Abstract
Publication of the second edition of the "Transit Capacity and Quality of Service Manual" (TCQSM), Transit Cooperative Research Program (TCRP) Report 100, concludes more than a decade of effort. The comprehensive document assembles a range of information and procedures to aid transit planners, operators, and researchers. The 572-page book with CD-ROM is a companion to the Transportation Research Board's renowned reference, the "Highway Capacity Manual." In this article, a key player in the original development of the manual reviews some of the major concepts and their applications, as well as the new and expanded material.
