nickb800: They have to do something about the induced demand that will follow the road opening. Otherwise we'll get gridlock on sh1 through to the city and spend billions fixing it.
Scarcity of parking in the CBD might be sufficient alone - people will think twice about driving if we have Auckland level daily parking fees.
Just raise them to London levels and I guarantee that they will think a lot more than twice about it!
Except it failed miserably. Now mainly only rich people drive into central London. When it was introduced, it was rare to see a car in central London, and was mainly used by buses and taxis. Tolls are a class thing, as rich people don't need to worry as they can afford to pay tolls easily. Where poor people pay a higher percentage of their earnings if they need to pay a toll.
I don't think primary roads into a region, including SH1, should be tolled. If TG is tolled, why on earth wasn't the Waterview tunnel project in Auckland tolled? eg Why are Wellingtonians being treated worse than Aucklanders?
Has the Waterview tunnel incurred this "induced demand" problem? Or was the supply of traffic already saturated?
