The one big advantage Perth stadium has is that it's on a peninsula, so there is no traffic other than people going to the stadium to cause congestion. Couple that with no car access and it means you can drive along the nearest road after the final whistle and not even know a game was on, other than seeing a few extra buses.Thanks for that detail. I remembered reading about the stadium when it was getting built and friends have since told me bits about the transport etc. As with the Perth example, the key for BMD is good public transport, getting people to and from the city centre, to shift the bulk of the fans most efficiently and not gridlock the roads with cars. A similar level of car usage as currently seen at GP would probably overwhelm the new site, which in turn could stifle shuttle bus operation due to limited number of roads available.
Whether BMD is set up to be able to provide something similar I don't know, but I think one of the biggest benefits would be if there were different bus stands taking people to different locations, not just to the city centre, eg turn left for buses direct to the northern suburbs, straight ahead for East and right for the city centre. The more directions people leave in, the less congestion
