Research Highlights

Application of Smart Phone Truck Data for Freight Performance Measures and Transportation Planning

Miguel Figliozzi
Freight data is usually incomplete, scarce, and expensive to collect due to carriers and shippers' privacy concerns and the enormous variety of supply chain types and decision makers. This project will study a new, inexpensive yet highly promising source of freight data that provides commercial vehicle origin-destination, space/time coordinates and trajectories. This new data can also be integrated into existing data sources to provide a wealth of information including commercial vehic... Read More

Analysis of Travel Time Reliability for Freight Corridors Connecting the Pacific Northwest

Miguel Figliozzi
Due to its geographic location, Oregon's economy is highly dependent on reliable transportation. Recent studies indicate that projected growth in freight and passenger traffic will significantly increase congestion and travel time delays. Further, it is predicted that congestion may result in a potential income loss valued at $1.7 billion annually in value added generated in Oregon by 2025, and a loss of 16,000 ongoing jobs(ERDG, 2005, ERDG, 2007). Most supply chains cannot thrive wi... Read More
