Abstract

A traffic adjustment or a traffic command, for example, is based on data congestion on a cellular network. Position data is received from a mobile device. A portion of a cellular network that corresponds to the position data is selected. The portion of the cellular network may be the geographic area covered by a cell. The network state of the portion of the cellular network is identified. A traffic device is also identified. The traffic device may be a traffic light or a variable speed sign. The traffic adjustment or traffic command for the traffic device is calculated based on the network state.

First claim

We claim:

1. A method of traffic control for at least one road via a traffic device, the method comprising:
detecting, by a processor of a traffic system, a presence of a mobile device at a location on the at least one road, wherein the mobile device is connected to a mobile network;
associating, by the processor, the mobile device with a portion of the mobile network corresponding to the location of the mobile device on the at least one road;
determining, by the processor, a congestion or usage level of the corresponding portion of the mobile network associated with the mobile device; and
controlling, by the processor, the traffic device at the location on the at least one road based on the determined congestion or usage level, wherein the mobile device is routed through the location on the at least one road via the traffic device.

2. The method of claim 1 , wherein the traffic device includes a traffic signal or a sign.

3. The method of claim 2 , wherein the traffic signal increases or decreases a wait time as a function of the determined congestion or usage level of the corresponding portion of the mobile network.

4. The method of claim 2 , wherein the traffic signal introduces a delay for a highway ramp based on the determined congestion or usage level of the corresponding portion of the mobile network.

5. The method of claim 1 , wherein the determined congestion or usage level is determined based on a measurement of transmission resources of the mobile network or utilization of the mobile network.

6. The method of claim 5 , wherein the transmission resources include bandwidth, signal strength, speed, or combinations thereof.

7. The method of claim 5 , wherein the utilization of the mobile network is based on a number of mobile devices connected to the mobile network or a type of data user of the mobile network, the mobile device being classified as a heavy data user or a light data user according to data usage of the mobile device.

8. An apparatus for traffic control for at least one road via a traffic device, the apparatus comprising:
a communication interface configured to detect a presence of a mobile device at a location on at least one road, wherein the mobile device is connected to a mobile network; and
a controller configured to:
associate the mobile device with a portion of a mobile network corresponding to the location of the mobile device on the at least one road;
determine a congestion or usage level of the corresponding portion of the mobile network associated with the mobile device, and
control the traffic device at the location on the at least one road based on the determined congestion or usage level, wherein the mobile device is routed through the location on the at least one road via the traffic device.

9. The apparatus of claim 8 , wherein the traffic device displays a speed limit as a function of the determined congestion or usage level of the corresponding portion of the mobile network.

10. The apparatus of claim 8 , wherein the traffic device displays a message based on the determined congestion or usage level of the corresponding portion of the mobile network.

11. The apparatus of claim 8 , wherein the determined congestion or usage level is based on a number of mobile devices connected to the mobile network, historic usage patterns of mobile devices, or combinations thereof.

12. The apparatus of claim 11 , wherein the historic usage patterns are based on time of day, day of week, or an event.

13. A method of controlling flow of road traffic in and out of one or more cells within a mobile network connected to a mobile device, the method comprising:
detecting, by a processor of a traffic system, a presence of the mobile device associated with a vehicle at a location on a road;
identifying, by the processor, the one or more cells of the mobile network corresponding to the location of the mobile device;
determining, by the processor, a congestion or usage level for the one or more cells of the mobile network; and
routing, by the processor, the vehicle through the one or more cells of the mobile network based on the determined congestion or usage level, wherein routing the vehicle comprises providing, by the processor, a traffic command to the mobile device associated with the vehicle, wherein the mobile device generates a driving command in response to receiving the traffic command to control an operation of the vehicle.

14. The method of claim 13 , wherein said routing the vehicle includes increasing a rate of movement of the vehicle from a cell having a high congestion or usage level to a cell having a low congestion or usage level, decreasing a rate of movement of the vehicle from a cell having a low congestion or usage level to a cell having a high congestion or usage level, or combinations thereof.

15. The method of claim 13 , wherein the driving command engages a mechanical system of the vehicle.

16. A non-transitory computer readable medium including instructions that when executed by a processor are operable to:
detect a presence of a mobile device associated with a vehicle at a location on at least one road, wherein the mobile device is connected to a mobile network;
associate the mobile device with a portion of the mobile network corresponding to the location of the mobile device on the at least one road;
determine a congestion or usage level of the corresponding portion of the mobile network associated with the mobile device; and
route the vehicle through the location on the at least one road based on the determined congestion or usage level, wherein routing the mobile device comprises:
controlling, by the processor, a traffic device at the location on the at least one road based on the determined congestion or usage level and routing the vehicle through the location on the at least one road via the traffic device; or
providing, by the processor, a traffic command to the mobile device associated with the vehicle, wherein the mobile device generates a driving command in response to receiving the traffic command to control an operation of the vehicle.

17. The non-transitory computer readable medium of claim 16 , wherein the driving command engages a mechanical system of the vehicle.
