A method for routing a vehicle for hire includes receiving a request to pick up a passenger at a predetermined time. Information indicating a first location of the passenger is received. The vehicle is routed to the first location at the calculated dispatch time. Information indicating a second location of the passenger is received. It is determined whether the second location jeopardized a timely pickup. The vehicle is rerouted to the second location when it is determined that the second location does not jeopardize the timely pickup. A notification is sent to the passenger warning that the second present location jeopardizes the timely pickup and the passenger is provided with directions on how to move to a location that does not jeopardize the timely pickup when it is determined that the second location of the passenger does jeopardize the timely pickup.
