Abstract
Abstract The invention relates to a waiting time prediction system for visualizing waiting times until the arrival of at least one vehicle (2), in particular a vehicle of the public transit system, at at least one station stop (5). Hardware and/or software expenses are minimized by including the following components: a first device for determining position data of the vehicle (2), a second device for calculating the remaining expected driving time until the arrival of the vehicle (2) at the station stop (5) based on the measured position data of the vehicle (2) and the known coordinates of the station stop (5), and first and second transmission means for transmitting information from the first device to the second device and from the second device to a station stop display (4), wherein the station stop display (4) can be controlled by this second transmission means to indicate the waiting time.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
160 words
A waiting time prediction system for visualizing waiting times until the arrival of at least one vehicle (2), in particular a vehicle of the public transit system, at at least one station stop (5), characterized by a first device for determining position data of the vehicle (2), a second device for calculating the remaining expected driving time until arrival of the vehicle (2) at the station stop (5) based on the measured position data of the vehicle (2) and the known coordinates of the station stop (5), first and second transmission means for transmitting information from the first device to the second device and from the second device to a station stop display (4), wherein the station stop display (4) can be controlled by the second transmission means to indicate the waiting time, and an external read-only monitoring station (19) connected to a center location (3) via ISDN (16) or via the Internet for monitoring purposes, including remote malfunction diagnostics.
Claim 2
Dependent Claim
160 words
A waiting time prediction system for visualizing waiting times until the arrival of at least one vehicle (2), in particular a vehicle of the public transit system, at at least one station stop (5), characterized by a first device for determining position data of the vehicle (2), a second device for calculating the remaining expected driving time until arrival of the vehicle (2) at the station stop (5) based on the measured position data of the vehicle (2) and the known coordinates of the station stop (5), first and second transmission means for transmitting information from the first device to the second device and from the second device to a station stop display (4), wherein the station stop display (4) can be controlled by the second transmission means to indicate the waiting time, and an external read-only monitoring station (19) connected to a center location (3) via ISDN (16) or via the Internet for monitoring purposes, including remote malfunction diagnostics.
Claim 3
Dependent Claim
22 words
A waiting time prediction system according to claim 1, characterized in that the first device comprises radio means, in particular position beacons.
Claim 4
Dependent Claim
26 words
