Which trips by taxi should people consider replacing with bicycling?

This map displays all taxi trips that began and ended in Boston between May and November 2012, minus trips where the distance exceeds five miles and where it appears there were errors in data collection.* Bicycling is faster than taxi for the trips displayed in green and slower for the trips in red.

*The start and end points were the same, or the end time was earlier than the start time.
