Breaking Barriers: Alternative Approaches to Avoiding and Reducing Highway Traffic Noise Impacts (1-2022)
The North American Bikeshare Association released the 2020 State of the Industry Report on shared micromobility systems (e.g., electric scooters and bikeshare systems). The report compares mobility patterns identified in the 2019 report and discusses trends observed in 2020, such as free and discounted rides offered to essential workers and an increase in first-time riders. The findings indicate shared micromobility ridership decreased in early 2020, but rebounded more rapidly than other shared modes.
