There are several forms of public transport in the UK. Statistics suggest that forms of public transport are becoming increasingly popular, due to relatively cheap cost when compared to private transport. In addition to this, public transport is often quicker and more reliable, especially when travelling in busy cities, such as London. One reason why public transport is increasingly popular in London is the ease in which people can travel around the city centre. Services such as the Underground provide the opportunity to beat traffic congestion and negate the need for often costly parking. In addition, the regularity of such services is popular. However, public transport is often less popular in less densely populated areas. A possible reason for this is that services tend to be less regular, making public transport a less practical option.
