THE POTENTIAL OF IMPROVED ROUTE GUIDANCE

This paper reports the results of research undertaken since 1977. The purpose was to confirm the size of the benefits which would be available to a perfect system of route guidance and to determine if it is practical to select optimum routes with an accuracy which is sufficient to ensure that a substantial proportion of the identified wastage could indeed be avoided. The results of a survey of driver inter-urban route choice in Gloucestershire are analyzed, and the results are extrapolated to cover the country as a whole and to show the maximum potential benefit of an improved system in terms of saved national resources. A method for selecting optimum routes is described, that uses a model for estimating journey costs directly from maps. The results of a validation experiment are analyzed to show the confidence with which the model can be used as the basis of a system of improved route guidance. (TRRL)
