1. A decentralized mass transit rider information system to reduce rider anxiety for use in a mass transit system having a route traveled by at least one mass transportation vehicle in accordance with a posted schedule and having at least one stop on said route visited by said vehicle during that schedule, comprising:
- a first stationary unit for placement at a first stop, the first stationary unit having a first receiving unit, a first display unit and a first timer unit coupled to said first receiving unit;
the first receiving unit, the first display unit and the first timer unit being proximally associated with said first stationary unit for placement at said first stop;
the first receiving unit having means for issuing a first command signal to said first timer unit the first timer unit and first display unit being responsive to said first command signal to repeatedly measure and display a first numerical value indicative of the current elapsed time following receipt of said first command signal;
a second stationary unit for placement at a second stop, the second stationary unit having a second receiving unit, a second display unit and a second timer unit coupled to said second receiving unit;
the second receiving unit, the second display unit and the second timer unit being proximally associated with said second stationary unit for placement at said second stop;
the second receiving unit having means for issuing a second command signal to said second timer unit the second timer unit and second display unit being responsive to said second command signal to repeatedly measure and display a second numerical value indicative of the current elapsed time following receipt of said second command signal;
a vehicle unit for placement on said vehicle, the vehicle unit having a transmitting unit for causing said first and second receiving units to respectively issue first and second command signals to said first and second timer units when the vehicle passes in proximity to said first and second stationary units;
wherein said receiving units include means for discriminating between said first and second command signals based on the respective energy levels of said first and second command signals;
whereby the rider is provided with elapsed time information allowing the rider to estimate the arrival time of the next scheduled vehicle from the posted schedule.

Abstract
The vehicle-mounted transmitter unit triggers a reset signal in the stationary receiver unit when the vehicle passes in sufficiently close proximity to the stationary unit. A display connected to the stationary unit tells waiting passengers or riders when to expect the next vehicle to arrive, by presenting either time of day at which last vehicle arrived or elapsed time since last vehicle arrived.

6. A decentralized mass transit rider information system to reduce rider anxiety for use in a mass transit system having a route traveled by at least one mass transportation vehicle in accordance with a posted schedule and having at least one stop on said route visited by said vehicle during that schedule, comprising:
-
a first stationary unit for placement at a first stop, the first stationary unit having a first receiving unit, a first display unit and a first timer unit coupled to said first receiving unit;
the first receiving unit, the first display unit and the first timer unit being proximally associated with said first stationary unit for placement at said first stop;
the first receiving unit having means for issuing a first command signal to said first timer unit, and the first resettable timer unit having a first time of day capturing mechanism for determining and storing a first time of day in response to said first command signal;the first timer unit and first display unit being responsive to said first command signal to repeatedly calculate from said first time of day and display a first numerical value indicative of the current elapsed time following receipt of said first command signal; a second stationary unit for placement at a second stop, the second stationary unit having a second receiving unit, a second display unit and a second timer unit coupled to said second receiving unit;
the second receiving unit, the second display unit and the second timer unit being proximally associated with said second stationary unit for placement at said second stop, the second receiving unit having a second time of day capturing mechanism for determining and storing a second time of day in response to said second command signal;the second timer unit and second display unit being responsive to said second command signal to repeatedly calculate from said second time of day and display a second numerical value indicative of the current elapsed time following receipt of said second command signal; a vehicle unit for placement on said vehicle, the vehicle unit having a transmitting unit for causing said receiving unit to issue a reset signal to said resettable timer unit when the vehicle passes in proximity to said stationary unit; wherein said receiving units include means for discriminating between said first and second command signals based on the respective energy levels of said first and second command signals; whereby the rider is provided with information regarding the time of last vehicle arrival thereby allowing the rider to estimate the arrival time of the next scheduled vehicle from the posted schedule. - View Dependent Claims (7, 8, 9, 10)

11. A decentralized mass transit rider information system to reduce rider anxiety for use in a mass transit system having a plurality of routes each traveled by at least one mass transportation vehicle in accordance with posted schedules and in which at least two of said routes share a common stop, comprising:
-
first route information station associated with a first route and located at said common stop; second route information station associated with a second route and located at said common stop; each of said information stations having timing system disposed at said station and responsive to a command signal for displaying information regarding the timing of last vehicle arrival at that stop; first transmitter disposed on said vehicle of said first route having means for communicating a first command signal to the timing system of said first route information station, said first command signal being generally coincident with the arrival of said vehicle of said first route at said common stop; second transmitter disposed on said vehicle of said second route having means for communicating a second command signal to the timing system of said second route information station, said second command signal being generally coincident with the arrival of said vehicle of said second route at said common stop; the first and second transmitters supplying first and second command signals as differently coded signals; whereby said receiving unit includes means for discriminating between said first command signal and said second command signal based on the respective energy levels of said first and second command signals and further based on coding differences between the first and second signals, and whereby the rider is provided with last vehicle arrival time information for both routes sharing said common stop, thereby allowing the rider to estimate the arrival time of the next scheduled vehicle from the posted schedule. - View Dependent Claims (12, 13, 14, 15)
