TCRP Synthesis 140: Comprehensive Bus Network Redesigns provides an overview of the current state of practice regarding comprehensive bus network redesign. The study examines practices among agencies of different sizes, geographic locations, and modes.

The report captures the many components that are needed to successfully plan and implement a redesign and carefully considers the goals and objectives that agencies set forth when they began that process, helping them determine whether a redesign even made sense for the agency at that point in time.

Comprehensive bus network redesigns, in which transit agencies fundamentally alter the structure and organization of their bus networks, are not completely novel in transit. However, redesigns have become seemingly more common in recent years. The motivations for embarking on network redesigns vary across transit agencies, but, given the prevalence of redesigns in recent history and with more redesigns likely to come, the transit industry will benefit from improved documentation of network redesign rationales, outcomes, best practices, and challenges.
