Preface

Road pricing as an effective means of both managing road traffic demand and raising additional revenue for road construction has been studied extensively by both transportation researchers and economists. Practical implementation has been progressing rapidly and electronic road pricing schemes have been proposed and tested worldwide. It is likely that over the next few years, with increasing public acceptability, there will be greater use of road pricing. The incontestable fact is that there is a great need for the development of efficient road-use pricing models.

Despite a few monographs and journal special issues in the literature that have been devoted to the topic in recent years, most studies have focused on empirical studies, policy experience, environmental issue of road congestion and road pricing. There is still scope for methodological development of advanced road pricing systems, such as dynamic pricing, integrated road and transit pricing, as well as practical toll charging schemes in general road networks. This book is intended to deal with a number of timely topics including: fundamentals of user-equilibrium problems; principle of marginal-cost pricing applied to road pricing; existence of optimal link tolls for system optimum under multi-class, multi-criteria, multiple equilibrium behaviors; social and spatial equity issues in road pricing; optimal design of private toll roads; simultaneous determination of optimal toll levels and locations; trial-and-error implementation of marginal-cost pricing on networks with unknown demand functions; dynamic road pricing.

This book would appear to be the first book devoted exclusively to the mathematical and economic investigation of road-use pricing in general congested networks, which aims at alleviating traffic congestion, improving transport conditions and enhancing social welfare. It constitutes an update of the state of the art of the latest research, mainly by the authors and their colleagues. The book is targeted at students, professionals and scientists who are studying and working in relevant transportation fields.

We are most thankful to a number of individuals for their help during our work in this field. First and foremost we would like to acknowledge the contribution and continuing encouragement of Prof. M.G.H. Bell of Imperial College London (ICL). In fact, the manuscript was finalized during the first author‘s sabbatical leave at ICL in early 2005, and he is particularly grateful to Prof. Bell for his hospitality during a very fruitful and enjoyable stay in ICL. Thanks are also due to Prof. R. Lindsey of the University of Alberta, Prof. E. Verhoef of the Free University of Amsterdam, Prof. W.H.K. Lam of the Hong Kong Polytechnic University and Prof. S.C. Wong of the University of Hong Kong throughout our study of the various road pricing problems and in the preparation of this book. We highly appreciate our research collaboration that produced some of the material included in the book. We also wish to greatly thank three former Ph.D students at the Hong Kong University of Science and Technology, Dr. Qiang Meng (currently at the National University of Singapore), Dr. Xiaoning Zhang (currently at the Tongji University of Shanghai) and Dr. Judith Wang (currently at the University of Auckland) for their contributions to various topics in the book. Thanks also go to Miss Wei Xu and Mr Xiaolei Guo (currently PhD students at the Hong Kong University of Science and Technology) who helped in discussions in earlier drafts of the book. Funding for the research was provided by the Research Grants Council of the Hong Kong Special Administrative Region (HKSAR) and the National Natural Science Foundation, P.R. China.
