Paths though Toronto

    Prev Next

    Routing 30,000 randomly-chosen trips through the paths suggested by 10,000 randomly-chosen geotags. These are perhaps the most interesting routes between the endpoints of the trips, even if not necessarily the most likely.

      Some information seems absent as there is not much representation of traffic along the Queensway and Gardiner Expressway. Is it because only a few suicidal types tweet while driving? There is no traffic along the GO Lakeshore Line which is strange since it is the most used of Toronto's commuter rail lines. Is it because trips have one end well outside the city limits? Queen West is unbelievably heavy for such a narrow street. Maybe more people in the cafés tweet? This seems likely as the heaviest lines are place where people go to socialize like the Danforth and Bloor West.

      As I said in the description, it's what would hopefully be the most interesting route to take between two places, not necessarily the most practical or more most likely route. And yes, you're right, trips that begin or end outside the area of the map are not accounted for, which can definitely skew the volumes.

      Despite the limits of this method, it certainly moves forward a really great idea. It's refreshing to think about cities in ways beyond the usual petty politics.

      This is a really cool idea.

      how does your algorithm decide if the person is using transit or driving, walking or bicycling and route according?

      In some cases you can guess from the speed at which someone is traveling what kind of transportation they are using, but I didn't make any attempt at that in this image. All geotags are treated the same here without regard to mode.
