Just a point that was made at the time and it may be too late,
The reason for making Edward Street one way was because the Bendi buses could not pass each other.
The out come of making the street one way will mean coming down the hill in order to get into town you will now have to join the queue of traffic before turning left in Gt Pulteney St. before it was so easy to go straight across at the roundabout.
The easy no expense option is for the drivers of the bendi buses to have their own un offical one way rules.

perhaps this is too simple!!
