Abstract

A method for intelligently managing a transportation network is provided. The method may include providing a roadside apparatus 18 to communicate with nodes 14A to 14D associated with vehicles 12A to 12D in a transportation network, the vehicle nodes being in a neighborhood range of the roadside apparatus. The roadside apparatus may dynamically detect the presence of a node 14A associated with a first vehicle 12A, and establish a mobile Internet Protocol (IP) network between the roadside apparatus and the first vehicle'"'"'s node. The roadside apparatus 18 receives, in real-time, from the first vehicle'"'"'s node 14A event data of events associated with the first vehicle 12A over the mobile IP network. The roadside apparatus 18 or nodes 14A to 14D may further receive or transmit real-time command data to control subsystems of a vehicle.

Claims

1. A method comprising:

establishing a mobile Internet Protocol (IP) network between a base station and a plurality of vehicles within a transportation network;

dynamically detecting the presence of a first node associated with a first vehicle utilizing the base station, and extending the mobile IP network to include the first node;

receiving over the mobile IP network real-time event data of events associated with the plurality of vehicles; and

processing the event data to assess whether a field of view of the first vehicle is obscured by another vehicle.

2. The method of claim 1, further comprising, in response to determining that the field of view of the first vehicle is obscured, assigning a high priority for transmitting real-time command data to the first vehicle.

3. The method of claim 2, further comprising processing the event data to assess whether the field of view of any of the plurality of vehicles is obscured by another vehicle, and assigning a higher priority to transmitting the real-time command data to each node associated with a vehicle having an obscured field of view.

4. The method of claim 1, wherein assessing whether the field of view of the first vehicle is obscured by another vehicle includes referencing dimension data relating to physical properties of the vehicles associated with the respective vehicle nodes.

5. The method of claim 4, wherein the dimension data includes at least one of a vehicle type, a physical size of the vehicle, and a shape of the vehicle.

6. The method of claim 1, comprising:

dynamically detecting the presence of a second node associated with a second vehicle;

extending the mobile Internet Protocol (IP) network to the second node;

receiving from the second node, over the mobile IP network in real-time, event data associated with the second vehicle; and

transmitting, over the mobile IP network in real-time, to any vehicle node forming part of the mobile IP network the event data received from the first node and from the second node.

7. The method of claim 6, in which the mobile IP network communication is via real-time IP audio and video wireless services technologies having a mission critical nature.

8. The method of claim 1, in which the event data comprises the geographic location of the vehicle, the velocity of the vehicle, the acceleration of the vehicle, the momentum of the vehicle, type of vehicle, dimension data of the vehicle, radar data, video data or laser range distance data relating to any nearby vehicle node forming part of the mobile IP network, or the weight of the vehicle.

9. The method of claim 1, farther comprising controlling vehicle subsystems associated with a particular one of the vehicles, in response to the event data received from the vehicle nodes, thereby to control the motion of the particular vehicle.

10. The method of claim 9, wherein the vehicle subsystems are controlled by transmitting real-time command data over the mobile IP network to the vehicle subsystems of any vehicle node forming part of the mobile IP network.

11. The method of claim 9, in which the vehicle subsystems comprise one or more of a throttle subsystem, a steering subsystem or a brake subsystem.

12. The method of claim 1, further comprising:

establishing a neighborhood of vehicle nodes associated with the first node;

and

facilitating posting of messages between vehicle nodes in the established neighborhood.

13. The method of claim 1, in which the base station is a roadside apparatus, the vehicle nodes being in neighborhood range of the roadside apparatus.

14. A system comprising:

a plurality of wireless nodes associated with respective vehicles in a transportation network, each wireless node comprising;

a mobility module to generate event data relating to events associated with the vehicle; and

a communication module to wirelessly communicate the event data in real-time over a mobile Internet Protocol (IP) network which includes other vehicle nodes in a neighborhood range of the node, and

a processing module to process the event data to assess whether a field of view of any vehicle is obscured by another vehicle.

15. The system of claim 14, further comprising a control module to transmit real-time command data over the mobile IP network to any vehicle node forming part of the mobile IP network, to control vehicle subsystems of the vehicle and thereby to control the motion of the vehicle.

16. The system of claim 15, wherein the processing module is to assign a high priority for transmitting real-time command data to a particular vehicle in response to an assessment by the processing module that the field of view of the particular vehicle is obscured by another vehicle.

17. The system of claim 14, wherein the processing module is to reference dimension data relating to physical properties of the vehicles associated with the respective vehicle nodes, to assess whether the field of view of any vehicle is obscured by another vehicle.

18. The system of claim 17, wherein the dimension data includes at least one of a vehicle type, a physical size of the vehicle, and a shape of the vehicle.

19. The system of claim 14, further comprising at least one roadside apparatus comprising a communication module to dynamically detect the presence of any node associated with a vehicle, and to extend the mobile IP network to the detected node, the at least one roadside apparatus forming part of the mobile IP network.

21. The system of claim 19, in which the event data comprises the geographic location of a vehicle, the velocity of the vehicle, the acceleration of the vehicle, the momentum of the vehicle, type of vehicle, dimension data of the vehicle, radar data, video data or laser range distance data relating to any nearby vehicle node forming part of the mobile IP network, or the weight of the vehicle.

22. The system of claim 19, in which the mobile IP network communication is via real-time IP audio and video wireless services technologies having a mission critical nature.

23. A system comprising:
