Abstract

A method for smart broadcasting of stop names includes the steps of using a global positioning device to receive positioning signals transmitted from a satellite to obtain data of current vehicle geographic longitude and latitude coordinates and moving speed, and to compute a distance between the current vehicle position and a next stop based on the obtained current vehicle coordinates and moving speed data; and causing a microprocessor to use analyzed vehicle speed data to compute parameters for adjusting a predicted distance and the predicted distance, so that the microprocessor determines based on the predicted distance and the distance to the next stop whether a broadcasting device is to be actuated or not. Therefore, a mass transportation vehicle running on the same route at different hours in a day may automatically broadcast and timely inform passengers of the next stop name depending on the current vehicle moving speed.
