Research Highlights

Oregon Freight Data Mart

Miguel Figliozzi
Robert Bertini
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 an...

Evaluation of Bicyclists Exposure to Traffic-Related Air Pollution along Distinct Facility Types

James Pankow
Miguel Figliozzi
Very few concurrent measurements have been carried out on cyclist physiology with air quality, and no measurements that incorporate detailed traffic data. Due to this lack of knowledge, there are significant uncertainties and debate about the net health effects of cycling as a means of transportation in heavily trafficked urban areas. It is perhaps even astonishing that there are currently neither guidelines nor even a moderate understanding of cyclists\\\' uptake of urban pollutants when tra... Read More
