Great pic.
I drive this section every day at rush hour. I know it's just a picture and we don't know what day that picture was taken - or the time of day, for that matter - but that traffic volume in the 80s looks similar to what I encounter today.
I've found that highways generally move pretty well as long as there aren't design shortcomings. I believe the 401 was redesigned in the early 2000s to add an additional lane in the westbound express west of Leslie, and it seems to work. All the hotspots for traffic in Toronto are due to a design flaw where the civil engineers didn't anticipate the user experience of the thousands of people who would travel through that stretch. These are things like lanes ending before a major exit and unnecessary on- and offramps that conflict with another entrance or exit causing drivers to weave. The axiom that adding lanes causes congestion doesn't really stand up in my experience. It's more where the lanes are added; if it's not to circumvent a bottleneck then, of course, you'll have problems.
If I could redesign just three highway locations in the GTA, they would be:
- eliminate the York Mills offramp and Fairview Mall onramp from the southbound 404/DVP;
- build a ramp from the southbound 400 to the 401 east express lanes (eliminating the needless lane changing to make it onto the basket-weave, which often backs traffic up to Finch) and maybe adding an additional lane on the eastbound 401 express at least as far as the exit for Yonge;
- eliminating the Dixon Rd./Martin Grove exit on the 401 to effectively turn the 401 stretch between the 409 and 427 into the "express lanes", with all collector traffic using the 409/427 combo instead.
