We're excited to place Capital Bikeshare stations in more neighborhoods throughout Arlington and will be doing so beginning in April and then July as more funding becomes available. In order to do this in a methodical manner, multiple divisions and departments within Arlington County, lead by Arlington County Commuter Services, came together to assist in developing the Capital Bikeshare Station Demand Map.* This map will serve as a guide as we determine where the future stations will go so that we continue to maintain a tight network of stations as we have done within the Route 1 corridor in our first round of Capital Bikeshare stations.
We created the map by begining with color-coding the County based on a) where the people are, with population and employment density; b) where bike facilities are, such as trails, lanes, and routes; c) where existing transit is and how well it's used; and d) some destinations, such as libraries and community centers that receive a lot of foot traffic.
On top of this, we divided the County into its neighborhoods and even smaller census block groups. With a calculation based upon the European model of bikesharing with a station every two blocks (1,000 feet) in high demand neighborhoods and every four blocks (2,000 feet) in low demand neighborhoods, and the area from which they draw riders, we are able to determine the number of bikes for each census block group. This number of bikes is shown within each census block group on the Capital Bikeshare Station Demand Map.
For census block groups with many bikes, this number will be divided up into a number of stations, composed of 11, 15, and 19 docks. The stations will be placed at high demand locations within each respective census block group, such as Metro stations, employment centers, retail, etc.
For census block groups with fewer bikes, the Capital Bikeshare station serving the neighborhood will draw from a larger area, serving two, three, or even four block groups as the demand for bikesharing is likely lower in these neighborhoods which are likely less transit-centric and more auto-centric.
The growth of Capital Bikeshare in Arlington will be based on government funding and the service's revenues, which include membership, usage, and sponsorship. As these funding sources become available, we will be able to install and operate more stations in more neighborhoods.
