Road Ecology Course and Seminar Series

Mark Sytsma
The American road network is a major economic investment that is a major organizing force for human activity. The road system has profoundly altered ecological processes and, as a result, it is also an important organizing force for ecosystems. Understanding the ecological consequences of road system design and use is critical to effective engineering and management of road systems to minimize impacts. I propose a new course within Environmental Science and Resources at PSU that will expose u... Read More

Multimodal Data at Signalized Intersections: Strategies for Archiving Existing and New Data Streams to Support Operations and Planning

Christopher Monsere
Kristin Tufte
The Portland (OR)-Vancouver (WA) metropolitan region's officially designated archived data user service PORTAL - the Portland Oregon Regional Transportation Archive Listing - has undergone the transition from a pure research project to a regional resource. At present, however, PORTAL primarily contains vehicle observations on freeways. The freeway coverage is robust and detailed: traffic observations of speed and count every 20 seconds from 671 loop detectors (at about 100 stations) and detai... Read More
