Abstract

An autonomous apparatus for generating real-time estimates of the time of arrival of vehicles at user selected sites. The apparatus is comprised of two separate components, a vehicle unit which is carried by each vehicle and a user unit which is carried by each user. The vehicle unit determines time and geographical position at predetermined locations and broadcast these data to the user units through a wireless communications medium. The user unit receives the time and position information and adds it to computer memory records of similar data received over a prior period of time. The combined set of recorded data is used to estimate the time that the broadcasting vehicle will arrive at a specific location, that location having been specified by the user on a previous occasion by pressing a button on the user unit when the vehicle was stopped at the selected location. The estimated arrival time is presented on a display. The system operates without any assistance or information input from humans and its user require no special knowledge or skills. It is ideally suited for application to school bus transportation services.
