The invention provides for an automated computerized ground transportation service reservation system (10) linking vendors of ground transportation services (12) and agents selling round transportation services (16). Ground transportation service reservation requests (30) are received from the agents (16) and distributed to the vendors (12) for fulfillment through the ground transportation reservation system (10) of the invention. The availability of vendors (12) to fulfill requests for ground transportation services (30) is maintained by the respective vendors (12) on a computer system at their locations. In the preferred environment, "switches" (82) on the screen display of each vendor's computer system indicate its availability, and each vendor's availability is "mirrored" onto storage on a ground transportation reservation system server (10) so that the server (10) can make reservations as requests (30) are received from the agents. Automated dispatching and billing are also provided for through the ground transportation reservation system (10) of the invention.
