Hierarchical integrated traffic management system for managing vehicles

1. A system for managing vehicles comprising:

a plurality of first level managers;

a plurality of second level managers each being in a higher hierarchical level than the plurality of first level managers and managing a section; and

a plurality of third level managers each being in a higher hierarchical level than the plurality of second level managers managing an area greater than the section, wherein:

each of the first level managers is configured to:

collect first data using one or more sensors of a vehicle; and

transmit a first instruction to the vehicle based on the first data, and one of the plurality of second level managers is configured to:

receive second data from one or more of the first level managers; and

transmit a second instruction to the vehicle based on the second data, one of the plurality of third level managers is configured to:

receive third data from one or more of the plurality of second level managers in the area managed by the one of the plurality of third level managers; and

transmit a third instruction to the vehicle based on the third data, and

wherein an actuator of the vehicle controls operations of the vehicle based on at least one of the first instruction, the second instruction, and the third instruction.

2. The system of claim 1 , wherein a frequency of collecting the first data is higher than a frequency of obtaining the second information.

3. The system of claim 1 , wherein the first data includes at least one of images captured by one or more imaging sensors of the vehicle, a location of the vehicle, a speed of the vehicle, and an acceleration of the vehicle, and

the second data includes at least one of feature information of other vehicles, and feature information about a road event.

4. The system of claim 3 , wherein the feature information about the road event includes a locations of a construction site, a vehicle accident, an emergency vehicle, or a law enforcement vehicle.

5. The system of claim 1 , wherein the third data includes at least one of vehicle dynamics and road event information in the section managed by corresponding second level manager.

6. The system of claim 1 , wherein the vehicle is a connected and autonomous vehicle.

7. The system of claim 1 , wherein one of the plurality of second level managers manages a first section, and another of the plurality of second level managers manages a second section adjacent the first section,

the third data of the one of the plurality of second level managers is shared with another of the plurality of second level managers, and

the another of the plurality of second level managers determines a second instruction to a vehicle in the second section based on the third data of the one of the plurality of second level managers.

8. The system of claim 1 , wherein abstracted third data includes lane-level traffic information in the area managed by one of the plurality of third level managers, and

the third instruction includes an instruction on lane-level dynamic routing in the area managed by one of the plurality of third level managers.

9. The system of claim 1 , further comprising:

a plurality of fourth level managers each being in a higher hierarchical level than the plurality of third level managers and managing a region greater than the area, wherein:

one of the plurality of fourth level managers is configured to:

receive fourth data from one or more of the plurality of third level managers in the region managed by the one of the plurality of fourth level managers; and

transmit a fourth instruction to the vehicle based on the fourth data.

10. The system of claim 9 , wherein abstracted fourth data includes link-level traffic information, and

the fourth instruction includes a rerouting instruction in a region managed by one of the plurality of fourth level managers.

11. The system of claim 9 , further comprising:

a data center in a higher hierarchical level than the plurality of fourth level managers, wherein:

the data center is configured to:

receive fifth data from the plurality of fourth level managers;

store user preferences;

determine a fifth instruction based on the fifth data and user preferences; and

transmit the fifth instruction to the vehicle.

12. The system of claim 11 , wherein the fifth instruction includes a departure time suggestion or a transportation mode suggestion.

13. The system of claim 11 , wherein the user preferences include at least one of preferred departure times, transportation modes, and objectives of trips.

14. The system of claim 11 , wherein the data center is configured to:

store system preferences; and

determine the fifth instruction further based on the system preferences.

15. The system of claim 14 , wherein the system preferences include at least one of travel time optimization of vehicles, energy minimization, and congestion alleviation.

16. A method for managing vehicles, the method comprising:

collecting, by a first level manager, first data using one or more sensors of a vehicle;

transmitting, by the first level manager, second data to a second level manager, the second level manager being in a higher hierarchical level than the first level manager;

transmitting, by the first level manager, a first instruction to the vehicle based on the first data;

transmitting, by the second level manager, a second instruction to the vehicle based on the second data;

receiving, by a third level manager, third data from the second level manager;

transmitting, by the third level manager, a third instruction to the vehicle based on the third data, wherein the third instruction is different from the second instruction,

wherein the third data includes lane-level traffic information in an area managed by the third level manager, and

an actuator of the vehicle controls operations of the vehicle based on at least one of the first instruction, the second instruction, and the third instruction.

17. The method of claim 16 , further comprising:

receiving, by a fourth level manager, fourth data from the third level manager;

transmitting, by the fourth level manager, a fourth instruction to the vehicle based on the fourth data,

wherein the third instruction includes an instruction on lane-level dynamic routing in the area managed by the third level manager, and

the fourth instruction includes a rerouting instruction in a region managed by the fourth level manager.

18. The method of claim 17 , further comprising:

receiving, by a data center, fifth data from the fourth level manager;

determining, by the data center, a fifth instruction based on the fifth data and user preferences; and

transmitting, by the data center, the fifth instruction to the vehicle,

wherein the fifth data includes link-level traffic information.
