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, multimo...
