Research Highlights
Mode-Based Benefit-Cost Analysis Calculator
Jenny Liu
Transportation decision-makers typically use benefit-cost analysis (BCA) to evaluate the tradeoffs of transportation projects. However, it is difficult to produce state-specific measures that are multimodal and can consistently evaluate the full range of public and private benefits and costs for Oregonians. Supported by a $200,000 grant from the Oregon Department of Transportation (ODOT), Jenny Liu of Portland State University will lead a research effort to develop an Oregon-specific,…

Network Effects of Disruptive Traffic Events
Juan Medina Xiaoyue Cathy Liu
Current traffic management strategies are based on expected conditions caused by recurring congestion (e.g. by time of day, day of week), and can be very effective when provisions are also given for reasonable variations from such expectations. However, traffic variations due to non recurrent events (e.g. crashes) can be much larger and difficult to predict, making also challenging efforts to measure and forecast their disruptive effects. This project explores a proactive approach to manage non…
