Transportation Research

The Intelligent Transportation Systems Laboratory website contains details about current and previous research projects, students and activities. We moved into brand new state-of-the-art laboratories and office space in January 2006. PSU is part of the new Oregon Transportation Research and Education Consortium which offers additional research opportunities. Some focus areas of our faculty include:

  • Intelligent transportation systems
  • Transportation data archiving/mining
  • Land use and access relationships
  • Transportation safety and security
  • Multi-model traveler information
  • Traffic flow theory and operations using real time data
  • Pricing and auctions in trucking and freight
  • Urban distribution systems and the impact of congestion of urban commecial vehicle movements
  • Freight data collection issues in urban areas
  • Vehicle routing in dynamic and time dependent environments
  • International freight movements and the determination of freight volumes and freight corridors
  • Urban freight systems
  • Vehicle routing in stochastic and time dependent environments
  • International freight and logistics
  • Supply chains and freight transportation sustainability
  • Pricing and auctions in trucking and freight
  • Freight data collection and performance measures
  • Freight mode choice and demand modeling

Research Facilities

Intelligent Transportation Systems Lab (EB315, 1200 sf) - The Intelligent Transportation Systems (ITS) Lab at PSU was developed in partnership with public agencies and industry and supports both research and performance monitoring. The lab houses a regional transportation data archive—Portland Oregon Regional Transportation Archive Listing (PORTAL portal.its.pdx.edu) — that continuously collects and archives high-level transportation activity in the Portland, OR metropolitan region. This archive includes volume and speed observations from area freeways at 20-second intervals, actual signal and phase time information from 400+ traffic signals, volume counts from arterial stations, hourly weather observations, incident dispatch logs, variable message sign logs, pedestrian activations at equipped traffic signals, travel times from fixed MAX readers, bicycle counts, and stop-level transit activity. These data are stored on high-capacity server. On staff is a staff software engineer with time dedicated to PORTAL and a project manager.

Transportation and GIS Lab (EB375, 585 sf) - The lab contains approximately 12 PC workstations with access to our central server and data repository. State-of-the-practice software in travel simulation, geographic and spatial analysis, travel demand, and statistical analysis software allow our research groups to study and analyze large scale systems. The lab has the full ERSI Arcview GIS suite installed on all PC and 10 TransCAD software licenses. The lab also has access to Portland’s extensive GIS data in the Regional Land Information Service (RLIS).

Traffic Signal Lab (EB380, 905 sf) - The lab contains 8 PC workstations with access to our central server and data repository, real-time access to the City of Portland’s traffic surveillance and central signal system,  functioning traffic controllers, 2 Controller Interface Device (CID) to allow hardware in the loop simulation, a suitcase signal tester, and timing optimization software. The software and equipment in this lab support research of the systems integration of traffic signals in the intelligent transportation system with a strong focus on data processing of traffic signal information. The lab has 5 full PTV America VISSIM/VISSUM/VISTRO licenses.

Transportation Data and Surveying Lab (EB390, 632 sf) - The transportation data surveying lab houses our field-based data collection equipment. This includes devices to measure speed (Ultralyte Lidar Gun) and vehicle counts (Autoscope Rackvision, 2 Wavetronix  side-fire radar monitoring devices, 12 pneumatic road tubes), and  bicycle and pedestrian counters (2 Eco-counters). The lab has 2 portable 2-input video data collection units and 2 4-channel portable video collection units.  The lab also includes high precision surveying equipment including total stations and single person roving GPS data collector.

Transportation Emissions Air Quality Lab (TEAQ) (EB390, 632 sf) – The lab has a) portable air quality equipment (PM, CO, CO2, total VOC) that can be deployed to measure pollution levels at any sidewalk/area location; b) portable temperature, relative humidity, and 3-D anemometers to record atmospheric conditions and portable video cameras to record surrounding activities. These data sources can be complemented by c) ITS traffic/transit data d) data from permanent PBOT air quality stations installed at a sidewalk location and  e) data from a permanent  ODEQ (Oregon Department of Environmental Quality) AQ/Weather station (ODEQ can provide useful background data).

Research Assistantship Opportunities

We have many opportunities for qualified graduate students. Any of the faculty would be more than glad to answer any questions you might have about the program, the assistantship package we can offer you, and living in Portland. Finally, the transportation group has funding available that could help support a visit to our campus for well qualified graduate students.
