Monitoring of route and schedule adherence |
摘要 |
A method for monitoring the movement of a vehicle along a selected route R to determine whether the vehicle is (i) adhering to that route and/or (ii) adhering to a selected time schedule along that route. Adherence to the route R requires that the vehicle travel within a corridor of selected positive width that surrounds a path defining the route R. Adherence to the time schedule requires that the vehicle move past one or more specified locations along or adjacent to the route R within a specified time interval. The method provides an electronic map with a visually perceptible display that indicates the present location of the vehicle and allows implementation of a snap-to-route command that displays the location on the route R that is closest to the present location of the vehicle.
