Abstract

An infrastructure state prediction device includes a processor configured to receive sensor information from a sensor at an infrastructure element, wherein the sensor information includes an observation of a traffic object at the infrastructure element; and determine, based on the sensor information and an infrastructure state model comprising information indicative of a state timing for the infrastructure element, an updated state timing for the infrastructure element; and a transmitter configured to transmit the updated state timing to the infrastructure element.

First claim

What is claimed is:

1. A non-transitory computer readable medium for determining and communicating a modified route for a vehicle based on sensor information corresponding to a portion of a planned route of the vehicle and sensor information corresponding to a portion outside of the planned route of the vehicle, comprising instructions which, when executed, cause one or more processors to:
receive vehicle information indicating the planned route of the vehicle;
receive first sensor information from a first sensor at a first infrastructure element,
wherein the sensor information represents a first traffic status at the first infrastructure element, wherein the first infrastructure element is along the planned route;
receive second sensor information from a second sensor at a second infrastructure element, wherein the second sensor information represents a second traffic status at the second infrastructure element, wherein the second infrastructure element is not along the planned route;
determine the modified route for the vehicle based on the first traffic status and the second traffic status, wherein the second infrastructure element is along the modified route;
generate a message comprising the modified route; and
control a transmitter to send the message to the vehicle.

2. The non-transitory computer readable medium of claim 1 , wherein the first traffic status comprises information about at least one of a stopped traffic, a moving traffic, a traffic quality, a traffic quantity, and/or a traffic disruption.

3. The non-transitory computer readable medium of claim 1 , wherein the instructions are further configured to cause the one or more processors to receive an infrastructure state model comprising information indicative of state timings for the first and second infrastructure elements, wherein the modified route is further based on the infrastructure state model.

4. The non-transitory computer readable medium of claim 3 , wherein the instructions are further configured to cause the processor to update, as an updated infrastructure state model, the infrastructure state model based on the first traffic status and/or the second traffic status, and to control the transmitter to send the updated infrastructure state model.

5. A non-transitory computer readable medium for determining and sending movement information to a vehicle to evade an object in a planned route of the vehicle based on sensor information from an infrastructure element, comprising instructions which, when executed, cause one or more processors to:
receive a prediction request from the vehicle, wherein the prediction request is associated with an infrastructure element along the planned route of the vehicle;
receive sensor information from a sensor at the infrastructure element, wherein the sensor information comprises information about the object at the infrastructure element;
determine, based on the sensor information and the planned route, that the object impacts the planned route of the vehicle;
determine, based on the sensor information and the planned route, movement information for the vehicle;
generate a message comprising the movement information; and
control a transmitter to send the message to the vehicle.

6. The non-transitory computer readable medium of claim 5 , wherein the movement information comprises at least one of a vehicle velocity instruction, a vehicle acceleration instruction, a vehicle timing instruction, or a route instruction for the vehicle to avoid the object.

7. The non-transitory computer readable medium of claim 5 , wherein the object comprises at least one of another vehicle and/or a pedestrian.

8. The non-transitory computer readable medium of claim 5 , wherein the prediction request comprises a request for information about a traffic status at the infrastructure element.

9. An infrastructure state modelling system for updating an infrastructure state model comprising timings for a plurality of infrastructure elements based on a state timing and traffic information, comprising:
a server configured to store the infrastructure state model for an infrastructure element;
a sensor configured to observe traffic status information at the infrastructure element;
a control unit for the infrastructure element, the control unit in communication with the infrastructure element, the sensor, and the server and configured to:
receive the infrastructure state model and the traffic status information;
determine the state timing for the infrastructure element based on the infrastructure state model and the traffic status information; and
transmit the state timing and the traffic status information to the server, wherein the server is configured to update the infrastructure state model based on the state timing and the traffic information;
wherein the infrastructure state model comprises state timings for the plurality of infrastructure elements.

10. The infrastructure state modelling system of claim 9 , wherein traffic status information comprises traffic status information for the plurality of infrastructure elements.

11. The infrastructure state modelling system of claim 10 , wherein the traffic status information for each of the plurality of infrastructure elements comprises an observed traffic status at each infrastructure element.

12. A non-transitory computer readable medium for determining a state timing and a traffic status information for updating an infrastructure state model, comprising instructions which, when executed, cause one or more processors to:
store the infrastructure state model for an infrastructure element;
observe traffic status information at the infrastructure element;
receive the infrastructure state model and the traffic status information;
determine a state timing for the infrastructure element based on the infrastructure state model and the traffic status information; and
control a transmitter to send the state timing and the traffic status information to a server.

13. The non-transitory computer readable medium of claim 12 , wherein the infrastructure state model comprises state timings for a plurality of infrastructure elements.
