identifying, based on the remote vehicle information and the host vehicle information, a queue length representing a number of the queued vehicles that are queued ahead of the host vehicle;

identifying, based on the remote vehicle information and the host vehicle information, at least one of the one or more remote vehicles as a conflicting vehicle that is travelling on a second path that crosses the first path;

determining a time-to-contact based on the remote vehicle information corresponding to the conflicting vehicle and the host vehicle information; and

causing a warning alert to be output if the time-to-contact is less than a warning alert threshold and only if the queue length is zero vehicles.

2. The method of claim 1 , wherein no warning alert is output if the queue length is equal to or greater than one vehicle.

3. The method of claim 1 , wherein causing the warning alert to be output is performed using at least one of an audio output device or a visual output device.

4. The method of claim 1 , further comprising:

causing an informative alert to be output if the time-to-contact is less than an informative alert threshold, the time-to-contact is greater than the warning alert threshold, and only if the queue length is equal to or less than one vehicle.

5. The method of claim 4 , wherein causing the informative alert to be output is performed using at least one of an audio output device or a visual output device.

6. The method of claim 1 , further comprising:

causing an informative alert to be output if the time-to-contact is less than the warning alert threshold, and only if the queue length is equal to one vehicle.

7. The method of claim 6 , wherein causing the informative alert to be output is performed using at least one of an audio output device or a visual output device.

8. The method of claim 1 , wherein receiving remote vehicle information includes receiving a message from each of the one or more vehicles, each message including information regarding the respective one of the one or more vehicles.

9. The method of claim 1 , wherein the geospatial state for the host vehicle and each of the one or more remote vehicles includes geospatial coordinates, and the kinematic state for the host vehicle and each of the one or more remote vehicles includes at least one of a heading, a velocity, or a yaw rate.

10. A vehicle, comprising:

a wireless electronic communication device;

one or more sensors;

an output system including at least one of an audio output device or a visual output device; and

an information system operable to execute instructions that cause the information system to:

receive, from one or more remote vehicles using the wireless communication device, remote vehicle information indicating geo spatial state and kinematic state for each of the one or more remote vehicles,

identify, using the one or more sensors, host vehicle information indicating geospatial state and kinematic state for the host vehicle, wherein the host vehicle is waiting to take an action that includes traversing a first path,

determine, based on the remote vehicle information and the host vehicle information, whether any of the remote vehicles are queued vehicles that are waiting ahead of the host vehicle to take the action that includes traversing the first path,

identify, based on the remote vehicle information and the host vehicle information, a queue length representing a number of the queued vehicles that are queued ahead of the host vehicle,

identify, based on the remote vehicle information and the host vehicle information, at least one of the one or more remote vehicles as a conflicting vehicle that is travelling on a second path that crosses the first path,

determine a time-to-contact based on the remote vehicle information corresponding to the conflicting vehicle and the host vehicle information, and

cause a warning alert to be output if the time-to-contact is less than a warning alert threshold and only if the queue length is zero vehicles.

11. The vehicle of claim 10 , wherein no warning alert is output if the queue length is equal to or greater than one vehicle.

12. The vehicle of claim 10 , wherein causing the warning alert to be output is performed using at least one of an audio output device or a visual output device.

13. The vehicle of claim 10 , further comprising:

causing an informative alert to be output if the time-to-contact is less than an informative alert threshold, the time-to-contact is greater than the warning alert threshold, and only if the queue length is equal to or less than one vehicle.

14. The vehicle of claim 13 , wherein causing the informative alert to be output is performed using at least one of an audio output device or a visual output device.

15. The vehicle of claim 10 , further comprising:

causing an informative alert to be output if the time-to-contact is less than the warning alert threshold, and only if the queue length is equal to one vehicle.

16. The vehicle of claim 15 , wherein causing the informative alert to be output is performed using at least one of an audio output device or a visual output device.

17. The vehicle of claim 10 , wherein receiving remote vehicle information includes receiving a message from each of the one or more vehicles, each message including information regarding the respective one of the one or more vehicles.

18. The vehicle of claim 10 , wherein the geospatial state for the host vehicle and each of the one or more remote vehicles includes geospatial coordinates, and the kinematic state for the host vehicle and each of the one or more remote vehicles includes at least one of a heading, a velocity, or a yaw rate.

19. A method for providing information to a driver of a vehicle, comprising:

receiving, at a host vehicle from one or more remote vehicles via a wireless electronic communication link, remote vehicle information indicating geospatial state and kinematic state for each of the one or more remote vehicles, wherein the kinematic state for each of the one or more remote vehicles includes a remote vehicle heading;

identifying host vehicle information indicating geospatial state and kinematic state for the host vehicle, wherein the kinematic state for each of the one or more remote vehicles includes a host vehicle heading;

determining, based on the remote vehicle information and the host vehicle information, whether any of the remote vehicles are queued vehicles, based in part on the host vehicle heading and the remote vehicle heading for each of the queued vehicles;

identifying, based on the remote vehicle information and the host vehicle information, a queue length representing a number of the queued vehicles that are queued ahead of the host vehicle;

identifying, based on the remote vehicle information and the host vehicle information, at least one of the one or more remote vehicles as a conflicting vehicle, based in part on the host vehicle heading and the remote vehicle heading for the conflicting vehicle;

determining a time-to-contact based on the remote vehicle information corresponding to the conflicting vehicle and the host vehicle information; and

causing a warning alert to be output if the time-to-contact is less than a warning alert threshold and only if the queue length is zero vehicles.

20. The method of claim 19 , wherein the determining whether any of the remote vehicles are queued vehicles is based in part on a difference between the host vehicle heading and the remote vehicle heading for each of the queued vehicles being below a threshold value and identifying, the conflicting vehicle is based in part one a difference between the host vehicle heading and the remote vehicle heading for the conflicting vehicle.
