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...

Taxing Shared Micromobility: Assessing The Global Landscape Of Fees And Taxes And Their Implications For Cities, Riders, And Operators
John MacArthur
Shared micromobility (including shared electric scooters and bikes provided by private companies) is one of the newest transportation options that has come to cities in the last several decades. A new report explores the different ways cities charge shared micromobility companies to operate, and how these funds are used.
In the newly released report, John MacArthur of Portland State University, Kevin Fang of Sonoma State University and Calvin Thigpen of Lime examine data from 120 cities in...
