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 cha...

In order to make sure bicyclists' needs are considered when improving a transportation system, planners and engineers need to know how many people are biking, and where.
Traditional bicycle counters can provide data for limited sections of the bike network, often these counters are installed at important locations like trails or bridges. While limited in location, they count everyone who bikes by. Meanwhile, GPS & mobile data cover the entire transportation network, but that data only rep...
