Personally I don't think it will help enough to justify the cost of rolling this out, that said I think we might see a bit more congestion in the surrounding areas of the city if people aren't willing to pay to use a road.

Having a work car and being based in the city, I've experienced just how frustrating the roads now are.
CHOGM was bad enough by itself but having the major roads through the city being reduced or restricted due to road works has made the place a nightmare to get through some times.

Surely there has to be a better way to remove the congestion in the city, perhaps building some multistory parking complexes North, East and West of the city would be a start.
Extend the Cat Buses to include these parking complexes and it might make a bit of a difference, then again give Perth another 10 or 20 years of growth and we will just be back at square one again.
