HOV lanesI think HOV is next to useless. The permanency of the lane is pretty poor, seems to change with the change of government!
During heavy load, a small number of motorists will violate the lane, which will then induce everyone to violate the lane which then completely cancels out any benefit of the lane at a time it is needed the most.
It is dreaming to think motorists will not cross a 2.5 inch white line during heavy congestion to take advantage of the HOV lane time benefits even though they might not be entitled to it. And what evidence is there in Brisbane that these things work anywhere. What are the mean travel time savings and is that enough to get people to use the HOV lane?
And another thing- are these HOV lanes going to be brand new lanes or are they going to come from the conversion of where bus lanes are?
Exclusive bus lanes are better IMHO.
Even ones that are exclusive only during peak hour and controlled by variable signs or lit road markers.
HOT lanes These might work, but again, where is the location? If it is down, I don't know, Kelvin Grove road, you may as well resume that lane and put a tram line or superbus lane down it.
The toll is very good at keeping people out of the lane. Provided Buses and taxi and motorcycles could ride in the HOT lane for free, then it might work, but again I can't really see it having a huge impact in the overall scheme of things.
