Abstract

A method of performing collision prevention and a system to perform collision prevention involve a communication interface to receive information from connected devices of individuals. The system also includes a processor to obtain the information from the connected devices, estimate a potential for an upcoming collision, and issue an alert based on the potential for the upcoming collision to one or more of the connected devices.

Claims

1. A collision prevention system, comprising:

a plurality of connected devices, each of the plurality of connected devices being configured to determine, by using a location and a movement of the connected device, whether the connected device is a road user connected device that is used on a roadway or in motion on a sidewalk;

a communication interface configured to receive information from only the road user connected devices among the plurality of connected devices; and

a processor configured to obtain the information from only the road user connected devices, estimate a potential for an upcoming collision, and issue an alert based on the potential for the upcoming collision to one or more of the road user connected devices.

2. The system according to claim 1, wherein the communication interface is further configured to receive other information from other sources additional to the road user connected devices of the individuals.

3. The system according to claim 2, wherein the other information includes weather information.

4. The system according to claim 2, wherein the other information includes infrastructure information indicating traffic light information.

5. The system according to claim 2, wherein the other information includes road condition information.

6. The system according to claim 1, wherein the communication interface is configured to receive the information indicating a classification of the vehicle based on the road user being the driver of the vehicle.

7. The system according to claim 1, wherein the communication interface is configured to receive location, speed, and heading from each of the road user connected devices.

8. The system according to claim 1, wherein the processor is further configured to develop a digital map from the information.

9. The system according to claim 8, wherein the processor is further configured to estimate the potential for the upcoming collision based on the digital map and issue the alert to one or more road user connected devices corresponding with the potential collision.

10. A method of performing collision prevention, the method comprising:

for each of a plurality of connected devices, determining, using a location and a movement of the connected device, whether the connected device is a road user connected device that is used on a roadway or in motion on a sidewalk;

receiving, at a central controller, information from only the road user connected devices among the plurality of connected devices; and

estimating, at the central controller, a potential for an upcoming collision based on the information; and

issuing an alert, from the central controller, based on the potential for the upcoming collision.

11. The method according to claim 10, further comprising receiving, at the central controller, other information from other sources additional to the road user connected devices of the individuals.

12. The method according to claim 11, wherein the receiving the other information includes receiving weather information.

13. The method according to claim 11, wherein the receiving the other information includes receiving infrastructure information indicating traffic light information.

14. The method according to claim 11, wherein the receiving the other information includes receiving road condition information.

15. The method according to claim 10, wherein the receiving the information includes receiving the information indicating a classification of the vehicle based on the road user being the driver of the vehicle.

16. The method according to claim 10, wherein the receiving the information includes receiving the information indicating location, speed, and heading from each of the road user connected devices.

17. The method according to claim 10, further comprising developing a digital map from the information.

18. The method according to claim 17, wherein the estimating the potential for the upcoming collision is based on the digital map and issuing the alert is to one or more road user connected devices corresponding with the potential collision.
