Portland SMART Grant: Zero Emission Delivery Zones

John MacArthur Nathan McNeil
In Spring 2023, the Portland Bureau of Transportation (PBOT) was awarded a Stage-1 grant under the Strengthening Mobility and Revolutionizing Transportation (SMART) Grants Program by the US DOT, titled “Decarbonizing Goods Movement: A Technology-Enabled Zero Emission Delivery Zone.” The City of Portland will launch a 25-acre Zero Emission Delivery Zone (ZEDZ) in central downtown to implement a regulated zero-emission zone. Funding for this Stage One SMART grant will allow PBOT to trial… Read More

Affordable Housing Trip Generation Strategies and Rates

Kelly Clifton Kristina Currans , Susan Handy , Robert Schneider
Assessment and mitigation of transportation impacts based on travel demand is required by state, federal, and local laws in California. Determining trip generation is typically the first step in preparing these transportation impact analyses, and current industry standard practice relies on trip rates published by the Institute of Transportation Engineers (ITE). However, ITE protocols emphasize vehicle trip rates without sensitivity to urban context or socioeconomic characteristics, which can… Read More
