Why Is This An Indicator Of Health and Sustainability?

Cycling as a driving alternative reduces traffic-related noise, air pollution and congestiona and improves personal health through increased physical activity.  Encouraging and facilitating active transportation – walking or cycling - as a form of travel for utilitarian trips is a key strategy for increasing daily physical activity.b  Personal health benefits of increased physical activity in children and youth include enhanced cardiorespiratory and muscular fitness, bone health, body mass and composition.  In adults and older adults, strong evidence demonstrates that, compared to less active counterparts, more active men and women have lower rates of all-cause mortality, coronary heart disease, high blood pressure, stroke, type 2 diabetes, metabolic syndrome, colon cancer, breast cancer, and depression.

Interpretation and Geographic Equity Analysis

All bike share locations are currently on or adjacent to the section of Market St. that runs through the Financial District and South of Market, due to hospitable topography, job density, access to local and regional transit and proximity to the bicycle network.  This location strategy is intended to support transit users on the first or last mile of their trip. The bike share locations that are adjacent to the largest percentage of jobs in San Francisco are those at Market and Sansome, Market and Battery, and Beale and Market, in the heart of the Financial District.

Methods

SFMTA provided the XY coordinates of the bike share stations and the number of docks. The job density data at the block group level was pulled from the Longitudinal Employer-Household Dynamics. To calculate the number of jobs within 1,000 feet of the bike share station, a 1,000 feet buffer was created around the bikeshare stations. Job from the block groups that fell within the buffer were summed for each bikeshare station and then divided by the total number of jobs in San Francisco.

Limitations

The Bay Area Bikeshare program in SF was part of a regional effort funded by MTC to reduce greenhouse gases and address climate change. SFMTA utilized this opportunity to help address the problems of the first and last mile of trips for commuters. Therefore, the stations are grouped mostly in Financial District and SoMa. It is important to note that it takes time to build a robust bike share network and this program is a pilot.
