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.
