Pedal Map

I love Citi Bike. As of the writing of this blurb, I have taken 1,959 rides, covered 3,600+ miles, spent 360+ hours biking, and saved countless minutes by not having to rely on the subway for intra-Brooklyn travel.

This site uses the General Bikeshare Feed Specification endpoints that Citi Bike publishes to show live bikes, open docks, e-bikes, station capacity, and whether a station is actually accepting pickups or dropoffs, refreshed every 15 seconds or so.

The data aggregation layer lives in a small separate service. Every hour it fetches station status, refreshes the station catalog when needed, and updates compact weekday/weekend hourly averages for each station. Once a day, another job finalizes average station ranks and removes expired daily summaries. The station table stays live by reading the public feed directly, with only a small daily rank snapshot coming from the historical database.

I want to give props to bikemap.nyc, who made an awesome project visualizing a Lyft data dump of user rides. Give it a visit.

The project is open source and available at mattbolanos/pedal-map, if you're into that kind of thing. If you want to support the project or just say thanks, you can buy me a coffee.
