Estimating time travel distributions on signalized arterials
View Patent ↗A system is provided for estimating time travel distributions on signalized arterials. The system may be implemented as 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.
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, about a signalized arterial collected by one or more reidentification devices, the travel data corresponding to data collected within a common time segment in each of a plurality of different days,
normalize the travel data into a plurality of individual pace values, the pace values expressed as a ratio of time per distance,
calculate an average pace value for the signalized arterial as a linear combination of the individual pace values weighted by distance traveled across the signalized arterial,
estimate a distribution based on the average pace value,
store the estimated distribution in memory,
receive real-time travel data about the signalized arterial collected by one or more reidentification devices,
calibrate the distribution based on the real-time travel data, and
generate a real-time prediction of the traffic conditions of the signalized arterial based on the calibrated 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.
