City of Ann Arbor Open Data Portal

Downtown Development Authority (DDA) Bikeway Counters

The City’s first two-way protected facility, the William Street Bikeway, was installed in 2019. Three others have since been added: on First Street, Division Street, and Miller-Catherine. Counters have been installed that count bikes in the bikeway and pedestrians on the adjacent sidewalk.

Please Note: 2023 does not reflect a full year of bike and pedestrian activity. The first counters were installed in August and September of 2023. September 2023 contains a full month of data for the Division and William counters. Data for the Miller/Catherine counter begins on September 5, 2023 in the afternoon. A fourth counter, located on First St., was installed on October 2, 2024.

Bike count data does not include scooters.
