Abstract

An impact tracking system includes a sensor module that mounts to a fixed crash attenuator, sign, guardrail, or other roadway devices installed along a roadway. When the crash attenuator or other asset is impacted by an errant vehicle, the impact tracker, comprising a sensor system, senses and captures the impact data and sends an alert message to a remote receiver. The receiver may comprise known data receiving means, such as computers or phone systems, which may receive emails, text messages, photos, and the like in real or near real time. Received data may be analyzed, stored, and/or re-transmitted to additional receivers, which may include road authorities, such as transportation departments responsible for inspecting and repairing the impact attenuators.

First claim

What is claimed is:

1. A tracking and management system for roadway traffic safety assets, comprising:
a sensor module securable to a particular asset, the sensor module comprising a housing which encloses a processor, a communications transmitter, a power supply, and an impact detecting sensor; and
a communications receiver remote from the sensor module, the communications receiver being adapted to receive a signal from the communications transmitter and to log information related to the signals into a database containing identifying information concerning the sensor module and the particular asset to which the sensor module is secured, the communications receiver further being adapted to display identifying information concerning the particular asset and the sensor module secured thereto, the signal from the communications transmitter being triggered by an impact above a predetermined level sensed by the impact detecting sensor;
the communications receiver comprising a host server, the host server having a database for storing information regarding the particular asset and the sensor module secured to the particular asset, the communications receiver further being adapted to display a dashboard presenting impact and management information regarding the particular asset and sensor module secured thereto, the dashboard being displayable on a screen directly connected to the host server, and/or being displayable on screens of other devices logged into the host server and having suitable application software installed thereon;
wherein the predetermined level sensed by the impact detecting sensor is adjustable by a user.

2. The tracking and management system as recited in claim 1 , wherein the signal from the communications transmitter comprises an alarm.

3. The tracking and management system as recited in claim 2 , wherein the impact detecting sensor comprises an accelerometer.

4. The tracking and management system as recited in claim 2 , wherein the predetermined impact level triggering the impact detecting sensor is set to detect a likely damaging impact on the particular asset by a vehicle.

5. The tracking and management system as recited in claim 4 , wherein the predetermined impact level is 0.5G on an X-Y axis and 1.0G on a Z axis.

6. The tracking and management system as recited in claim 1 , wherein the processor comprises a low power cellular module.

7. The tracking and management system as recited in claim 6 , wherein the communications transmitter comprises a cellular antenna.

8. The tracking and management system as recited in claim 1 , wherein the sensor module further comprises a GPS locator.

9. The tracking and management system as recited in claim 1 , wherein the power supply comprises a battery.

10. The tracking and management system as recited in claim 1 , and further comprising a scannable identifier on the sensor module housing for providing a user with immediate information concerning the sensor module and the sensor module's associated asset.

11. The tracking and management system as recited in claim 10 , wherein the scannable identifier comprises a QR code.

12. The tracking and management system as recited in claim 1 , wherein the dashboard is adapted to display a slider for tuning the impact detecting sensor to adjust the predetermined level sensed by the impact detecting sensor.

13. The tracking and management system as recited in claim 1 , and further comprising a manual power switch enclosed within the housing of the sensor module.

14. A tracking and management system for roadway traffic safety assets, comprising:
a sensor module securable to a particular asset, the sensor module comprising a housing which encloses a processor, a communications transmitter, a power supply, and an impact detecting sensor;
a communications receiver remote from the sensor module, the communications receiver being adapted to receive a signal from the communications transmitter and to log information related to the signals into a database containing identifying information concerning the sensor module and the particular asset to which the sensor module is secured, the communications receiver further being adapted to display identifying information concerning the particular asset and the sensor module secured thereto;
the communications receiver comprising a host server, the host server having a database for storing information regarding the particular asset and the sensor module secured to the particular asset, the communications receiver further being adapted to display a dashboard presenting impact and management information regarding the particular asset and sensor module secured thereto, the dashboard being displayable on a screen directly connected to the host server, and/or being displayable on screens of other devices logged into the host server and having suitable application software installed thereon; and
a scannable identifier on the sensor module housing for providing a user with immediate information concerning the sensor module and the sensor module's associated asset;
wherein the scannable identifier is adapted to direct a device scanning the scannable identifier to the dashboard.

15. A method of tracking and managing roadway traffic safety assets using sensor modules secured to or otherwise associated with each asset to be tracked and managed, comprising:
receiving an activation signal from a sensor module secured to a particular asset;
logging the sensor module and the particular asset into a database, including information identifying the particular asset, the particular asset's location, and a customer responsible for the particular asset; and
receiving and logging an alarm signal from the sensor module, indicating that an impact above a threshold value has been detected on the particular asset;
forwarding information concerning the alarm signal to the customer responsible for the particular asset; and
displaying information concerning the particular asset to a logged-in user when the logged-in user scans an identifier disposed on the sensor module, the displayed information including control functions which permit the logged-in user to manage the particular asset.

16. The method as recited in claim 15 , wherein the forwarding step comprises forwarding information to a customer's mobile or computer device.

17. The method as recited in claim 15 , and further utilizing an accelerometer to detect the impact above a threshold value.

18. The method as recited in claim 15 , and further displaying a status for each of a plurality of assets upon receipt of an inquiry from a logged-in user.

19. The method as recited in claim 15 , and further comprising a step of receiving and logging photographs of the particular asset into the database.

20. The method as recited in claim 19 , wherein the step of receiving and logging photographs of the particular asset into the database occurs after receipt of an alarm signal concerning the particular asset, the method further comprising reviewing the logged photographs to ascertain any damage to the particular asset requiring repair or replacement.

21. The method as recited in claim 20 , and further comprising a step of adding an indicator in the database that a particular asset is damaged, the indicator being displayed to a logged-in user viewing information from the database to advise the logged-in user of a need to repair or replace the particular asset.

22. A method of tracking and managing roadway traffic safety
