My pal DT just sent this link to an interactive traffic map from the City of Ottawa. Built on Google Maps, you can view a variety of information overlays, such as construction zones, "incidents" (is that accidents or other significant traffic delays?), park-and-ride lots, and more.
I think the coolest thing is seeing what's currently displayed on "VMS" Message Signs around the area. Like this "deer warning" message on Frank Kenny Road in the eastern Ottawa.
