What is Portal?


The Portal Story

Welcome to Portal, the official transportation archive for the Portland-Vancouver metropolitan region. The purpose of this project is to implement the U.S. National ITS Architecture's Archived Data User Service for the Portland-Vancouver metropolitan region. This system is being developed at Portland State University by students and faculty in the Intelligent Transportation Systems Laboratory under the direction of Dr. Kristin Tufte. We are working in close cooperation with the Oregon Department of Transportation, Metro, the City of Portland, TriMet, the Southwest Washington Regional Transportation Council and other regional partners. This work is supported by grants distributed through Metro and by the Southwest Washingtion Regional Transportation Council , the Oregon Transportation, Research and Education Consortium, the National Science Foundation , and the Federal Highway Administration.

We welcome your participation in our project. The current PORTAL system archives a wide variety of transportation-related data including the freeway loop detector data from the Portland-Vancouver metropolitan region, weather data, incident data, transit data and freight data. We plan to expand the capabilities of our system and to include multimodal data sources, including additional transit data, arterial data and bicycle-pedestrian data from both Oregon and Washington. Please explore the site and let us know what you think. Feedback can be submitted on the Support tab.

PORTAL was founded by Dr. Robert L. Bertini. Dr. Bertini is currently on leave and is serving as the Deputy Administrator of the Research and Innovative Technology Administration [RITA] at the U.S. Department of Transportation.

Spicer Matthews ,

Staff Researcher
B.S.

B.S., Computer Science, Portland State University,

Spicer would like to think of himself as an international man of mystery, a connoisseur of life, a sage of perfection, or even a conqueror of intellect. However, none of these things are true. Spicer is actually a staff researcher on the PORTAL project and is currently working on prototype Web 2.0 features for PORTAL. Along with working on PORTAL, Spicer is also a property manager and IT consultant. Yes, a rather odd combo, you will have to corner Spicer to find out more about this broad career that he has. When he is not working, Spicer loves snowboarding, mountain biking, and white water kayaking.

PORTAL data was used to prepare corridor operating condition summaries to be included in the regional Transportation Systems Management and Operations (TSMO) plan. These summaries are an example of the use of PORTAL data for planning and problem identification. We include links to two example summaries one for I-5 NB and one for I-5 SB. The summaries were created by Jen Bachman of DKS. Thanks to Jim Peters, also of DKS, for providing them to the ITS Lab team.


PORTAL TAC Kickoff Meeting - January 2009

Rafael Fernandez presents paper at CIDR 2009 - January 2009

Rafael J. Fernandez-Moctezuma, Kristin Tufte, and Jin Li authored the paper "Inter-Operator Feedback in Data Stream Management Systems via Punctuation", accepted to the Fourth Biennial Conference on Innovative Database Research (CIDR 2009). The conference had a 27% accept rate. The paper documents a new inter-operator feedback mechanism in stream engines. The work is part of the latte project, which aims toward refinement and development of stream engines which support online processing of data streams, such as the traffic data from freeway loop detectors.

PORTAL October Report Produced - November 2008

The PORTAL October report has been produced. This report details a high-level investigation into the data quality of the ODOT loop detector data in the PORTAL data archive addressing issues such as validity of no traffic readings, technically invalid zero occupancy readings, high speed readings and low overnight speeds. Conclusions and recommendations are included. Report
