Buses are the largest road carrier, responsible for roughly one-third of the daily public-transport trips excluding those by taxi, followed by the combined minibus and maxicab (a regulated form of minibus) service. Commuter rail service also accounts for about one-third of overall ridership. The precipitous Victoria Peak area is served by one of the oldest transport companies, which operates a cable-car system between the peak and the Central District.

International traffic is served by Hong Kong’s international airport and its magnificent harbour, and there are good overland linkages with Guangdong province.

The Hong Kong International Airport was located at Kai Tak, on the eastern fringe of Kowloon, until 1998, when it was relocated to a new, larger facility on Chek Lap Kok Island. Designed by British architect Sir Norman Foster, the airport’s passenger terminal is among the world’s largest enclosed spaces, covering some 133 acres (54 hectares). The port of Hong Kong, based at one of the world’s finest natural harbours, is renowned for its efficiency and capacity. The capacity of its container terminals at Kwai Chung ranks Hong Kong among the world’s largest container ports. Speedy ferry service between Hong Kong and Macau and parts of Guangdong is provided by various craft, including hydrofoils and hovercraft.

Passenger and freight rail services are provided by the Kowloon-Canton Railway (in operation since 1910). Electrification and double-tracking of the railway and the growth along its lines of the new towns of Sha Tin, Tai Po, Fanling, and others caused a considerable increase in passenger traffic. The railway’s commuter services expanded considerably with its merger in 2007 with MTR Corporation, which had been established in 1975 to develop and operate Hong Kong’s mass-transit system.

Hong Kong’s rail system is connected by a line running to nearby Shenzhen and, to the northwest, Guangzhou (Canton) in Guangdong province; the line carries millions of tons of freight annually, as well as passenger traffic betweenHong Kong and Guangdong.

Hong Kong has one of the world’s most advanced and technologically sophisticated telecommunications systems, and it is one of the principal centres of the global telecommunications network. Hong Kong is a leader in integrating multiple-platform communication modes (e.g., land-line and mobile telephony) and implementing the most cutting-edge technology. Land-line telephones are nearly ubiquitous among Hong Kong households, and mobile-phone subscriptions exceed considerably the total number of inhabitants. Internet use is widespread, a large proportion of it using broadband. Britannica
