Abstract
Approaches for managing transit vehicle schedules. The method includes determining a current location and current heading of a transit vehicle by a global positioning system (GPS) module aboard the transit vehicle and communicating the current location and current heading to a computer processor. The computer processor determines a current time and current day, and a trip schedule is selected from a plurality of trip schedules in a database. The selected trip schedule has attributes consistent with the current location, current heading, current time, and current day. The method determines whether the transit vehicle is ahead of the selected trip schedule or behind the selected trip schedule. An output signal indicates whether the transit vehicle is ahead of or behind schedule.
