Investigating Effects of TNCs on Parking Demand and Revenues
Benjamin Clark Anne Brown
For the past century, mobility in the United States has been dictated by cars. Furthermore, cars—and even more so, the storage of cars—have dictated urban form. With cities dedicating more space to parking than even streets and roads, parking has become baked into city land use, regulations, codes, ordinances, master plans, and even finances. What happens when a car trip no longer ends in a parking space? Both transportation network companies (TNCs) and, eventually, autonomous vehicles (AVs),…

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,…
