Abstract

A traffic management system (31) is described that combines wireless tracking of motorists (32) with scheduling of time slots for travel on roadways (33) during peak hours. Rewards are given to motorists (32) who travel during allotted time slots thus improving the effectiveness of the system over time. Motorists are tracked using their cellular device to check if a reward can be given or not, based on travel undertaken in the allotted time slot.

Claims

1. A roadway traffic management system comprising:

a time slot scheduling module; and

a motorist tracking module;

wherein said time slot scheduling module enables scheduling a travel time slot for said motorist in a desired roadway, and said motorist tracking module enables tracking of said motorist to check if said motorist is traveling in said roadway in said time slot.

2. The roadway traffic management system of claim 1, further comprising:

a motorist reward module wherein said motorist reward module rewards said motorist for traveling in said time slot.

3. The roadway traffic management system of claim 2, further comprising:

a motorist communication module that enables said motorist to communicate with said time slot scheduling module.

4. The roadway traffic management system of claim 3, wherein said communication module supports communication standards selected from group consisting of simple messaging service based communication standard, interactive voice response based standard, and internet data based communication standard.

5. The roadway traffic management system of claim 4, wherein said communication module enables bidirectional communication to send and receive time slot scheduling messages, and other broadcast informational messages.

6. The roadway traffic management system of claim 1, further comprising:

a traffic load calculation module to calculate traffic load at a given point in time of any desired roadway that implements said traffic management system, wherein input to said traffic load calculation module is derived from said motorist tracking module.

7. The roadway traffic management system of claim 1, further comprising:

a route calculation module to calculate travel routes in said time slots for said motorists based on data from said traffic load calculation module.

8. The roadway traffic management system of claim 1, wherein said motorist tracking module is implemented using tracking methods that track cellular devices in a cellular network.

9. The roadway traffic management system of claim 8, wherein said motorist tracking module is implemented using tracking methods that track cellular devices in a using cellular network standards selected from group consisting of global system for mobile standard based cellular network, code division multiple access standard based cellular network, and other cellular networks.

10. A method of managing roadway traffic comprising:

scheduling a motorist for a desired time slot to travel on said roadway with a time slot scheduling module; and

tracking said motorist traveling in said roadway in a motorist tracking module, to check if said motorist traveled in said scheduled time slot on said roadway.

11. The method of managing roadway traffic of claim 10, further comprising:

rewarding said motorist for traveling in said roadway in said scheduled time slot using a motorist reward module.

12. The method of managing roadway traffic of claim 11, further comprising:

communicating using a communication module from a device associated with said motorist to said scheduling module to initiate said scheduling of said time slot.

13. The method of managing roadway traffic of claim 12, wherein said communication module supports communication standards selected from group consisting of simple messaging service based communication standard, interactive voice response based standard, and internet data based communication standard.

14. The method of managing roadway traffic of claim 13, wherein said communication module enables bidirectional communication to send and receive scheduling messages, and other broadcast informational messages.

15. The method of managing roadway traffic of claim 10, further comprising:

calculating traffic load conditions in a traffic load calculation module, at a given point in time of any desired roadway that implements said roadway traffic management method, wherein input to said traffic load calculation module is derived from said motorist tracking module.

16. The method of managing roadway traffic of claim 10, further comprising:

calculating travel routes for said motorists in a route calculation module to calculate travel routes in said time slots for said motorists based on data from said traffic load calculation module.

17. The method of managing roadway traffic of claim 10, wherein said motorist tracking module is implemented using tracking methods that track cellular devices in a cellular network.

18. The method of managing roadway traffic of claim 17, wherein said motorist tracking module is implemented using tracking methods that track cellular devices in using cellular network standard selected from group consisting of global system for mobile standard based cellular network, code division multiple access standard based cellular network, and other cellular networks.
