Why do some routes have vehicle numbers and others show scheduled time?
Scheduled Time There are several reasons why the Automatic Vehicle Location ( AVL ) system may not be able to predict the actual time that a bus might be arriving. For example, this might occur as a result of a defective AVL unit on a bus, or a bus may have been instructed to detour off-route, or the bus may be out of radio coverage. When our system cannot predict the expected arrival time based on current AVL readings, our HEA system defaults to the scheduled time rather than the estimated time.
