Increasing or decreasing speed isn't the answer. Increase speed will cause way more accidents, decrease just spreads congestion over a larger area. There needs to be incentives for people to car pool or somehow get off the road. look around next time you're in a jam and you'll see 95% of the cars have 1 person in them. And also, Melbourne reduces limits down to 40, and closes a whole lane through the tunnel, over the wg bridge, in heavy congestion. So having to come down to 80 isn't really that bad.
