Abstract

A management system for a traffic lane achieves congestion management objectives by dynamically predicting future vehicle density in a traffic lane and assigning to a requesting user a time slot for entering the traffic lane selected independent of any user requested time and based at least in part on a current prediction about future vehicle density in the traffic lane. The current prediction is based at least in part on predicted trajectories of vehicles, which are determined in turn based at least in part on actual trajectories of vehicles.

Claims

1. A management system for a traffic lane, comprising:

a user interface; and

a control system communicatively coupled with the user interface, wherein the control system dynamically predicts future vehicle density in the traffic lane and in response to a request input by a user on the user interface offers to the user via the user interface a time slot for a vehicle to enter the traffic lane selected by the control system independent of any time requested by the user and based at least in port on a current prediction of future vehicle density in the traffic lane.

2. The management system of claim 1, wherein the time slot is the first available time slot.

3. The management system of claim 1, further comprising a detection system communicatively coupled with the control system, wherein the control system dynamically predicts future vehicle density based at least in part on information collected by the detection system.

4. The management system of claim 1, wherein the information collected by the detection system comprises at least one of radio navigation satellite system (RNSS) information, contactless identification system information, inductive-loop system information, vision-based system information or radar-based system information.

5. The management system of claim 1, wherein the control system dynamically predicts future vehicle density based at least in part on predicted trajectories of vehicles.

6. The management system of claim 1, wherein the control system determines the predicted trajectories based at least in part on measured trajectories of vehicles.

7. The management system of claim 1, wherein the request comprises an identification of the user.

8. The management system of claim 1, wherein the request comprises an identification of the vehicle.

9. The management system of claim 1, wherein the request comprises an identification of an entry point and an exit point from the traffic lane.

10. The management system of claim 1, wherein the request comprises an identification of a trip origination point and destination point from which the control system identifies an entry point and an exit point from the traffic lane.

11. The management system of claim 1, wherein the control system compares the current prediction of future vehicle density with a predetermined vehicle density threshold and offers the time slot in response to a determination that the predicted vehicle density does not exceed the predetermined vehicle density threshold.

12. The management system of claim 1, wherein the control system compares the current prediction of future vehicle density with a predetermined paid vehicle density threshold that is higher than a predetermined unpaid vehicle threshold and offers the time slot for a fee in response to a determination that the predicted vehicle density does not exceed the predetermined paid vehicle density threshold.

13. The management system of claim 1, wherein the user inputs on the user interface an acceptance of the time slot.

14. The management system of claim 13, wherein the control system imposes a fee upon the user if after the acceptance the vehicle fails to enter the traffic lane during the time slot.

15. The management system of claim 1, wherein the control system deems the time slot rejected if the user foils within a predetermined time less than fifteen seconds after the offer to input on the user interface an acceptance of the time slot.

16. The management system of claim 1, wherein the time slot is selected further based at least in part on a location of the vehicle.

17. The management system of claim 1, wherein the user interface is integral to one of a telephone, a personal computer or the vehicle.

18. A method for management of a traffic lane, comprising the steps of:

dynamically predicting future vehicle density in the traffic lane;

assigning in response to a request made by a user a time slot for a vehicle to enter the traffic lane selected independent of any time requested by the user and based at least in part on a current prediction of future vehicle density in the traffic lane; and

offering the time slot to the user.

19. The method of claim 18, wherein the future vehicle density in the traffic lane is dynamically predicted based at least in port on predicted trajectories of vehicles.

20. The method of claim 19, wherein the predicted trajectories of vehicles are determined based at least in part on measured trajectories of vehicles.
