Another argument for biking transportationally: U.S. commuters wait approximately 40 mins. a day for public transit
See the article from Metro Magazine.
This reiterates a point I make often, that biking can be either a great substitute or a complement to riding transit, as a way to significantly improve the efficiency of the trip.
For example, when I lived at 6th and H Street NE, one of my jobs was in Crystal City. I didn't ride all the way to Crystal City but I rode to L'Enfant Plaza Metro and took the train three stops from there, rather than riding from Union Station to Gallery Place and transferring there. Another job I had was in Bethesda and I would ride to Dupont Circle and take the Metro from there.
Those are examples of biking significantly shortening trips by complementing transit. And obviously, trips you can take by bike exclusively are typically much shorter than transit when you take waiting into account.
From the article:
New York City: Respondents spend an average of 149 minutes on public transport each day, 38 minutes (26 percent) idly waiting for the bus or train to arrive, with a 40% dissatisfaction rate
Los Angeles: 131 minutes per day on public transport, 41 minutes (31%) waiting, 43 percent dissatisfaction
Boston: 116 minutes per day on public transport, 39 minutes (34%) waiting, 38% dissatisfaction
San Francisco: 104 minutes per day on public transport, 36 minutes (35%) waiting, 35% dissatisfaction
Chicago: 115 minutes per day on public transport, 31 minutes (27%) waiting, 19 percent dissatisfaction

That's something I haven't thought of mapping for the public outside of plans in quite the same way, although it has been done, for example in the publication by VeloQuebec (image below).
It would be a useful element to add to mapping illustrations of my "mobility shed" concept.
