OBJECTIVE
The objective of this project was to advance the work done in NCHRP Project 03-79 by developing additional techniques to measure traffic signal system performance and arterial travel time.
STATUS
The project is complete. The contractor's final deliverables are available through the links below.
Additional work on this topic has been done and published as Performance Measures for Traffic Signal Systems: An Outcome-Oriented Approach. Demonstration of the implementation of the techniques is available at https://udottraffic.utah.gov/signalperformancemetrics/
TASKS
Task 1. Develop and document techniques for measuring the performance of a single signalized intersection.
Task 2. Develop and document techniques for measuring the performance of an arterial.
Task 3. Apply the techniques developed in Tasks 1 and 2 at the Noblesville, Indiana test site.
Task 4. Develop procedures for making operational decisions using the performance measurement techniques developed in Tasks 1 and 2.
Task 5. Recommend detector configuration schemes for the performance measurement techniques developed in Tasks 1 and 2.
Task 6. Prepare a report describing how transportation agencies can apply the results of Task 1 through 5.
Task 7. Design an open architecture multimedia database for archiving vehicular signatures and photographs.
Task 8. Collect vehicular signature data and photographs for use in Tasks 9 and 10.
Task 9. Develop and refine an algorithm for determining arterial travel times using vehicular signatures.
Task 10. Develop a website for the Task 7 database and reports documenting the successes and failures of the Task 9 algorithm.
Task 11. Prepare a report describing how transportation agencies can apply the results of Tasks 7 through 10.
