predict a future traffic state at the estimated future time;

determine the driving instructions for the vehicle based on the predicted future traffic state; and

transmit the driving instructions to the vehicle to cause the vehicle to perform autonomous driving to implement the driving instructions.

14. The server of claim 13 , wherein the controller is further configured to:

estimate a first latency in transmission from the vehicle to the server;

estimate a second latency in transmission from the server to the vehicle; and

estimate the future time at which the vehicle will receive the driving instructions transmitted by the server based on the first latency and the second latency.

15. The server of claim 13 , wherein the controller is further configured to:

receive a timestamp indicating a first time that the data was transmitted from the vehicle; and

estimate the future time based on the timestamp indicating the first time and a second time at which the server receives the data from the vehicle.

16. The server of claim 15 , wherein the controller is further configured to:

estimate a latency in transmission from the vehicle to the server based on a difference between the first time and the second time.

17. The server of claim 15 , wherein the controller is further configured to:

estimate a latency in transmission from the server to the vehicle based on a difference between the first time and the second time.

18. A traffic management system comprising:

a plurality of sub systems; and

at least one main system being in a higher hierarchical level than the plurality of sub systems, wherein:

each of the plurality of sub systems is configured to:

receive data from one or more vehicles indicating a traffic state at a first time;

transmit the data received from the one or more vehicles to the main system;

receive, from the main system, driving instructions for at least one of the one or more vehicles; and

transmit the driving instructions for the at least one of the one or more vehicles to the at least one of the one or more vehicles; and

the at least one main system is configured to:

receive the data from the plurality of sub systems;

determine a traffic state at the first time based on the data received from the plurality of sub systems;

estimate a second time at which the at least one of the one or more vehicles will receive the driving instructions transmitted by one of the sub systems;

predict a traffic state at the second time based on the determined traffic state at the first time and the estimated second time;

determine the driving instructions for the at least one of the one or more vehicles to achieve a predetermined goal, based on the predicted traffic state at the second time; and

transmit the determined driving instructions to one or more of the sub systems to cause the vehicle to perform autonomous driving to implement the driving instructions.

19. The traffic management system of claim 18 , wherein the at least one main system is further configured to:

estimate a first latency in transmission from the one or more vehicles to the plurality of sub systems;

estimate a second latency in transmission from the plurality of sub systems to the main system;

estimate a third latency in transmission from the main system to the plurality of sub systems;
