Friday Roundtable: Intercity Bus Routes

Key Takeaways

• 72 operators mapped via GTFS, offering a nation‑wide intercity bus view
• Northeast, Midwest, and central Florida show the densest bus corridors
• Washington’s WSDOT subsidies increased daily trips on four key routes
• New Wheat Line will launch spring 2026, linking Spokane to Pasco
• Study’s criteria exclude commuter, seasonal and van‑based services

Pulse Analysis

The University of Illinois Urbana‑Champaign’s Urban Traffic & Economics Lab has compiled the most comprehensive GTFS‑based dataset of U.S. intercity bus routes to date. By aggregating schedules from 72 operators, the study creates an interactive map that visualizes a network far larger than most travelers assume. Its rigorous definition—requiring distinct metropolitan connections, independent ticketing, over‑the‑road buses, and year‑round service—filters out commuter shuttles and seasonal charters, delivering a clear picture of true intercity mobility.

Regional analysis shows that the Northeast, Midwest and central Florida host the most densely packed corridors, mirroring population centers and economic hubs. Compared with the fragmented passenger‑rail landscape, these bus routes provide frequent, direct links that can serve both business travelers and tourists at lower cost. The dataset also uncovers underserved pockets, especially in the West, where coverage is sparse and service reliability varies. For investors and transit planners, the map offers a data‑driven foundation to identify high‑potential corridors for service upgrades or public‑private partnerships.

In Washington state, the Washington State Department of Transportation (WSDOT) has leveraged the study’s insights to expand its subsidized intercity network. The Apple, Dungeness, Gold and Grape lines now run two to three daily trips, and the upcoming Wheat Line will connect Spokane, Moses Lake and Pasco by spring 2026. These enhancements directly address gaps highlighted in the 2024 Travel Washington Intercity Bus Program Study, improving connectivity for smaller communities and supporting regional economic development. Continued investment in these routes could further close the mobility gap between urban cores and outlying areas, positioning buses as a critical complement to the nation’s limited passenger‑rail infrastructure.
