When the COVID-19 pandemic first swept across North America and led to emergency shutdowns during the Spring of 2020, the way people acquired food and household necessities was dramatically impacted. As stay-at-home orders minimized personal travel, transit services were reduced and many stores and restaurants either closed or modified their operations. Some of the gaps were able to be filled by online retailers and delivery services. However, access to goods and services varied substantially depending on people’s age, income level, and physical ability. A new multi-university study funded by the National Institute for Transportation and Communities (NITC), the U.S. DOT- funded university transportation headquartered at Portland State University, and the National Science Foundation (NSF) captured how households responded as local, state, and federal governments imposed and lifted restrictions, brick-and-mortar establishments closed and reopened, and e-commerce and delivery services adjusted to the changing conditions.

This paper describes research undertaken to establish plausible fuel-speed curves (FSC) for hypothetical advanced powertrain vehicles. These FSC are needed to account for the effects of congestion in long-term transportation scenario analysis considering fuel consumption and emissions. The results presented in this paper will assist analysis of the roles that vehicle technology and congestion mitigation can play in reducing fuel consumption and emissions from roadway travel.
