Report details simpler way to track freight on Oregon’s highways
Freight transportation is an important part of Oregon’s economy. Helping the statewide freight-transport system run more efficiently means better understanding the movements of trucks on the highways. By monitoring the progress of individual trucks, the Oregon Department of Transportation can obtain valuable performance metrics such as travel time, travel delays, and origin-destination flows. This information can help identify slow passages or bottlenecks in the highway system.
Tracking individual trucks, however, can be problematic. To follow the movements of a truck on the freeway, typical methods might include putting in automatic vehicle identification (AVI) tags, or acquiring a license-plate-recognition system to be used at checkpoints. For ODOT, this could mean purchasing expensive new equipment. Moreover, these tracking methods can raise privacy concerns.
In an OTREC-sponsored research project, Portland State University’s Chris Monsere looked into alternative methods for obtaining those helpful freight metrics without installing tracking units in every single truck. The details of Phase 2 of the project, which expand upon and further refine the results of Phase 1, can be found here.

Vehicle reidentification is the process of matching vehicles from one point on the roadway to the next. With the process developed by Monsere this can be done anonymously, and inexpensively, using tracking methods that are already in place. Oregon’s highways, like elsewhere in the US, are dotted with weigh-in-motion (WIM) and automatic vehicle classification (AVC) stations. At these stations, vehicle attributes including truck weight, axle spacing and axle weight are recorded.

New report shows a better way to track freight over highways
Freight transportation is a vital component of Oregon’s economy, and many expect shipments to nearly double in the next decade. Making informed decisions to better manage the freight transportation system requires monitoring freight movement and freight transportation performance. Because most of that freight moves by truck, this means better understanding those trucks’ movements.
Existing methods for tracking individual trucks can require buying expensive new equipment, however, and raise privacy concerns. In his report, “Exploratory Methods for Truck Re-Identification in a Statewide Network Based on Axle Weight and Axle Spacing Data to Enhance Freight Metrics,” Christopher Monsere investigated an alternative: Using only existing vehicle sensors, is it feasible to reidentify trucks after they have traveled long distances?
Monsere and his research team used data from existing weigh-in-motion stations, which record axle weight and spacing and gross vehicle weight. They then developed and applied algorithms to match truck measurements at separate sites, allowing them to reidentify the same vehicles at other weigh stations.

Dr. Figliozzi Selected to lead development of truck efficiency report
Miguel Figliozzi, OTREC researcher, has been selected to chair a study group that will assist DEQ in developing a report, including recommendations for legislation regarding truck efficiency, reduced idling, and emissions. This report will be submitted to interim environment and natural resource committees of the Oregon Legislature by October 2010 for their consideration and any possible action during the 2011 legislative session. The 2009 Oregon Legislature adopted House Bill 2186, which directed DEQ to study potential requirements regarding the maintenance or retrofitting of medium- and heavy-duty trucks in order to reduce aerodynamic drag and otherwise reduce greenhouse gas emissions. DEQ also plans to study potential restrictions on engine use by parked commercial vehicles, including but not limited to medium- and heavy-duty trucks. Study group members will work with DEQ staff to report findings and recommendations for legislation to the interim legislative committees on environment and natural resources by October 1, 2010.

ITS Lab Students and Faculty Active at National Urban Freight Conference October 2009
Portland State University faculty and students presented their work at the National Urban Freight Conference (NUFC) in Long Beach, CA October 21-23, 2009. Dr. Miguel Figliozzi presented "Emissions & Energy Minimization Vehicle Routing Problem" and "A Study of Transportation Disruption Causes and Cost in Containerized Maritime Transportation." Also, graduate research assistants Ryan Conrad and Nikki Wheeler presented research projects sponsored by OTREC. Ryan presented "Algorithms and Methodologies to Analyze and Quantify the Impacts of Congestion on Urban Distribution Systems Using Real-world Urban Network Data" and Nikki presented "Analysis of the Impacts of Congestion on Freight Movements in the Portland Metropolitan Area." NUFC brings together researchers and practitioners in the public and private sectors from many disciplines within freight transportation. This conference is the only one of its kind in the US, and brought attendees and presenters from across the US, Canada and Europe.
