A low-cost approach to more sustainable transport is to make more efficient use of existing transport facilities and minimise the number of vehicle trips to traffic-generating sites (such as schools, companies, hospitals and shopping centres) through the use of organisational, information and awareness tools. This is mobility management. It includes strategies such as better information on sustainable transport solutions, improving collective transport for specific user groups, the co-ordination of car-pooling and public awareness campaigns. The emphasis is on encouraging the private sector to share responsibility in promoting sustainable mobility, and on a voluntary change in individual behaviour, through the use of mobility management centres/ co-ordinators at a regional, local or site level.
