Abstract

An example operation includes one or more of directing a group of connected vehicles to occupy one or more lanes approaching an intersection and notifying one of the connected vehicles to exit the group using another of the one or more lanes prior to the intersection.

Claims (59)

1. A method, comprising:

directing a group of connected vehicles to occupy one or more lanes approaching an intersection;

determining a distance between a first vehicle and a second vehicle of the group of connected vehicles ahead of the first vehicle and in a same lane;

determining the distance results in a speed reduction of the first vehicle; and

notifying the second vehicle to increase the distance from the first vehicle.

2. The method of claim 1 , wherein directing the group of connected vehicles to occupy one or more lanes approaching the intersection comprises:

directing one or more other vehicles ahead of the first vehicle to occupy a different lane than a lane including the first vehicle.

3. The method of claim 1 , comprising:

determining one of the connected vehicles is ahead of, in the same lane as, and traveling at a slower speed than the first vehicle of the group of connected vehicles; and

notifying the one of the connected vehicles to exit the group of connected vehicles.

4. The method of claim 1 , comprising:

determining a destination for each vehicle of the group of connected vehicles; and

notifying each vehicle of the group of connected vehicles to occupy a lane of the one or more lanes and a speed of each vehicle to maintain as each vehicle travels to the destination.

5. The method of claim 1 , comprising:

determining one or more vehicles of the group of connected vehicles are traveling at a higher speed than other vehicles of the group of connected vehicles and are more than a distance away from the first vehicle of the group of connected vehicles; and

assigning the one or more vehicles to a different group of connected vehicles.

6. The method of claim 1 , comprising:

determining a timing of a traffic signal at the intersection; and

notifying the first vehicle of the group of connected vehicles and any other connected vehicle in the same lane as, and traveling at a slower speed than the first vehicle, of a speed to maintain related to the timing.

7. A system, comprising:

a processor; and

a memory, coupled to the processor, comprising instructions that when executed by the processor are configured to:

direct a group of connected vehicles to occupy one or more lanes that approach an intersection;

determine a distance between a first vehicle of the group of connected vehicles and a second vehicle of the group of connected vehicles ahead of the first vehicle and in a same lane;

determine the distance results in a speed reduction of the first vehicle; and

notify the second vehicle to increase the distance from the first vehicle.

8. The system of claim 7 , wherein the processor directs the group of connected vehicles to occupy one or more lanes that approach the intersection comprises the instructions are configured to:

direct one or more other vehicles ahead of the first vehicle to occupy a different lane than a lane that includes the first vehicle.

9. The system of claim 7 , wherein the instructions are configured to:

determine one of the connected vehicles is ahead of, in the same lane as, and travels at a slower speed than the first vehicle of the group of connected vehicles; and

notify the one of the connected vehicles to exit the group of connected vehicles.

10. The system of claim 7 , wherein the instructions are configured to:

determine a destination for each vehicle of the group of connected vehicles; and

notify each vehicle of the group of connected vehicles to occupy a lane of the one or more lanes and a speed of each vehicle to maintain as each vehicle travels to the destination.

11. The system of claim 7 , wherein the instructions are configured to:

determine one or more vehicles of the group of connected vehicles that travel at a higher speed than other vehicles of the group of connected vehicles and are more than a distance away from the first vehicle of the group of connected vehicles; and

assign the one or more vehicles to a different group of connected vehicles.

12. The system of claim 7 , wherein the instructions are configured to:

determine a timing of a traffic signal at the intersection; and

notify the first vehicle of the group of connected vehicles and any other vehicle in the same lane as, and travels at a slower speed than the first vehicle, of a speed to maintain related to the timing.

13. A computer readable storage medium comprising instructions, that when read by a processor, cause the processor to perform:

directing a group of connected vehicles to occupy one or more lanes approaching an intersection;

determining a distance between a first vehicle and a second vehicle of the group of connected vehicles ahead of the first vehicle and in a same lane;

determining the distance results in a speed reduction of the first vehicle; and

notifying the second vehicle to increase the distance from the first vehicle.

14. The computer readable storage medium of claim 13 , wherein directing the group of connected vehicles to occupy one or more lanes approaching the intersection comprises the instructions cause the processor to perform:

directing one or more other vehicles ahead of the first vehicle to occupy a different lane than a lane including the first vehicle.

15. The computer readable storage medium of claim 13 , wherein the instructions cause the processor to perform:

determining one of the connected vehicles is ahead of, in the same lane as, and traveling at a slower speed than the first vehicle of the group of connected vehicles; and

notifying the one of the connected vehicles to exit the group of connected vehicles.

16. The computer readable storage medium of claim 13 , wherein the instructions cause the processor to perform:

determining a destination for each vehicle of the group of connected vehicles; and

notifying each vehicle of the group of connected vehicles to occupy a lane of the one or more lanes and a speed of each vehicle to maintain as each vehicle travels to the destination.

17. The computer readable storage medium of claim 13 , wherein the instructions cause the processor to perform:

determining one or more vehicles of the group of connected vehicles are traveling at a higher speed than other vehicles of the group of connected vehicles and are more than a distance away from the first vehicle of the group of connected vehicles; and

assigning the one or more vehicles to a different group of connected vehicles.

18. The computer readable storage medium of claim 13 , wherein the instructions cause the processor to perform:

determining a timing of a traffic signal at the intersection; and

notifying the vehicle of the group of connected vehicles and any other vehicle in the same lane as, and traveling at a slower speed than the first vehicle, of a speed to maintain related to the timing.
