Mixed Mode Transit Systems

NAICS 485111 · Transit and Ground Passenger Transportation · SBA size standard: $29 million average annual receipts

Mixed mode transit systems operate scheduled passenger services that combine multiple modes such as bus, van, rail shuttle and demand-response vehicles on shared routes and timetables. The specialists turn rider bookings and agency schedules into daily dispatch plans, track vehicle and driver availability, generate required manifests and logs, manage fare and billing reconciliation, and maintain compliance paperwork for DOT, FTA and local transit authorities. Scheduling, permits, vehicle inspections, driver licensing, fuel and parts inventory, asset maintenance and customer communications stay with operations staff.
