Seattle's First Bicycle Counter

The bicycle counters on the Fremont Bridge and Spokane Street provide valuable information about the patterns of cycling in Seattle, and an accurate count of the number of cyclists at two of the busiest cycling locations in Seattle. They allow more accurate benchmarking for goals to increase cycling as set forth in the Bicycle Master Plan. The detailed information provided by these 24/7/365 counters will enhance SDOT’s ability to measure return on investment in bicycle facilities and help identify locations for new facilities. All of this while encouraging an affordable, healthy mode of travel that reduces greenhouse gas emissions and relieves congestion. The counters upload data once a day at 5am, which is then displayed in daily, weekly, monthly, and annual running totals.

The interactive charts below show hourly data collected by the Fremont Bridge bicycle counter and were created using Tableau software.
The first tab display temporal plots of the aggregate data (both northbound and southbound volumes) by month, day of week, and hour of the day. Interactivity allows users to isolate a specific month or day of the week.

The second tab plots the hourly aggregate data against hourly weather data at the University of Washington campus collected by the University of Washington Atmospheric Sciences department. Interactivity allows users to select the weather variable and choose specific time periods.

Tableau software users can download this data as a Tableau Workbook. The raw data can be downloaded in tabular format from data.seattle.gov. For more information please contact Craig Moore, Craig.Moore@seattle.gov or 206.684.5099.
