Abstract

A railroad crossing indication device (250) includes a processing unit (350) for receiving and processing data provided by a constant warning time device (40) in communication with a railroad track (20), wherein the data relate to a train approaching the railroad crossing, and a screen unit (300, 400, 500) for displaying information of the train approaching the railroad crossing based upon the data provided by the constant warning time device (40). Furthermore, a railroad crossing indication system (200) and a method (600) for displaying information at railroad crossings are disclosed.

Claims

1. Railroad crossing indication device comprising:

a processing unit configured to receive and process data provided by a constant warning time device in communication with a railroad track, wherein the data relate to a train approaching the railroad crossing; and

a screen unit configured to display information of the train approaching the railroad crossing based upon the data provided by the constant warning time device, and

a memory unit storing a plurality of graphical elements including progress bars,

wherein the screen unit comprises multiple screen sections, a first section of the multiple screen sections displaying a progress bar visualizing progression of the train approaching the railroad crossing, wherein the processing unit is configured to select the progress bar from the plurality of graphical elements.

2. The railroad crossing indication device as in claim 1, wherein the information of the train approaching the railroad crossing is selected from a group consisting of train speed, direction of train, proximity of train, time of arrival of train at the railroad crossing, time a train takes to pass a railroad crossing, and a combination thereof.

3. The railroad crossing indication device as in claim 1, wherein the railroad crossing indication device is located in proximity to the railroad crossing mounted to a support assembly of an existing railroad crossing warning device.

4. A railroad crossing indication system comprising:

a constant warning time device in communication with a railroad track;

at least one railroad crossing warning device located at a railroad crossing in communication with the constant warning time device; and

a railroad crossing indication device located in proximity to the railroad crossing and the at least one railroad crossing warning device, and in communication with the constant warning time device, wherein the railroad crossing indication device displays information relating to a train approaching the railroad crossing based upon data of the train approaching the railroad crossing provided by the constant warning time device,

wherein the railroad crossing indication device comprises a screen unit displaying the information relating to the train approaching the railroad crossing, and a memory unit storing a plurality of graphical elements including progress bars,

wherein the screen unit comprises multiple screen sections, a first section of the multiple screen sections displaying a progress bar visualizing progression of the train approaching the railroad crossing, wherein the processing unit configured to select the progress bar from the plurality of graphical elements.

5. The railroad crossing indication system as in claim 4, wherein the constant warning time device is a grade crossing predictor (GCP) operably coupled to a processing unit of the railroad crossing indication device by connecting elements.

6. The railroad crossing indication system as in claim 4, wherein the railroad crossing indication device is mounted to a support assembly of the at least one railroad crossing warning device.

7. The railroad crossing indication system as in claim 4, wherein the information of the train approaching the railroad crossing is selected from a group consisting of train speed, direction of train, proximity of train, time of arrival of train at the railroad crossing, time the train takes to pass the railroad crossing, and a combination thereof.

8. The railroad crossing indication system as in claim 4, the railroad crossing indication device further comprising:

a processing unit configured to receive and process data provided by the constant warning time device, wherein the data relate to the train approaching the railroad crossing.

9. A method for displaying information at a railroad crossing comprising:

providing data by a constant warning time device which is in communication with a railroad track, the data relating to a train approaching a railroad crossing;

receiving and processing the data by a processing unit a railroad crossing indication device located in proximity to the railroad crossing and operably coupled to the constant warning time device; and

displaying, by a screen unit of the railroad crossing indication device, information of the train approaching the railroad crossing using the data provided by the constant warning time device,

wherein the screen unit comprises multiple screen sections, a first section of the multiple screen sections displaying a progress bar visualizing progression of the train approaching the railroad crossing, wherein the processing unit is configured to select the progress bar from a plurality of graphical elements stored in a memory unit of the railroad crossing indication device.

10. The method as in claim 9, wherein the information of the train approaching the railroad crossing is selected from a group consisting of train speed, direction of train, proximity of train, time of arrival of train at the railroad crossing, time the train takes to pass the railroad crossing, and a combination thereof.

11. The method as in claim 10, wherein the additional information comprises advertisement, news, movies, weather conditions, time information, and a combination thereof.
