Where is my Streetcar?
This Google Map shows the real-time position of streetcars in Toronto.
Using the map you can find out how long you will have to wait for a streetcar at any of the city's stops. You can select your stop from a drop-down menu at the top of the map and you can choose to view either westbound or southbound streetcars or both.
The real-time position of the streetcars are then displayed on the map with arrows that display their direction of travel. The map uses City of Toronto Open Data, using feeds provided by NextBus and the TTC.
The whole project is open source, so if you think you can improve the map you can view and edit the source.
