Abstract:

The overall goal of this project is to integrate and operationalize weather-sensitive TrEPS models calibrated for

the Salt Lake City region to support weather-responsive traffic signal timing implementation and evaluation in

the Riverdale corridor in Ogden, UT. The TrEPS model selected for this study is DYNASMART-X, a real-time

system that interacts continuously with loop detectors, roadside sensors and vehicle probes, providing real-time estimates of traffic conditions, network flow patterns and routing information. The results confirm the

ability of the calibrated TrEPS to replicate observed traffic patterns in a large corridor network. With the current

detectors and roadside sensors coverage, DYNASMART-X is able to use available real-time measurements to

improve the quality of its estimation and future prediction, and thus provide a reliable basis for improved traffic

management decisions that anticipate future conditions. This study successfully demonstrates a working

TrEPS system installed at the UDOT Traffic Management Center and leverages the existing traffic detection

installation to extract real-time traffic state variables as a real-time input to the system.
