Research Highlights

Modeling and Analyzing the Impact of Advanced Technologies on Livability and Multimodal Transportation Performance Measures in Arterial Corridors

Miguel Figliozzi
Christopher Monsere
This research proposes a novel approach to study the microscopic, intersection-level interactions of two advanced control technologies: SCATS adaptive traffic signal control and transit signal priority (TSP). These interactions will be studied using Powell Blvd (PB), which is a fully instrumented urban corridor in Portland, OR. The corridor is severely congested during peak periods and has low levels of service (LOS) for transit, and motor vehicles. and pedestrians. This research will mode... 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
