Paris's role as a centre of international trade and tourism has brought its transportation system many embellishments over the past centuries, and its development is still progressing at a rapid pace today. Only in the past few decades Paris has become the centure of an autoroute system, high-speed train network and, through its two major airports, a hub of international air travel.

Air travel

Paris is served by two principal airports: Orly Airport, which is south of Paris, and the Charles de Gaulle International Airport in nearby Roissy-en-France, one of the busiest in Europe. A third and much smaller airport, at the town of Beauvais, 70 km (45 mi) to the north of the city, is used by charter and low-cost airlines. Le Bourget airport nowadays only hosts business jets, air trade shows and the aerospace museum.

Railway

Paris is a central hub of the national rail network of high-speed (TGV) and normal (Corail) trains. Six major railway stations, Gare du Nord, Gare Montparnasse, Gare de l'Est, Gare de Lyon, Gare d'Austerlitz, and Gare Saint-Lazare connect this train network to the world famous and highly efficient Métro network, with 380 stations connected by 221.6km of rails. Because of the short distance between stations on the Métro network, lines were too slow to be extended further in the suburbs as is the case in most other cities. As such, an additional express network, known as the RER, has been created since the 1960s to connect more distant parts of the conurbation.

Public transport

The public transport networks of the Paris region are coordinated by the Syndicat des transports d'Ile-de-France [29] (STIF), formerly Syndicat des transports parisiens (STP). Members of the syndicate include the RATP, which operates the Parisian and some suburban buses, the Métro, and sections of the RER; the SNCF, which operates the suburban rail lines and the other sections of the RER ; and other private operators managing some suburban bus lines.

The Métro is one of Paris' most important methods of transportation. The system comprises 16 lines, identified by numbers from 1 to 14, with two minor lines, 3bis and 7bis, numbered thus because they used to be branches of their respective original lines and only later became independent. In May 1998, the new line 14 was inaugurated after a 70-year hiatus in inagurating fully new métro lines.

There are two tangential tramway lines in the suburbs: Line T1 runs from Saint-Denis to Noisy-le-Sec, line T2 runs from La Défense to Issy.

Autoroutes

The city is also the hub of France's motorway network, and is surrounded by three orbital freeways : the Périphérique which follows the approximate path of 19th-century fortifications around Paris, the A86 autoroute motorway in the inner suburbs, and finally the Francilienne motorway, also known as the A104 (and N184), in the outer suburbs. Paris has an extensive road network with over 2000 kilometres of major roads and highways. By road Bruxelles can be reached in three hours, Francfort in 6 hours and Barcelone in 12 hours.
