The Oregon Department of Transportation (ODOT) currently operates a comprehensive Advanced Traffic Management System (ATMS). ATMS collects data from various sources and archives it for later usage. In this paper we demonstrate several techniques for measuring and assessing the performance of Portland, Oregon’s existing PRM system. These techniques can help departments of transportation (DOTs) in locations where PRM has been applied to measure the performance of their systems. This type of analysis uses data that are already being collected as part of an overall Intelligent Transportation System (ITS) deployment.

USING ARCHIVED ITS DATA TO MEASURE THE OPERATIONAL BENEFITS OF A SYSTEM-WIDE ADAPTIVE RAMP METERING SYSTEM Final Report USING ARCHIVED ITS DATA TO MEASURE THE OPERATIONAL BENEFITS OF A SYSTEM-WIDE ADAPTIVE RAMP METERING SYSTEM
A System-Wide Adaptive Ramp Metering (SWARM) system has been implemented in the Portland, Oregon metropolitan area, replacing the previous pre-timed ramp-metering system that had been in operation since 1981. SWARM has been deployed on six major corridors and operates during the morning and afternoon peak hours. This report presents results of a " before " and " after " evaluation of the perfor...

The Area under the ROC Curve (AUC) is a common index for evaluating the ability of the biomarkers for classification. In practice, a single biomarker has limited classification ability, so to improve the classification performance, we are interested in combining biomarkers linearly and nonlinearly. In this study, while introducing various types of loss functions, the Ramp AUC method and some of...
