The San Francisco region has joined the bikesharing movement, with the introduction of Bay Area Bikeshare in August 2013. I wanted to see if I could adapt any of my CaBi tools for the “BABS” system, but their open data is too limited to be of much use. They have a System Metrics page which offers only ridership and membership data, which is not very interesting. To analyze the system we need trip history data, like Capital Bikeshare shares every quarter.

Luckily, I discovered Eric Fischer, who has been tracking station statuses since late August. Every minute, he records the number of available bikes and docks at each station. While not as valuable as trip history data, this data does let us discover when stations are either full or empty.

The data he records is a copy of the current station data, available at bayareabikeshare.com/stations/json. I had to reduce the size of the file by writing a Java program to remove redundancy and unnecessary fields. Still, storing data for a single day takes a megabyte of space for even the condensed JSON file. » Continue Reading…

Bay to Breakers is an annual race in San Francisco, where runners traverse the city from the Bay of San Francisco to the Pacific Ocean. But what makes it special is that somehow, somewhere along its 102-year-old history, it also turned into a gigantic day-time costume party for thousands of people who have no intention of running.

I joined the race at 6th & Howard, more of a parade by the time I arrived at 8:30am, 90 minutes after the start a mile away. By this time the course was filled with people in costume casually walking, and at times limbo dancing. The weather was sunny. I walked almost 7 miles to the end point at Ocean Beach, arriving long after the course had closed. Most of the partiers walked to Golden Gate park and just stayed there.
