Hong Kong, with a land area of only 1,105 square kilometres has a population of more than seven million.

Every day, over 12.6 million passenger journeys are made on a public transport system which includes railways, trams, buses, minibuses, taxis and ferries.

There are about 347 licensed vehicles for every kilometre of road, and the topography makes it increasingly difficult to provide additional road capacity in the heavily built-up areas.
