Definitions

  • the present invention relates to a mass-transit communication system and more particularly to such a system for controlling and updating information announced to passengers in mass-transit vehicles along vehicle routes.
  • One existing system for relaying information to passengers about bus location incorporates a display sign within the bus which displays the location of the next stop that the bus will make.
  • the system uses stopping place transmitters (sometimes called encoder transmitters or beacons) which are located on utility poles or the like along the bus route.
  • the stopping place transmitters transmit stopping place codes to the display unit within the bus.
  • the display unit within the bus receives the stopping place codes and compares the codes with a pre-stored list of codes in a memory. If the transmitted stopping place code matches one of the pre-stored list of codes in memory, that location is displayed on the display sign to alert: the passengers of the next stop.
  • the stopping place transmitters have a transmission range on the order of several blocks so that a bus will be within the range of the stopping place transmitter only when it is about to make that particular stop.
  • a mass-transit communication system for use in a vehicle which travels along at least one route and for announcing advertising information to passengers on said vehicle.
  • the system comprises memory means in said vehicle for storing advertising information to be announced to passengers in said vehicle, a plurality of location indicating stations located generally along said vehicle route for transmitting location indicating signals, and receiver means in said vehicle for receiving location signals from said location indicating transmitters only when within a predefined communication range.
  • Message announcement means are provided within the vehicle for announcing selected advertising information to passengers on said vehicle in dependence on the location signal received, whereby local advertising information may be displayed which is keyed to the particular geographical location of the vehicle along its route.
  • a mass- transit communication system for communicating information to least one vehicle which travels along at least one route and announcing said information to passengers on said vehicle.
  • the system comprises a plurality of update communication stations located generally along the vehicle route, central control means for transmitting update information to said update communication stations, with said update communication stations having means for transmitting update information to vehicles located within a defined communication range generally proximate to respective update communication stations.
  • Receiver means are located in each vehicle for receiving update information from the update communication station when the vehicle is within the defined range.
  • Message announcement means are located within each vehicle for announcing update information to passengers traveling in the vehicle.
  • the message announcement means preferably comprises means for displaying the update information.
  • the system according to the present invention can be used any place where the audience needs periodic update information, particularly where the audience congregates for a mean time on the order of 5 to 30 minutes, for example.
  • the system according to the invention will be further described herein as it relates to a bus mass-transit system, but it is to be understood that other such applications include trains or similar public transportation systems such as tramways, subways, subway stations, airports and even amusement parks.
  • the present invention provides means for generating advertising revenue to offset and even exceed the cost of implementing such a system.
  • advertising can be sold which would be displayed in the normal display cycle of 5 to 30 minutes along the entire bus route period.
  • advertising can be keyed to particular geographical areas and will reach the very target audience where the advertising will have its greatest impact, namely those persons riding along the segment of the bus route to and from work for example, which are already on the route.
  • advertising revenue can be generated because an advertiser would likely pay more for say 5 total minutes of advertising which targets a particular geographical area than 5 minutes worth of advertising spread over the entire bus route covering a much larger and thus much less effective means of reaching his audience of interest.
  • advertising can be targeted to the ten separate areas and each advertising spot of say 10 or 15 seconds within the 5 to 30 minute display cycle can be sold for each of the ten geographical areas the bus passes through.
  • An advertiser can also contract for one or more routes for only a particular time of the day.
  • the invention also provides means for updating information supplied to the vehicle along the route. Therefore, timely news bulletins can be relayed to passengers within minutes of a news event, updated weather reports can be displayed, and traffic information can be displayed, such as expected delays in minutes or the necessity that the bus take an alternate route due to excessive traffic or emergency conditions.

Abstract

Système de communication et d'affichage d'informations actualisées pour véhicules, par exemple des bus, en cours de trajet. Le système possède une pluralité de stations de communication actualisée disposées le long du trajet du véhicule pour transmettre des informations actualisées, reçues d'un central de contrôle, aux véhicules lorsqu'ils passent devant ces stations. Des récepteurs placés dans les véhicules reçoivent et affichent l'information sur un écran dans ces véhicules. L'information peut concerner une publicité relative à cette partie du trajet, des nouvelles actualisées ou des renseignements sur le temps ou la circulation. Le système comprend également des émetteurs indiquant un emplacement ou un arrêt, commandant au véhicule d'afficher une information relative à l'emplacement où se trouve le véhicule, en réponse à des codes qu'ils reçoivent des émetteurs, identifiant l'emplacement du véhicule.
