ABSTRACT
Bus services continue to account for a very high proportion of public transport journeys, in many towns, over 90%. In larger cities of over about 2 million people, local railways might account for up to 50% of public transport journeys. The lighter varieties of railway, including trams, are a significant part of the public transport network in much smaller cities of down to around 100 000 population. In some cities, taxis account for a considerable number of urban journeys.
