Exploratory Methods For Truck Re-Identification In A Statewide Network Based On Axle Weight And Axle Spacing Data To Enhance Freight Metrics, Christopher M. Monsere, Mecit Cetin, Andrew Nichols

TREC Final Reports

The main objective of this project is to evaluate the feasibility of re-identifying commercial trucks based on vehicle-attribute data automatically collected by sensors installed at traffic data collection stations. To support this work, archived data from weigh-in-motion (WIM) stations in Oregon are used for developing, calibrating, and testing vehicle re-identification algorithms. The vehicle re-identification methods developed in this research consist of two main stages. In the first stage, each vehicle from the downstream station is matched to the most “similar” upstream vehicle by using a Bayesian model. In the second stage, several methods are introduced to screen out those vehicles …

Oregon Freight Data Mart, Miguel A. Figliozzi, Robert Bertini

TREC Final Reports

Increasing freight volumes are adding pressure to the Oregon transportation system. Monitoring the performance of the transportation system and freight movements is essential to guarantee the economic development of the region, the efficient allocation of resources, and the quality of life of all Oregonians. Freight data is expensive to collect and maintain. Confidentiality issues, the size of the datasets, and the complexity of freight movements are barriers that preclude the easy access and analysis of freight data. Data accessibility and integration is essential to ensure successful freight planning and consistency across regional partner agencies and planning organizations. In relation to …

Transporting The Economy, Miguel Figliozzi

TREC Project Briefs

The efficient, timely and reliable movement of freight is a critical responsibility of the transportation system and strategically important to the U.S. economy. Today, Americans purchase billions of dollars worth of goods over the Internet for home delivery, routinely sent using nextday- express packages. They also expect globally produced fresh fruits, flowers and vegetables to be available year-round. These shipments move over an extensive freight transportation system comprising millions of vehicles and thousands of miles of road, track and pipeline infrastructure, all supported by sophisticated information technology and operated, managed and maintained by a large, specialized labor force.

These are …

Distribution Logistics Course, Miguel A. Figliozzi

TREC Final Reports

Commercial vehicle movements associated with the delivery of goods and services are currently experiencing a number of challenging problems. Carriers and fleet operations face congestion, a growing number of tolls, increasing service level demands, and in some cases opposition due to the externalities caused by freight traffic in urban areas. This course provided a greater understanding of the complex issues surrounding urban freight and logistics and it was relevant to graduate students in civil engineering, urban planning, and business programs.
