU-wide accessibility and connectivity, and the core network (to be completed by 2030) consisting of the most crucial components of the comprehensive network.
More recently, in April 2021, the Italian Parliament approved the National Recovery and Resilience Plan (NRRP). In particular, Mission 3: Infrastructure for Sustainable Mobility aims to modernize, digitize, and make the national infrastructure system more sustainable by 2026. The goal is to meet the decarbonization targets outlined by the European Union in the framework of the European Green Deal and its related Strategy for Sustainable and Smart Mobility (published on 9 December 2020), and to align with the Sustainable Development Goals of the United Nations’ 2030 Agenda.
Mission 3 is divided into two components:
-
Rail Network Investments: focused on the development of Italy’s high-speed and high-capacity railway system, integration with regional rail services, and ensuring safety across the entire railway network. The primary objective is to enhance rail transport for both passengers and freight by increasing capacity and connectivity, improving service quality along key national and regional corridors, and strengthening cross-border links.
-
Intermodality and Integrated Logistics: includes measures to support the modernization and digitalization of the logistics system.
Additionally, aligned with the strategic framework of Mission 3 and financed through national resources, further investments will be implemented, including:
-
Road Safety 4.0: to enhance the safety and climate/seismic resilience of bridges and viaducts using technological innovation and climate change adaptation approaches.
-
Port system development: to increase the competitiveness, capacity, and productivity of Italian ports, with a focus on reducing pollutant emissions.
-
Strengthening regional rail services: further interventions will be carried out to improve regional railway transport.

A limitation lies in the fact that the length of a transport infrastructure (e.g., highway, railway, etc.) only serves as a proxy indicator of its capacity. In reality, capacity should be measured by the maximum traffic flow the infrastructure can sustain, but this data is currently unavailable.

Indicator assessment
For road networks, railways, metro systems, funiculars, and both urban and interurban tramways, length in kilometers was considered. For ports, the following metrics were used: the number of ports per province, the number of berths, and the number of ports equipped with rail tracks connected to the railway network. Additionally, the total surface area of storage yards and tanks for petroleum products and other liquids (in m²) was included. Finally, container volume and passenger traffic (arrivals and departures) were analyzed for major European ports.
As of 2023, the primary road network in Italy includes motorways (7,561 km), regional and provincial roads (131,095 km), and other roads of national interest (30,193 km), for a total extension of 168,849 km. The motorway network has remained almost unchanged compared to the previous year (Table 1).
Regarding maritime transport infrastructure (as of 30 September 2023), there are 280 ports—many of which are small in size—with a total of 2,486 berths, corresponding to an overall quay length of approximately 510 km. Of these, only 256 are equipped with rail tracks connected to the railway network (Table 3). In the aviation sector, there are 41 airports in Italy open to commercial traffic (certified by ENAC). Among the 20 Italian regions, only Molise and Basilicata lack airports (Table 5).
According to data from the Ministry of Infrastructure and Transport (MIT), the total length of the Italian railway network amounts to 16,762 km, of which 4,575 km are non-electrified (Table 1). Italy ranks 19th globally for total high-speed rail length (including planned/under-construction lines) and 8th for operational HSR lines (Table 6 and Figure 3).
An efficient and sustainable transport system is crucial for connecting regions and countries, as it links markets and people while supporting economic activity, development, and growth. In this context,Italy's current transport infrastructure system exhibits uneven spatial distribution in both road/highway and rail networks, with a clear disparity between Northern and Southern Italy in terms of network length (Table 2).
Regarding passenger rail systems—the country's primary transport infrastructure—the high-speed rail (HSR) network currently terminates at Naples/Salerno. Consequently, populations beyond this segment remain disconnected from the HSR system. This issue also affects Central Italy, where enhanced East-West rail connections are needed to provide inland communities with access to modern rail infrastructure. Further development of the still-limited metro network is also required, while construction is underway on infrastructure components needed to complete the core TEN-T network by 2030.

Until 1980, the data also include the elevators of Genoa and Bergamo. Starting from 1985, the Vicenza interurban tramway was closed, and the “Adda” lines of Milan's ATM are considered as metro lines.

Since 1985, the “Adda” lines of Milan's ATM have been included.
-
Until 1980, the data are estimated and include the funicular of Trieste’s ACT, considered as a tramway. Starting in 2002, the series no longer includes the data from the elevators of Genoa, making the data non-comparable with those from previous years. The Mercogliano-Montevergine (AV) system was closed for operation starting from 12/10/2012 and reopened on 25/06/2016.

During the period 1990-2023, the length of road infrastructure (excluding municipal roads) increased by 13.1%. In 2023, the railway network extended over 16.832 km, comprising 12.205 km of electrified network (+21 km compared to 2022) and 4,627 km of non-electrified network. The total extension of urban and suburban tram networks in 2023 was 431 km, while the metro network length remained relatively modest at approximately 232 km. Terrestrial funicular railways, essential for transportation along steep gradients, are operated in Italy by 19 companies, with a total operational length of 21 km. While primarily serving tourist needs, they often facilitate daily commuting for local residents (Table 1).
Rotterdam, handling approximately 13.4 million TEU in 2024 (13 million in 2023), remained Europe's largest container port by volume, followed by Antwerp (12.4 million TEU in 2024) and Hamburg (7.8 million TEU in 2022) (Table 4 and Figure 1). Gioia Tauro ranked ninth with 3.5 million TEU in 2022 (3.4 million in 2021) (Table 4).
With regard to the passenger segment, in 2024 all the ports considered recorded an overall increase in passenger traffic compared to 2023, with the sole exception of Stockholm (-2%). The three leading ports in terms of passenger volumes are Messina (11.3 million passengers per year), Reggio Calabria (11.2 million passengers), and Naples (approximately 11 million passengers in 2024).
