The first section of this chapter outlines the general situation concerning the use of road tolls in Norway. Detailed results are then given of a diversion study which involved the E6 route from Trondheim eastwards to the airport. Surveys were conducted on both the new tolled motorway and the old lower standard route in November 1989 and 1990. Variations in toll road usage are discussed. New evidence concerning the relationships between stated and measured time savings are introduced. The last 2 sections address the question of modelling route choice under the influence of tolls. Simple models for forecasting are described and applied, and more fully specified models based on data from two consecutive years are developed. These are applied to study variations in values of time.
