Christopher Higgins , Andrew Nichols
The objectives of this research are to: 1.) collect, sort, filter, and archive WIM data to permit development of long-term continuous records of high-quality WIM data and; 2.) use the WIM data archive to monitor WIM sensor health, develop loads for asphalt design, load models for bridge rating and deck design, and monitor freight movement on the highway system, specifically the volume, weight, safety, and time demands. Researchers will collect WIM data from DOT agencies (ODOT and others natio... Read More

Using Existing ITS Commercial Vehicle Operation (ITS/CVO) Data to Develop Statewide (and Bi-state) Truck Travel Time Estimates and Other Freight Measures

Christopher Monsere
Robert Bertini
The transportation of freight is an important component of the Oregon economy. The Federal Highway Administration estimates that from 1998 to 2010, the total tonnage of freight shipments to, from, and within Oregon will have increased 50% and the value of those same shipments nearly doubled. While other modes are clearly important for freight transportation, trucking is the dominant mode in terms of tons and value. Currently, there is no system that estimates travel time for many major freigh... Read More
