Public transit vehicle arrival information system
First Claim
1. An interactive information and control system for transit vehicles in a transit system, comprising:
- (1) a global positioning system device located in selected transit vehicles in the transit system for monitoring the position of said transit vehicles;
(2) a system computer, (a) storing an historical transit data table containing transit vehicle schedules of the travel times necessary for said transit vehicles to move from one stop to another along their routes under different conditions, advertisements, and information for the operators and passengers of said transit vehicles, (b) selecting from said historical transit data table a schedule of travel times applicable for current conditions along a given route, and (c) using said schedule of travel times from said historical transit data table and said position of said transit vehicles at a given time to calculate predicted arrival and departure times at which said transit vehicles will arrive and depart at upcoming stops and incorporating said predicted arrival and departure times in a predicted transit data table;
(3) means communicating between said global positioning system device and said system computer for transmitting said position of said transit vehicles to said system computer;
(4) means broadcasting said predicted transit data table within the area served by the transit system; and
(5) receivers selected from any member of the group consisting of portable receivers, receivers at selected locations such as vehicle stops, and receivers on board said transit vehicles within the transit system, said receivers adapted for receiving said broadcast and displaying at least subsets of said predicted transit data table associated with said selected receivers, including subsets containing at least one of said predicted arrival and departure times, said advertisements, and said information for said operators and passengers of said transit vehicles.

Abstract
A system for notifying passengers waiting for public transit vehicles of the status of the vehicles, including the arrival times of vehicles at stops. The system includes global position determining devices located in the vehicles for determining the location of the vehicles along their routes. A central processor or computer is coupled to the global position determining devices for receiving the locations of vehicles therefrom. The processor is programmed to compute and update from the present location of the transit system vehicles and electronically stored information a transit data table which includes status information for all the vehicles in the system, including the location of scheduled stops, connections to other transit vehicles at the stops, and the arrival times of vehicles at their stops. The vehicle status and other information, including news and advertisements are then made available for public access in a manner geared to the locations of the vehicles, the time of day, day of week, date, location, season, holiday, weather etc. Portable access means such as pagers, notebook and palm computers and telephones and stationary access means such as personal computers and telephones, and display modules in communication with the central processor, receive the computed arrival time and other information for selected routes, stops, etc. from the central processor, and communicate the information to the passenger(s).
