The objective of the symposium was to provide a forum for the exchange of information about state-of-the-art research and technology applications to improve snow removal and ice control operations in transportation systems. Sixty-one papers were presented in the areas of policy and management, infrastructure and snow control, materials and applications, equipment, travel surface, environment and health, road weather information systems and forecasting, and safety and visibility. Papers were authored by maintenance engineers and researchers from Austria, the Czech Republic, Denmark, Finland, Germany, Japan, New Zealand, the Netherlands, Norway, Russia, Sweden, the United Kingdom, and the United States. Twenty-one of these papers are included in this publication.

This major reference work the first of its kind provides a comprehensive and authoritative introduction to the large and growing literature on contingent valuation. It includes entries on over 7,500 contingent valuation papers and studies from over 130 countries covering both the published and grey literatures. This book provides an interpretive historical account of the development of contingent valuation, the most commonly used approach to placing a value on goods not normally sold in the marketplace. The major fields catalogued here include culture, the environment, and health application. This bibliography is an ideal starting point for researchers wanting to find other studies that have valued goods or used techniques similar to those they are interested in. For those wanting to conduct meta analyses, the book will serve as an invaluable guide to source material. For those wanting to conduct meta analyses, the book will serve as an invaluable guide to source material. In addition to the print edition we offer access, for purchasers of the book, to a website providing the contents of as a searchable Word document and in a variety of standard bibliographic database forms. Contingent Valuation is an indispensable reference source for researchers, scholars and policymakers concerned with survey approaches to the problem of environmental valuation.

This report contains 56 conference papers pertaining to snow removal and ice control research including Canadian research and equipment. Several of the papers are concerned with deicing salts--their effectiveness, their impact on the environment, and possible alternatives to them. Alternative methods of deicing discussed herein include: heating of bridge decks, increasing coefficient of friction between tires and pavement surfaces, use of high intensity lights, and advent of less corrosive chemicals. There are also several papers that address the problem of snow and ice accretion on power wires, guideway systems, sign boards, and etc. There is considerable attention given to development of computer programs and models for predicting scope of snow and ice control operations and for evaluating their effectiveness. Also, several papers discuss new developments in snow removal equipment and the cost of operation and maintenance.
