Transit Time Machine
Eric Fischer brings us a time machine, in more ways that one. (No, this does not involve a hot tub on Muni (though that could be surprisingly entertaining.))
First is a 1913 transit time isochron map for the Peninsula and East Bay to 3rd and Mission — steam and electric trains, as well as ferries. Surprisingly fast, and for the Peninsula, not all that different from today (which makes me very sad).
Also, a 1933 isochron map. (Geary Street, if only…)
Finally, Eric’s datavisiogeniusness brings us this map of where 45 minutes of Muni gets you.
White dots are where vehicles were located the indicated time after they had been to 3rd and Market.
Green dots are where these vehicles had been earlier in their trips from 3rd and Market.
