The number one worst aspect of the Perimeter is the unsignalled, at-grade crossing. Everyone one of those should be closed immediately or changed to an on-demand light for cross traffic but with a good delay built in too.
In terms of upgrades, I strongly feel the Perimeter does not need six lanes free flowing the entire length it covers. If we could add an extra pair of lanes that basically go interchange to interchange with a forced exit, and good warning signage, then the existing two lanes would be used far more efficiently. As it stands now there are places where you have merging traffic exiting a hairpin turn and dropping immediately into the 100 KM/H lane. This effectively means that for some stretches the Perimeter has
a single lane of free flowing through traffic.
My other suggestion would be to look at all the other at-grade access points and determine the distance to the nearest signalled or grade separation access and work on plans to close them based on short to longest distance. Some for example, the access point on the west side just north of CentrePort Way might not have a good alternative currently. Others, though such as the dirt road about a mile east of HWY 6 might be better of directed to entering the road crossing the Perimeter.
The final thought is a plan needs to be put in place that says: no new access to the Perimeter unless it is either a complete replacement for an existing signalled intersection or it is will fully grade separated from the start. Then say a new development like Southpointe is being planned and needs access the costs for the grade separation would be on the table for discussion as part of approval for their plans.
