Interestingly, even though the CaBi station at 16 & Harvard was expanded from 15 to 32 (or 33) docks yesterday, it still ran empty by 9:00 AM this morning. It started the morning at 7:41 AM with 28 bikes and by 8:44 AM, it was fully depleted. What a well placed expansion!

*I recently updated cabitracker to allow passing dates into the station page. Use the format above, s=[start date] e=[end date]. we=false will turn weekends off and wd=false will turn weekdays off. It requires both start and end times if you wish to pass in dates.


Great analysis. I'll add that yesterday, this station ran out of bikes at 8:04 AM, while today it ran out at 8:44. For someone like me that's a late riser, that's a pretty important extra 40 minutes.

Thinking about this more broadly, I wonder if CaBi will follow the fundamental rule of traffic engineering, which is that as you build extra capacity, that capacity is almost immediately used up as more people choose that mode. For highway engineering, this is the poison pill behind every "we'll widen the road to relieve congestion" argument, however, since CaBi is a significantly more benign mode of personal travel, this principal works in its favor, and argues for significant and rapid expansion.

Will, you're right that the station ran empty at 8:04 on Tuesday.

A similar thing happened Monday. However, that is not the normal trend. Look at the month of October, excluding weekends:
You'll see that the station hit its lowest number of average bikes available during AM rush hour at 8:33 AM.
