Intelligent Transportation Systems: Saving Lives, Time and Money Kristin Tufte, Robert L. Bertini, John Chee, Rafael J. Fernandez- Moctezuma, Sathish Periasamy, Shreemoyee Sarkar, Poonam Singh, James Whiteneck, Spicer Matthews, Nevin Freeman, Soyoung Ahn Jan 12, 2010

Intelligent Transportation Systems: Saving Lives, Time and Money  PORTAL established 2004 ◦ Simple web interface, single data source  Now ◦ 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

Intelligent Transportation Systems: Saving Lives, Time and Money  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-driven graphical 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 from diverse sources ◦ Functionality grouped by freeway system subset (system, highway, station)

Intelligent Transportation Systems: Saving Lives, Time and Money

 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.

Intelligent Transportation Systems: Saving Lives, Time and Money  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

Intelligent Transportation Systems: Saving Lives, Time and Money  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.)

Intelligent Transportation Systems: Saving Lives, Time and Money

 Next Steps ◦ Expansion to Vancouver, WA ◦ Increased use of Transit Data ◦ Sustainability/Green Metrics  Funding: TransPort MTIP (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! Need Pictures... Still thinking on this one…
