Challenge

Throughout its more than 25 years, the Transit Capacity and Quality of Service Manual (TCQSM) has compiled the state of the practice based on peer-reviewed research published by the Transportation Research Board. The TCQSM is a key reference for transit agencies across the country. The 3rd Edition was published over 10 years ago, so the manual needed to be updated with modern best practices.

Solution

Alongside our partners at WSP USA, Texas A&M Transportation Institute, Foursquare ITP, and Queensland University of Technology, our team led the development of a 4th Edition of the TCQSM that includes research that has occurred since 2013. The update addresses the numerous transit technologies and practices that have emerged or advanced since the last edition, including microtransit and low-speed automated vehicles, and it expands its coverage of widely adopted technologies such as bus and ferry electrification. This edition also addresses key concepts related to modes and services, operations, quality of service measures and applications, bus transit, demand-responsive transit, rail transit, ferry transit, and transit stops and stations.
