The Metro operates on of route, serving 77 stations. On 12 May 2018, the western terminus of Line C was moved to San Giovanni (interchange station for line A). On 16 December 2025, the western terminus of Line C was moved to Colosseo (interchange station for line B). It has a daily ridership of approximately 820 thousand passengers, and an annual traffic of approximately 320 million passengers. Line B was the first metro line inaugurated in the system, and the first official metro in Italy, but the names 'A' and 'B' were only added when the second line opened 25 years after the first. Inaugurated in post-war Italy in 1955 during the reconstruction and on the verge of the Italian economic miracle, it was designed and built for the 1942 universal exhibition (Esposizione Universale Roma, which is now the current business center of Rome) desired by the fascist regime, which never took place due to the outbreak of the World War II.

All Rome metro lines are heavy rapid transit lines, with 6-car trains, approximately 105 m long. Line A of the Rome metro uses exclusively the CAF MA 300 series, line B essentially uses the CAF MB400 series together with other CAF MA300 series trains and the historic MB 100 Ansaldobreda. Line C is the longest driverless metro in Italy and one of the largest in Europe, using Hitachi Rail Italy's driverless technology.

Classification of bus routes

Bus routes in Rome are identified by a symbol and a small letter:

U (Urban bus routes) - regular bus routes around Rome, calling at all stops and operating mostly between 5 am and 12 am. These routes include also one summer seasonal route (062). They are identified by a U letter and a blue background on their number reported on bus stops. X (Express bus routes) - they are 12 bus routes (20, 30, 40, 50, 51, 60, 80, 90, 120F, 150F, 180F and 190F). These routes connect the centre of Rome with some far away suburbs and call at lesser stops than Urban routes and tend to have a higher frequency. On bus stops, they can be identified with a green colour and an X letter. E (Exact bus routes) - they are a bunch of bus routes with a reduced timetable and operating mainly through peripheral areas of Rome. The name exact is due to their timetables being strictly adhered to. These routes also include those serving local cemeteries. On bus stops, they are identified with a brown colour and an E letter. N (Night bus routes) - indicates Rome's night bus network, it is made up of 31 lines and serves a large part of the city, the system also includes 4 night lines (nMA, nMB, nMC and nME) which respectively cover the routes taken by the metro and the Rome-Lido railway (Metromare) when these are closed. They are active from 23:30 to 5:30 am. At the bus stops the night lines are identified by a midnight blue colour, the letter "N" and an owl next to the line number.

Route numberings and service areas

Most bus routes in Rome have three digits. The route numberings, in such cases, depends from the division in Rome in 10 zones (0 to 9). For instance, in case of route 916 it starts from zone 9 (Trionfale-Cornelia stop) and terminates at Rome Termini station on zone 1 (city centre).

The only exceptions to this system are routes 446 (connecting zones 9 and 2) and route 201 (unchanged since 1934). Both of which had been established on a previous numbering system not adjourned.

Other features which can be seen are:

Letters:

C××× (the letter C stands for cemetery, and as such it identifies those routes connecting residential areas with local cemeteries) F (any bus route with the letter F after a numbering operates only on Sundays and public holidays) H (route H is the only route in the entire network which number consists only in a letter) N (any bus route with the letter N operates during nights only)

In other cases, there are routes whose first digit is 0. It stands for those peripheral routes operating outside the Grande Raccordo Anulare at all times.

Interurban bus transport

Various coach operators can be found in Rome, such as Flixbus, Marino, Busitalia Fast-SIMET and Baltour, operating various connections nationwide and internationally. These mainly depart from the bus stations in Anagnina and Tiburtina (TIBUS), where hundreds of national and international bus lines converge, in terms of passenger volume, around 8 million per year, it is the largest bus station in Italy.

Located in the center of the Italian Peninsula, Rome is the main railway hub in central Italy, connected by high-speed lines with Florence, Bologna, Milan, Turin, Venice, Naples and Salerno. The other main traffic routes follow - at least in the initial part of the route - the route of the Roman roads: the Tyrrhenian line (Rome-Genoa, along the Via Aurelia); the line northwards initially along the Tiber valley (Rome-Florence-Bologna); the lines towards the Adriatic (Rome-Pescara, along the Via Tiburtina, and Rome-Ancona, along the Via Flaminia); the lines towards the south (Rome-Formia-Naples, along the Via Appia, and Rome-Cassino-Naples, along the Via Casilina).

Roads

Rome is served by an extensive motorway network. The most important motorway serving the city is the A90, also known as Grande Raccordo Anulare or GRA (Great Ringroad) which run in a circle around the city. The GRA is connected to the Roman branch of the A1 Milan - Naples and other three motorways which arrive further inside the city: the A12 Genoa - Roma, the A24 Teramo - Roma and the A91 Roma - Fiumicino Aeroporto. All maintened by Anas, the Italian road infrastructure manager.

Traffic congestion in Rome is notorious.50 Years in a Cab: A Long, Winding Trip for One Driver, and His City By Elisabetta Povoledo 13 April 2016 New York Times This issue is caused mainly by the undersized public transport network and the extremely high cars per capita ratio in the city. It is one of the highest ratios in the country. The Metropolitan City of Rome is the second province in Italy by automobiles per capita (0,687) and 5th by vehicles per capita (0,87).

Motor Traffic Limited Zone (ZTL)

Chronic congestion caused by cars led to the partial banning of motor traffic from the central part of the city during workdays, from 6 am to 6 pm. This area is called Zona a Traffico Limitato (ZTL), motor traffic limited zone.

Heavy traffic due to night-life crowds during weekends led in recent years to the creation of other ZTLs in the Trastevere, San Lorenzo, Testaccio and Monti districts during the night.
