Automated highway system (AHS)
A system and method for controlling vehicles and for providing assistance to operated vehicles is discussed and described herein.
1. A system, comprising:
a plurality of roadside units;
a plurality of proximity servers, each coupled to one or more of the roadside units and having a domain associated with the one or more of the coupled roadside units, each proximity server configured to track a progress of an active vehicle in the domain and to transmit vehicle movement control data to the active vehicle;
an automated highway control system coupled to the proximity server and configured to communicate with each of the roadside units via the proximity server and to modify the vehicle movement control data in response to traffic signal data; and
a database coupled to the proximity server and configured to receive and store data from each of the roadside units.
2. The system of claim 1 further comprising a plurality of active vehicles configured to interactively communicate with the plurality of roadside units, each of the active vehicles further comprising a control system configured to receive control data from each of the roadside units when it is in the domain containing the roadside units and to adjust one or more operational variable in response to the control data.
3. The system of claim 1 wherein a control system of each vehicle is configured to provide response data to the roadside units in response to the control data.
4. The system of claim 1 wherein at least one roadside unit is disposed at an on ramp of a controlled highway.
5. The system of claim 1 wherein at least one roadside unit is disposed at an off ramp of a controlled highway.
6. The system of claim 1 wherein at least one roadside unit is disposed at a lane marker of a controlled highway.
7. The system of claim 1 wherein at least one roadside unit is disposed at a high occupancy vehicle marker of a controlled highway.
8. The system of claim 1 wherein at least one roadside unit is disposed at a stop marker of a controlled intersection and is associated with the stop marker.
9. The system of claim 1 wherein at least one roadside unit is disposed at a lane use marker of a controlled intersection.
10. The system of claim 1 wherein at least one roadside unit is disposed at a cross walk marker of a controlled intersection and the vehicle movement control data is generated in response to traffic signal data that is transmitted to the proximity server.
11. A method, comprising:
providing a plurality of roadside units;
providing a proximity server coupled to each of the roadside units;
providing an automated highway control system coupled to the proximity server and configured to communicate with each of the roadside units via the proximity server;
the automated highway control system configured to communicate at least one traffic control signal associated with giving priority to an emergency vehicle; and
providing a database coupled to the proximity server and configured to receive and store data from each of the roadside units.
12. The method of claim 11 further comprising providing a control system to each of a plurality of vehicles, wherein the control system of each vehicle is configured to receive control data from each of the roadside units and traffic light status data from the at least one traffic control and to adjust one or more operational variable in response to the control data.
13. The method of claim 11 further comprising configuring a control system of each vehicle to provide response data to the roadside units in response to the control data and traffic light status data.
14. The method of claim 11 further comprising disposing at least one roadside at an on ramp of a controlled highway.
15. The method of claim 11 further comprising disposing at least one roadside unit at an off ramp of a controlled highway.
16. The method of claim 11 further comprising disposing at least one roadside unit at a lane marker of a controlled highway.
17. The method of claim 11 further comprising disposing at least one roadside unit at a high occupancy vehicle marker of a controlled highway.
18. The method of claim 11 further comprising disposing at least one roadside unit at a stop marker of a controlled intersection, wherein the roadside unit at the stop marker is in data communication with at least one traffic light.
19. The method of claim 11 further comprising disposing at least one roadside unit at a lane use marker of a controlled intersection, wherein the roadside unit at the lane control marker is in data communication with at least one traffic light.
20. The method of claim 11 further comprising disposing at least one roadside unit at a cross walk marker of a controlled intersection, wherein the roadside unit at the cross walk is in data communication with at least one traffic light.
