FOREWORD Transit administrators, engineers, and researchers often face problems for which in- By Staff formation already exists, either in documented form or as undocumented experience and Transportation practice. This information may be fragmented, scattered, and unevaluated. As a conse- Research Board quence, full knowledge of what has been learned about a problem may not be brought to bear on its solution. Costly research findings may go unused, valuable experience may be overlooked, and due consideration may not be given to recommended practices for solv- ing or alleviating the problem. There is information on nearly every subject of concern to the transit industry. Much of it derives from research or from the work of practitioners faced with problems in their day-to-day work. To provide a systematic means for assembling and evaluating such use- ful information and to make it available to the entire transit community, the Transit Co- operative Research Program Oversight and Project Selection (TOPS) Committee author- ized the Transportation Research Board to undertake a continuing study. This study, TCRP Project J-7, "Synthesis of Information Related to Transit Problems," searches out and synthesizes useful knowledge from all available sources and prepares concise, documented reports on specific topics. Reports from this endeavor constitute a TCRP re- port series, Synthesis of Transit Practice. This synthesis series reports on current knowledge and practice, in a compact format, without the detailed directions usually found in handbooks or design manuals. Each re- port in the series provides a compendium of the best knowledge available on those meas- ures found to be the most successful in resolving specific problems. PREFACE This synthesis documents the current state of the practice for web-based surveys. The intent of the report is to provide a resource for successful practice, discuss the technologies necessary to conduct web-based surveys, and present several case studies and profiles of transit agency use of web-based surveys. The topic will be of interest to transit planners and managers and those who work with them as they attempt to develop and refine web-based surveys for their own transit agencies. Particular emphasis is placed on understanding the strengths and limitations of all survey methods. Information presented in this synthesis was obtained from a literature review, as well as from survey responses from 36 transit professionals. Follow-up telephone calls were made to gather further information. Longer telephone interviews were conducted to develop three detailed case studies: NJ TRANSIT, Southern California Regional Rail Authority (Metrolink), and Tri-County Metropolitan Transportation District of Oregon (TriMet). Greg M. Spitz, Frances L. Niles, and Thomas J. Adler, Resource Systems Group, Inc., White River Junction, Vermont, collected and synthesized the information and wrote the paper, under the guidance of a panel of experts in the subject area. The members of the Topic Panel are acknowledged on the preceding page. This synthesis is an immediately use- ful document that records the practices that were acceptable within the limitations of the knowledge available at the time of its preparation. As progress in research and practice con- tinues, new knowledge will be added to that now at hand.
