  • Transit is a small but important part of the research that OTREC has funded. It’s typically undertaken by a 3 core researchers at PSU. Jim Strathman is the main investigator and is with the college of urban planning. Miguel Figliozzi focuses on freight and logistics and operational issues.
  • Empirical analysis of these incidents draws on a wide array of operator-level data recovered by transit ITS technologies in combination with information from TriMet's human resources, scheduling, and customer relations databases. Incident frequencies are estimated in relation to operators' demographic characteristics, employment status, assigned work characteristics, service delivery and performance indicators, temporal factors, and customer information.
  • ITS Lab Students Submit Video to RITA's Challenge - July 2011 Students from the Intelligent Transportation Systems Lab at Portland State University have submitted a video in response to the ITS Video Challenge is sponsored by the U.S. DOT Research and Innovative Technology Administration, Federal Highway Administration, and Federal Transit Administration The video is located here. The team is made up as follows: Eric Albright (student), Brian Davis (student), Wei Feng (student), SirishaKothuri (student), Peter Koonce (PSU Professor), Carl Olson (student), Courtney Slavin (student)

      Static & Dynamic Visualization of TriMet’s Route 15 Bus Performance
      Wei Feng, Scott Price, Krissy Hostetler, Dr Miguel Figliozzi, Portland State University
      Dynamic visualization allows transit agencies to see how bus operations propagate over time and space.
      The Issue: How to convey large amounts of data in a comprehensive format?
      The “fog of data”:
      the dilemma of having too much information. 
      Color-coded diagrams can help quickly identify issues either for a certain time period, or for a single stop during a single time period.
      3 ways the visualization techniques improve the generation & display of performance measures
      easier to understand - draws attention to specific stops & time periods
      Ability to conduct spatial and temporal analysis along a route
      Animating bus operations helps to see how bus performance propagates

    • 113. Vehicle Mileage Fees
      • Why? The gasoline tax is no longer sufficient in funding transportation operations, maintenance, and infrastructure.
      • 114. How? Analysis of data collected from ODOT road user fee pilot project.
      • 115. Findings:
      • 116. Drivers do respond to peak fees, but varies by day of the week
      • 117. Impact of change to vehicle miles traveled (VMT) fee on rural areas was less than expected. On average a household in rural location would pay less under revenue neutral VMT fee. Urban households would pay slightly more
      • 118. Access to transit and other alternatives may be important
    • VMT &Economic Activity
      • Why?To help understand the effect that metropolitan GHG/VMT reduction policies will have on the local economy.
      • 119. How?Look at how determinants of VMT differ between Urban Areas such as availability of transit, industry structure, urban density, etc.
      • 120. Implications:Results should help make informed policy choices for GHG reduction that may differ between UAs.
    • Green Transportation Fees
      • Why? Inadequate revenue from current transportation user fees and low public acceptance of increasing fees/taxes
      • 121. What? Fee rates that vary based upon the environmental characteristics of the vehicle
      • 122. How? Random survey of Californians
      • 123. Findings:
      • 124. “Green” fees made fee increases more popular
