Economic growth and globalisation create traffic growth, leading to congestion, which again increases travel times and costs. Traffic growth also increases CO2 emissions, air pollution, accidents, and noise. So, clearly there is a need to manage traffic, taking into account that there is a need for transportation; hence it cannot be restricted without costs.

Road pricing, where motorists pay for driving on specific roads, is an instrument that may efficiently reduce the negative impacts. But despite technological development and the efforts of the EU, it is still not widely used. Apparently, more research-based knowledge about the positive and negative consequences of road pricing is required.

This volume is a collection of research papers on the use of road pricing. The focus is on passenger transport, and the papers cover a wide range of approaches, including theoretical modelling and empirical studies of road pricing experience from different cities.

This book is based upon contributions to a Scandinavian conference on Transport, Agriculture and the Environment in a Regional and National Development Per spective: Quantitative and Modelling Approaches, organised by AKF, the Institute of Local Government Studies, Denmark, which was held on the Danish island of Bornholm in December 1993. The chapters represent leading edge research in Scandinavia at the end of 1993 into modelling relationships between the economy and the environment, embracing both regional and sectoral perspectives. The publication of this volume will hopefully contribute to dissemination of knowledge about the very active Scandinavian research tradition in this field, a research tradition which is related to a long-standing engagement of Scandinavian countries with environmental issues. The contributors come from Denmark, Norway and Sweden and the collection is prefaced by two chapters from well-known Dutch researchers, traditionally re garded by Scandinavians as close neighbours to the Scandinavian modelling tradition. The support of S0M (Society, Economy and Environment), an open research centre financed by the Danish Environmental Research Programme, and of AKF in the organisation of the original conference and the preparation of this book is gratefully acknowledged. It was with great sadness that the editors learned of the death of one of the contri butors, Poul Erik Stryg, during the preparation of the book."
