The “Eco-Totem” counter (made by the Montreal-based company Eco-Counter) counts cyclists via in-ground loop detectors embedded under the pavement of Broadway near Kendall Square. The device displays on a monitor how many cyclists pass by, and data is transferred in 15 minute increments daily from the device to Cambridge's Open Data Portal. Funding for this project was generously provided by the Helen & William Mazer Foundation.

This bicycle count data is collected as part of the City of Cambridge’s regular citywide bicycle counts. These counts are typically done on weekdays (Tuesday-Thursday) in September, annually between 2002-2006 and every other year since 2008, with an additional count in 2019 due to poor weather in 2018.
