Abstract

A toll system for a set of road portions where tolls are set on a per vehicle and per journey basis. Each time a given vehicle plans to take a journey the tolls are computed for that vehicle and for that journey, and the amount of the tolls are set based, at least in part, on the characteristics of the vehicle and/or the planned journey. This can incentivize more socially desirable traffic flows.

Claims

1. A method comprising:

collecting demand information representing estimated usage of a plurality of roads by a plurality of vehicles, with each road including at least one road portion; and

determining a plurality of sets of tolls with each set of tolls;

(i) respectively corresponding to a specific respective vehicle of the plurality of vehicles, (ii) including tolls for each road portion of the plurality of roads, and (iii) being based, at least in part, upon the estimated usage;

wherein;

at least the determination of a plurality of sets of tolls is performed by a machine using machine logic.

2. The method of claim 1 wherein the determination of the plurality of sets of tolls further determines the sets of tolls so that each set of tolls corresponds respectively to a specific planned journey from an origin location to a destination location by a specific vehicle.

3. The method of claim 1 further comprising:

determining a desired traffic flow pattern by the plurality of vehicles over the road portions;

wherein;

the determination of the plurality of sets of tolls is made to incentivize the plurality of vehicles to follow an actual traffic flow pattern that is closer to the desired traffic flow pattern than a natural traffic flow pattern; and

the natural traffic flow pattern is a traffic flow pattern which the vehicles would follow absent any tolls.

4. The method of claim 3 wherein determination of the desired traffic pattern includes:

estimating vehicle demand; and

applying a first network performance function using a network model.

5. The method of claim 3 wherein the determination of the plurality of sets of tolls is made based, at least in part, on consideration of at least one of the following additional objectives:

(i) decreasing a total amount of tolls charged collectively to the plurality of vehicles, (ii) decreasing a maximum toll charged to a vehicle, (iii) decreasing a maximum toll charged to a vehicle at a specific location, (iv) decreasing price heterogeneity between vehicles, and/or (v) decreasing a discrepancy between a predetermined desired total toll amount and a total toll amount.

6. The method of claim 1 wherein the tolls of each set of tolls is based, at least in part, on the identity of the vehicle to which the set of tolls applies and at least one of the following additional factors:

(i) the vehicle'"'"'s origin location, (ii) the vehicle'"'"'s destination location, (iii) a time of day;

(iv) a day of week, and/or (v) a desired traffic level.

7. The method of claim 1 wherein the determination of the plurality of sets of tolls is determined under at least a first operational constraint.

8. The method of claim 7 wherein the first operational constraint is one of the following:

(i) a predetermined, fixed toll for at least one road portion, or (ii) a fairness constraint.

9. The method of claim 1 wherein the determination of the plurality of sets of tolls is based, in part, on at least one of the following factors:

(i) emissions of the vehicle corresponding to a set of tolls, (ii) noise level of the vehicle corresponding to a set of tolls, and/or (iii) fuel consumption of the vehicle corresponding to a set of tolls.

10. The method of claim 1 wherein the determination of the plurality of sets of tolls is based, in part, on at least one of the following factors:

(i) a driving style of the vehicle corresponding to a set of tolls, and (ii) circuitous driving prior to parking of the vehicle corresponding to a set of tolls.

11. The method of claim 1 wherein the determination of the plurality of sets of tolls is based, at least in part, on trajectory information respectively associated with the vehicles of the plurality of vehicles.

12. The method of claim 11 further comprising:

determining trajectory information for at least some of the vehicles of the plurality of vehicles using at least one of the following;

(i) data from geo-positioning devices, and/or (ii) data from fixed re-identification detectors.

13. The method of claim 1 further comprising:

determination of routes taken by each vehicle of the plurality of vehicles over the road portions of the plurality of road portions; and

charging tolls to the vehicles based upon the sets of tolls.

14. The method of claim 13 wherein the determination of routes is based upon at least one of the following factors:

(i) data received from global positioning devices in or on the vehicles of the plurality of vehicles, and/or (ii) a driving time for a vehicle

15. The method of claim 13 wherein the determination of the plurality of sets of tolls ensure that geographically proximate routes that have similar expected associated travel times will have at least approximately the same toll.

16. A computer program product comprising software stored on a software storage device, the software comprising:

first program instructions programmed to collect demand information representing estimated usage of a plurality of roads by a plurality of vehicles, with each road including at least one road portion; and

second program instructions programmed to determine a plurality of sets of tolls with each set of tolls;

(i) respectively corresponding to a specific respective vehicle of the plurality of vehicles, (ii) including tolls for each road portion of the plurality of roads, and (iii) being based, at least in part, upon the estimated usage;

wherein;

the software is stored on a software storage device in a manner less transitory than a signal in transit.

17. The product of claim 16 wherein the second program instructions are further programmed to determine the sets of tolls so that each set of tolls corresponds respectively to a specific planned journey from an origin location to a destination location by a specific vehicle.

18. The product of claim 16 wherein the software further comprises:

third program instructions programmed to determine a desired traffic flow pattern by the plurality of vehicles over the road portions;

wherein;

the second program instructions are further programmed to determine the plurality of sets of tolls to incentivize the plurality of vehicles to follow an actual traffic flow pattern that is closer to the desired traffic flow pattern than a natural traffic flow pattern; and

the natural traffic flow pattern is a traffic flow pattern which the vehicles would follow absent any tolls.

19. A computer system comprising:

a processor(s) set; and

a software storage device;

wherein;

the processor set is structured, located, connected and/or programmed to run software stored on the software storage device; and

the software comprises;

first program instructions programmed to collect demand information representing estimated usage of a plurality of roads by a plurality of vehicles, with each road including at least one road portion; and

second program instructions programmed to determine a plurality of sets of tolls with each set of tolls;

(i) respectively corresponding to a specific respective vehicle of the plurality of vehicles, (ii) including tolls for each road portion of the plurality of roads, and (iii) being based, at least in part, upon the estimated usage.

20. The system of claim 19 wherein second program instructions are further programmed to determine the sets of tolls so that each set of tolls corresponds respectively to a specific planned journey from an origin location to a destination location by a specific vehicle.
