Abstract

Systems and methods are provided for estimating time travel distributions on signalized arterials. The systems and methods may be implemented as or through a network service. Traffic data regarding a plurality of travel times on a signalized arterial may be received. A present distribution of the travel times on the signalized arterial may be determined. A prior distribution based on one or more travel time observations may also be determined. The present distribution may be calibrated based on the prior distribution.

Claims

1. A system for estimating time travel distributions on signalized arterials, comprising:

a processor;

memory; and

an application stored in memory and executable by the processor to;

receive travel data,

estimate a distribution based on the travel data, and

calibrate the distribution.

2. The system of claim 1, wherein the travel data is received from one or more mobile GPS devices.

3. The system of claim 1, wherein the travel data is received from one or more reidentification devices.

4. The system of claim 3, wherein the reidentification device is a magnetic signature.

5. The system of claim 3, wherein the reidentification device is a toll tag.

6. The system of claim 3, wherein the reidentification device is a license plate.

7. The system of claim 3, wherein the reidentification device is a Bluetooth receiver.

8. The system of claim 1, wherein the travel data is received from a third-party server that collected the data.

9. The system of claim 1, wherein the server is an open-source server.

10. The system of claim 9, wherein the open-source server is operated by Sensys Networks, Inc. of Berkeley, Calif.

11. A method for estimating time travel distributions on signalized arterials, comprising:

receiving travel data; and

executing instructions stored in memory, wherein execution of the instructions by a computer processor;

estimates a distribution based on the travel data, and

calibrates the distribution.

12. The method of claim 11, wherein the travel data is received from one or more mobile GPS devices.

13. The method of claim 11, wherein the travel data is received from one or more reidentification devices.

14. The method of claim 13, wherein the reidentification device is a magnetic signature.

15. The method of claim 13, wherein the reidentification device is a toll tag.

16. The method of claim 13, wherein the reidentification device is a license plate.

17. The method of claim 13, wherein the reidentification device is a Bluetooth receiver.

18. The method of claim 11, wherein the travel data is received from a third-party server that collected the data.

19. The method of claim 11, wherein execution of the instructions by the computer processor further estimates traffic conditions on a particular signalized arterial segment based on the calibrated distribution.

20. The method of claim 11, wherein execution of the instructions by the computer processor further displays the estimated traffic conditions to a user through a graphical interface of a mobile device.
