ABSTRACT
The potential role for accessibility measuring techniques as part of transport evaluation in the European Union depends partly upon the evolving policy and administrative approach to transport. However, the demands of the population have increased to a level that cannot be accommodated in physical terms or matched by public funding, and this has been a key factor in creating pressure for transport policy changes. The main focus of transport analysis was therefore on transport demand. All accessibility measures relate to a specific location, origin or destination, and include representation of defined opportunities and a separation element between these opportunities and the location. The opportunity terms, deterrence functions and the sizes of the zones for considering accessibility therefore need to be defined at an appropriate level of detail. The deterrence function can be measured as time, travel cost, distance, or generalised cost/time. It aims to represent real behaviour and perception of travel.
