Ride Up and Be Counted—Seven New Bike Counters Installed

Permanent Bike Counters Map RESIZED

Seattle is working to make bike riding a comfortable part of daily life for people of all ages and abilities. Toward this end the Seattle Department of Transportation (SDOT) is constructing neighborhood greenways, protected bike lanes and multi-use trails; installing signs to guide people to their destinations; and putting in bike detectors at traffic signals. By creating comfortable places to ride bikes and connections to parks, schools and business districts, we hope more people will discover the practicality and joy of bicycling.

The next step is to monitor our progress. SDOT recently added seven new bike counters (four of which also count pedestrians) to neighborhood greenways and multi-use trails. The counters are helping us create a ridership baseline in 2014 that can be used to assess future years and help us reach our goal of quadrupling ridership by 2030. Unlike the two existing bike counters, on the Fremont and West Seattle bridges, the bike counters do not have electronic display totems. But that doesn’t make them any less valuable.

Three counters were installed on neighborhood greenways:

  • 26th Avenue SW at SW Oregon Street in Delridge
  • 39th Avenue NE at NE 62nd Street in Wedgwood
  • NW 58th Street at 22nd Avenue NW in Ballard

Seattle is building a network of greenways to give people healthy travel options and help move us toward our safety goal of zero traffic fatalities and serious injuries by 2030. The counters consist of two small tube sensors stretching across the street, which are attached to a small metal counting box made by Eco-Counter. The tubes only count people riding bikes. They are very accurate and designed to be used on greenways.

Four counters have been located on multi-use trails:

  • Elliott Bay Trail in Mrytle Edward Park
  • Burke-Gilman Trail north of NE 70th Street
  • Chief Sealth Trail north of S Thistle Street
  • Mountains to the Sound Trail west of the I-90 floating bridge

Multi-use trails link neighborhoods to business districts and create connections with recreational and natural areas within the Puget Sound region. Also made by Eco-Counter, these sensors count both people riding bikes and pedestrians. Separate volumes are tallied for each travel mode. Wires in a diamond formation in the concrete detect bikes and an infrared sensor mounted on a wooden post detects pedestrians. The counters also capture the direction of travel for both bikes and pedestrians.

Data from the counters will be downloaded at the beginning of each month. It will be uploaded to Data.Seattle.gov and be available for public use starting in February. All counts are recorded in one hour intervals and will include a total overall count and, as available, a directional count. SDOT plans to install at least three more counters this year. Additionally, numerous one week counts will be conducted at selected location throughout the city each year. The data from the permanent counters will enable estimates of annual bicycle volume to be calculated at the one week count locations.

Special thanks go to the Rails to Trails Conservancy and the Mark and Susan Torrance Foundation for funding half of the cost. The data counters installed on our multi-use trails will be used in the Rails to Trials Conservancy’s Trail Modeling and Assess­ment Platform (T-MAP). This is a $1.2 million, three-year initiative to create the next generation of trail planning data collection instruments, methodologies and analysis tools.
