When I lived in Canberra a year ago I noticed some backed up traffic in peak time near EPIC - however I realised there was only one car lane in each direction, and one bus lane in each direction. I don't agree that we should always build more roads if there is traffic, but building a light rail solution when the bottleneck is one congested car lane each way seems a bit unusual.
