Andreas aka the London Cyclist timed trip times of some common journeys, riding his bike and taking the London Underground and comparing the times. You can read about his experiment here
In the various commuter challenges I've seen, bikes generally come out ahead of other transportation modes in urban environments, even beating out a helicopter in this challenge
. For many trips in Silicon Valley, I on my bike am often quicker than taking a VTA bus
, although Caltrain is almost always the quickest mode for longer trips.
