Abstract
This report analyzes the optimal organization of public transit service in large U.S. metropolitan areas—like Los Angeles and the San Francisco Bay Area where multiple operators serve overlapping markets. It synthesizes over 50 international and U.S. studies of: (1) regional transit governance and coordination, (2) economies of scale and scope in transit operations, and (3) service contracting. The report finds that regions gain the most from coordinating front-end, customer-facing functions such as marketing, fares, information, and service planning through a regional association or authority, while leaving back-end service-production and delivery decentralized among sub-regional operators. This approach enhances riders’ travel experience, increases ridership, and improves cost efficiency. Conversely, large-scale transit agency mergers rarely save money and often introduce diseconomies of scale due to increased organizational complexity and higher labor costs. For some large agencies, contracting certain services coupled with strong oversight and performance-based incentives can lower costs. The report concludes that combining regional coordination of front-end, customer-facing functions with decentralized back-end service production offers an optimal blend of service coordination and cost-effectiveness.
