Abstract
A transportation vehicle alert monitor incorporating a speech synthesizer for voice announcement of vehicle location by stop number. The monitor includes a radio receiver responsive to coded RF signals containing either current vehicle location data or data for programming the monitor. Current location data includes school system number, bus number, route number, and stop number. Programming data includes school system number, monitor serial number, student number, two route numbers for one bus number, and initial and final alert stops for each route. Programability of initial alert stops allows each alert monitor to be remotely adjusted to allow varying conditions including the discharge between adjacent stops, traffic conditions, and distance from a passenger's house to the stop.
