A System-Wide Adaptive Ramp Metering (SWARM) system is being implemented in the Portland metropolitan area and should be operational on all corridors by April 2006. This study entails a before and after evaluation of the operational benefits of the new SWARM system using the existing data, surveillance and communications infrastructure. In particular, the study will quantify system-wide benefits in terms of savings in delay, emissions and fuel consumption and safety improvements on and off the freeway due to the implementation of the ramp metering system. This will aid in the optimal deployment of current SWARM system and will be transferable to other regions as their systems come on line in the future.

The Tri-County Metropolitan Transportation District of Oregon (TriMet), the transit provider for urban Clackamas, Multnomah, and Washington Counties, has been a leader in applying ITS technologies to its operations since the mid-1990s. The use of ITS technology has enhanced service for its customers while providing significant operational efficiencies.
In this presentation, analyst David Crout will describe many of TriMet's ITS projects, including the automatic vehicle location (AVL) system, computer-aided dispatch (CAD), real-time customer information, transit signal priority, and automatic stop announcements, and show how they have resulted in improved service and cost savings for the agency.
The 8th Annual Region X Student Conference was hosted by Oregon State University in Corvallis on Friday and 70 students attended. Conference organizer Jon Mueller said that a surprising number of students from the materials science and economics departments attended and that a significant number of undergraduates from OSU attended parts of the conference.
The conference featured a morning keynote presentation by Galen McGill, manager of the Intelligent Transportation Systems (ITS) unit for the Oregon DOT. The students learned about Oregon’s efforts to confront the challenge of scarce financial resources by applying technology to increase the productivity of existing infrastructure. Galen touched on recent advances in technologies such as OnStar and strategies such as Active Traffic Management, which has been adopted in Seattle and will soon be deployed in Oregon.
The late morning and early afternoon showcased student research. Eight students gave lecture-style presentations in the late morning and there was so much interest and so many questions that the session ran late and into the scheduled lunch hour. The presentations – four from PSU and four from OSU – revealed similar research interests between the campuses. The poster session in the afternoon provided a less structured forum in which the participants could interact.
The later afternoon offered students 3 workshops to attend. The group was divided into three subsets, each workshop was...Read more
OTREC students and faculty were active participants in the 15th World Congress on Intelligent Transportation Systems, held in New York City, November 16-20, 2008. Lisa Diercksen, an MS student at PSU presented “A Second Look at the Effectiveness of the Myrtle Creek Dynamic Advanced Curve Warning System;” Jerzy Wieczorek, an MS student in Statistics at PSU presented “Using Archived ITS Data to Automatically Identify Freeway Bottlenecks in Portland, Oregon;” Rafael J. Fernandez-Moctezuma, a Ph.D. student in computer science at PSU presented “Developing an Imputation Strategy for an Archived Data User Service in Portland, Oregon;” Galen McGill of the Oregon Department of Transportation presented “Accuracy in Real-Time Estimation of Travel Time,” co-authored with PSU Prof. Kristin Tufte. Prof. Robert Bertini of PSU also presented: “Empirical Evaluation of Adaptive Ramp Metering Along Two Freeway Corridors in Portland, Oregon;” and “Toward Transport Payment Integration in Portland, Oregon.” Prof. David Porter and Prof. David Kim, of the OSU Department of Industrial and Manufacturing Engineering also attended the Congress. The World Congress is sponsored by ITS AMerica, ERTICO-ITS Europe and ITS Japan.
