The higher densities and more intense land uses associated with larger cities gives more incentive for pedestrian and other environmental improvements. In Britain, smaller sums of money have been paid to transport consultants to prepare reports to explain the problems and the potential of light rapid transit to help solve them. Loss of shopping, commercial activity and jobs from the city centre has been at least partly, and for some sectors largely, a transfer rather than an absolute loss. Improved public transport would probably help to transfer some of it back again and to transfer substitute activities from the inner city to the centre. The city centre is the location of some facilities which could thrive nowhere else. Cities need centres to maintain and develop the unique facilities that can only be there, and in developing these faculties other non-unique activities will be attracted as well.
