  1. TMIP Webinar: Using Visualization Techniques to Communicate Transportation Planning Data Christopher Monsere Assistant Professor, Civil and Environmental Engineering Intelligent Transportation Systems Laboratory Maseeh College of Engineering and Computer Science Portland State University November 13, 2008

  2. Outline • Our data archive – PORTAL • Data visualization examples • Fuel prices and travel • Green transportation measures • Freeway operations • Transit system performance • Freight system performance • Questions

  3. Portland, Oregon

  4. Portland, Oregon

  5. PORTAL -- Region’s ADUS

  6. What’s in the PORTAL Database? Loop Detector Data 20 s count, lane occupancy, speed from 500 detectors (1.2 mi spacing) Incident Data 140,000 since 1999 Bus Data 1 year stop level data 140,000,000 rows Weather Data Every day since 2004 001590 Days Since July 2004 About +700 GB 6.9 Million Detector Intervals VMS Data 19 VMS since 1999 WIM Data 22 stations since 2005 30,026,606 trucks Crash Data All state-reported crashes since 1999 - ~580,000

  7. Performance Measures Used • Volume • Speed • Occupancy • Vehicle Miles Traveled • Vehicle Hours Traveled • Travel Time • Delay

  8. Planning-Operations Connection • Planning for Operations • Regional Concept of Transportation Operations Grant • TSMO & ITS in RTP and TIP • MPO Committees • Congestion Management • Non-recurring • Reliability • System management • Links to freight and demand management

  9. Data Visualization Examples • Fuel prices and travel • Green transportation measures • Freeway operations • Transit system performance • Freight system performance

  10. Fuel Prices and Travel Measures

  11. Green Performance Measures

  12. Factors Affecting Emissions

  13. Emissions Estimation

  14. I-5 MP 302.5 (1.4 mile section)

  15. I-5 MP 302.5 (1.4 mile section)

  16. Note: There are many other factors (temperature) and sources (non-mobile) for CO in Portland. This was simply a sample visual comparison, not a correlation analysis.

  17. Freeway System Performance

  18.

  23. Mapping – Speed By Month July 2005 December 2005 Average Evening Peak Speed (5-6 pm)

  24. Metropolitan Congestion Over Time Winter Spring Summer Fall 2004 2005 2006

  25. Mapping – Speed Subtraction Average Evening Peak Speed (5-6 pm) Difference July-December 2005

  26. Data Quality Reports • Stations Reporting (June 2006 weekdays): • No Traffic (all lanes) > 20% of Samples • Communications Failure > 15% of Samples

  27. Incident Reports Incident on NB I-205, log truck rear-ended a nursery truck, two cars also involved, duration over 4 hours. Incident on SB I-205, NB effects visible

  28. Monthly Incident Reports Incident Types Number of Lanes Affected Incident Locations Number of Ongoing Incidents Number of Incidents Time
