Hong Kong, with a land area of only 1,099 square kilometres of which about 17 per cent is built-up, has a population of more than six million. Every day, over 11 million passenger journeys are made on a public transport system which includes two high capacity railways, trams, buses, minibuses, taxis and ferries.
There are about 275 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.
