In this paper the findings of a research project, which has been funded by the Economic and Social Research Council, and which has been recently completed at Cranfield, into motorway users adaptive response to uncertainty in motorway travel times are reported. Particular emphasis is placed upon: (1) An examination of how motorway users perceive and quantify uncertainty in their travel times, and how these perceptions vary with the characteristics of the journey, and the time at which it is undertaken; (2) The nature and form of the adaptive behaviour of motorway users in response to levels of uncertainty in their travel times; (3) An examination of the sources of information about possible delays used by motorway users both before and during their journey, and the effect on differing forms of adaptive behaviour; and (4) An examination of the monetary value to which users would be prepared to pay to reduce uncertainty in travel times.
