In addition to recommending Capital Bikeshare locations, DDOT published maps showing some of their analysis to determine the locations:

This is the “heat map” showing the locations people selected on the online survey. A light green dot seems to represent a single selection, and when more selections are close to each other, the dots combine into brighter colors.

This map combines planning factors DDOT used to determine a priority for sharing stations. According to the key, it gives points to areas for being within ¼ mile of bus stops, within ¾ mile of a Metro station or MARC/VRE station, within ¼ mile of a bike lane or trail, and for employment density, population density, and bike to work rate.

Finally, since Arlington has already released planned locations for the Crystal City/Pentagon City bike sharing stations, BeyondDC combined the two into a joint map:

The Crystal City stations seem to have similar density to downtown DC. The heat map analysis also shows substantial demand along the Rosslyn-Ballston corridor. We already knew Arlington hoped to expand there next, but the Crystal City BID contributed to the initial Arlington stations, which is why they’re there.
