Computerized dispatching system
First Claim
1. An automatic dispatching system for a fleet of independently driver-operated vehicles serving a predetermined area with a multiplicity of potential stops for said vehicles at fixed locations, comprising:
- centralized computer means;
station equipment at each of said locations linked by a telecommunication channel with said computer means, said equipment including a destination selector operable by prospective passengers; and
information means aboard each vehicle in communication with said computer means, said information means including a register for the entry of stop identifications representing the destinations of passengers boarding the vehicle and station-indicating means for giving routing instructions to the driver of the vehicle, said computer means including logical circuitry and decision stages of a general-purpose computer programmed to evaluate data from the destination selectors at all said locations and from the registers aboard all said vehicles for operating said station-indicating means to route each vehicle to stops requiring service, while skipping stops not entered in the register thereof unless the destination selector at such stop is operated to report a prospective passenger, by the steps of(a) determining whether any passenger aboard a given vehicle has the next stop as a destination,(b) determining whether passengers are waiting at said next stop with destinations along the route traveled by said given vehicle,(c) determining, upon a positive determination in step (b), whether said next stop is being served by another vehicle traveling the same route and having available space for said waiting passengers,(d) upon a negative determination in step (a), and either a negative determination in step (b) or a positive determination in step (c), instructing the driver of said given vehicle to bypass said next stop.

Abstract
A passenger buys his ticket at a station from a device which registers his destination and transmits the information to a central computer using the destination data to plot a travel path for a fleet of buses or other mass-transit vehicles. The arrival time of the next vehicle is indicated at each station; as the user boards such vehicle his destination is entered in a register therein. The central computer reads the vehicular memories by radio communication to modify, if necessary, the instructions given to the driver. Traffic density, average vehicular speed and the rhythm of traffic lights are also read into the central computer by way of supplemental information.
