TTC passenger map (revised)

Sorry it took so long to come up with a revised TTC passenger map (see previous post). First I had to come up with the appropriate formula in Excel (thanks to the NICAR listserv for explaining what that would be and why.) Then I lost my KML radius generator magic – I’m still not sure how that happened.

Then there were the usual minor weirdnesses – Midland station ended up off the coast of Peru in an early draft.

In any case, this version of the TTC map shows circles proportionately sized by area showing the typical number of customers travelling to and from each station platform on an average weekday. This technique could be used for other kinds of data, one reason I wanted to get it right.
