There is mounting concern amongst policy makers regarding the economic, social and environmental impact of traffic growth, particularly in urban areas. As a result, many cities throughout the world are currently considering the introduction of road pricing or tolling schemes, either to directly limit travel demand or to raise revenue to finance appropriate capacity expansion. However, the success of such schemes depends on how travellers modify their behaviour in response to the new charges and, to date, practical experience of such responses is limited. The purpose of this paper is to present some initial results from an ongoing study which is monitoring the impact on travel behaviour of the introduction of an electronic toll ring in the Norwegian city of Trondheim in 1991. The monitoring study is based on travel diary surveys carried out one year before and one year after the introduction of the toll ring. The surveys were of a panel design, involving re-interviewing the same individuals, and as such enable the assessment of change at both an aggregate and a disaggregate level. After a short presentation of the background and context of the Trondheim scheme, the paper concentrates on describing the changes in travel behaviour which have taken place in commuting, shopping and other journey categories. The paper particularly concentrates on those changes in travel behaviour (e.g. frequency, mode, trip length) which are of most significance to environmental impact.
