  1. Portal 2.0: Towards a Next-Generation Archived Data User Service Kristin Tufte, Robert L. Bertini, John Chee, Rafael J. Fernandez-Moctezuma, SathishPeriasamy, ShreemoyeeSarkar, Poonam Singh, James Whiteneck, Spicer Matthews, Nevin Freeman, SoyoungAhn Jan 12, 2010

  2. Introduction • PORTAL established 2004 • Simple web interface, single data source • Now - 2010 • 1 TB data; large web site • Data: freeway, transit, weather, incident, freight, traffic counts • Uses • Local transportation professionals • Regional Transportation Plan • Local news media • Research projects • Initial Goals Achieved

  3. Portal 2.0 Interface • Wide variety of users; different needs and interests • Glance at current traffic conditions • Analysis or understanding of a current event (traffic managers) • Trending and forecast information (planners) • In-depth analysis (researchers) • Design Principles • Intuitive, interactive, user-drivengraphical interface • Good set of defaults and intuitive interface • User-driven selections and advanced options and customization • Web 2.0 Interface • Adobe Flash, Google Maps • Effectively display results combining data fromdiverse sources • Functionality grouped by freeway system subset (system, highway, station)

  9. Stations Page –Main Map

  10. Stations Page - Detail

  11. Portal 2.0 Pages • Home: User-customizable landing page • Systems: Performance of they system as a whole • Highways: Tools for analyzing entire highways; will be updated to support user-selected corridors • Stations: Tools for analysis of an individual station (a particular freeway location) • Data Quality: Detectors producing suspicious data. • News & Info: News and information about the Portal 2.0 project and team members • Support: Documentation, publications, feedback, problem reports.

  12. Custom APIs - R • Easily integrate graphics from ITS Lab projects into Portal 2.0 • Many projects use Portal data • R - primary graphics tool for ITS Lab • Portal-R Framework • Researchers write graphical displays in R • Simple specification; no need to know web development • Displays semi-automatically integrated into Portal 2.0 • Capitalize on the great work done by ITS Lab researchers I-5 NB – Jul 09 – Jan 10 R program courtesy Alex Bigazzi

  13. Data Quality • Goal: Efficient use of maintenance resources • Prioritize detectors to be visited • Field Visits • Correlate anomalies observed in the data with issues in the field • Web site • Detectors producing suspicious data • Detectors not producing data • Detectors with data failing pre-set criteria (i.e. 20-sec vol > 17, speed > 100 mph, etc.) at a high rate • Offline detectors (construction, damage, etc.)

  14. Field Visits – Low Occupancy Blurry - need to update images…

  15. Data Quality Web Site

  16. Still thinking on this one… Going Forward… • Next Steps • Expansion to Vancouver, WA • Increased use of Transit Data • Sustainability/Green Metrics • Funding: TransPortMTIP (OR), RTC (WA), OTREC, NSF, FHWA • Goals/Mission • Official Transportation Data Archive for the Portland Metropolitan Region • Produce products that are useful to local transportation professionals as well as researchers • Explore new, innovative uses of data • Thank you!http://portal2.its.pdx.edu Need Pictures...
