A new commentary from Reason Foundation examines how Denver's Regional Transportation District (RTD), which serves more than 3 million residents across eight counties, compares to metro Atlanta's fragmented approach where multiple agencies like MARTA, Ride Gwinnett, CobbLinc, and others each operate separate transit services. The analysis reveals that while Denver's single-agency model enables fast, systemwide decisions on fares, routes, and budgets, it also concentrates accountability in ways that exposed serious problems after the pandemic, ultimately forcing state lawmakers to restructure the agency's governing board.
Denver's RTD operates through a 15-member elected board that controls bus, light rail, commuter rail, and paratransit across the region, funded primarily by one sales tax collected across its eight-county district. Metro Atlanta has no comparable structure. MARTA's sales tax is collected only in its member jurisdictions, while Cobb County pays for CobbLinc and Gwinnett funds Ride Gwinnett from its own revenue. In 2024, RTD simplified the system's fares in a single board action, cutting prices and reducing the network to two zones—a change that would require multiple agencies to coordinate and agree in Atlanta. Following the pandemic, Denver's ridership remained about 39% below pre-pandemic levels and continued to decline in early 2025, while fare revenue fell to only about one-third of its 2019 level after adjusting for inflation. Rail maintenance pushed light rail on-time performance down to 59.9% in August 2024 before it improved.
The report finds that the strongest argument for a single regional agency is "its ability to plan transit as one network rather than as a collection of separate services." Through initiatives like Reimagine RTD and its System Optimization Plan, Denver can compare bus service, rail investments, station improvements, and paratransit to determine which produces the greatest benefit when travel patterns change. According to the analysis, regionwide planning is more difficult in metro Atlanta "because authority is divided among several governing bodies," meaning a redesign comparable to Denver's would require multiple agencies to agree on priorities, funding, and implementation. A 2024 state audit identified weaknesses in RTD's asset management, budgeting, and implementation of earlier reforms, with operational, financial, and governance concerns raising broader questions about whether the structure provided sufficient accountability.
Denver's struggles show that consolidating transit power doesn't eliminate problems—it just changes who's responsible when things go wrong. Because RTD makes the region's major transit decisions, all the post-pandemic operational failures, financial shortfalls, and safety concerns traced back to one governing board, making it easier for lawmakers and the public to identify the source of accountability but also exposing the board to intense scrutiny. Those concerns led Colorado lawmakers to create the RTD Accountability Committee through Senate Bill 25-161 and later approve Senate Bill 26-150, which restructures RTD's governing board beginning in 2029, shrinking it from 15 elected members to nine—five elected and four appointed by the governor. Metro Atlanta faced the opposite problem: since no single agency oversaw regional transit planning and investment, multiple jurisdictions had to work together to set priorities before any regional projects could begin. Rather than merging its transit operators, Georgia established the Atlanta-region Transit Link Authority in 2018 to coordinate regional planning, then merged it with the Georgia Regional Transportation Authority in 2026 into the Georgia Transportation Efficiency Authority managed by a new 13-member board.
The report concludes that neither state abandoned its underlying governance model but instead sought to address limitations within existing systems. It recommends that metropolitan regions "plan as one" by scoring competing projects through a common regional process, pointing to Virginia's SMART SCALE program as a model where transit investments can be evaluated using common performance measures without consolidating agencies. The analysis also urges states to "evaluate governance before problems force reform," noting that both Colorado and Georgia acted only after weaknesses became difficult to ignore and suggesting periodic independent reviews tied to major planning cycles. The bottom line: whether transit runs through one agency or many, what matters most is having the right checks in place before breakdowns force lawmakers to rebuild the system under pressure.
