Evacuations with cars are a bottleneck
Evacuations with cars are a bottleneck
A highway camera photo shows traffic in FortMcMurray jammed in the southbound lane of Highway 63 on the north side of the Athabasca River. The image was captured at 3:11 p.m. MT, about an hour after an evacuation order was issued for four neighbourhoods. (511 Alberta)

notice the empty highways. the emergency personnel arent trained to reverse highways in this area, which is a common thing in certain places
also; fuck cars
Yeah on the Texas gulf coast they open up the shoulder into an additional lane and switch direction of the opposite side giving anywhere from 6-8 lanes. This lets them evacuate places even like Houston pretty quickly
Which leads me to believe that this area is actually trained to reverse lanes, but there was no urgency with this slow moving fire.
This and at least with fires there tends to be a lot of incoming resources. Depending on access, condition, and what not. It may be deemed that they need those lanes for emergency personnel.
I lived in Florida for a long time and when there are major hurricanes you have lots of people heading north. I've seen them reverse some lanes on the opposite side but keep one for south bound movement. Normally the only people headed in the other direction are emergency workers and its not enough to need more than one lane.
That is true but you have a lot more resources coming to a fire then showing up before a hurricane. I am not saying you have two lanes worth, but with the possibility of smoke obscuring visibility. The emergency vehicles are often given little more room. Also they often have to run with emergency lights at all times. So that is what you are expecting to see. Not someone in a little gray Honda.
I don't know if that is what is happening here, but it is a reasonable possibility.
"Pretty quickly" is still like 5mph maybe during peak evacuation traffic from a major hurricane. Smaller hurricanes aren't a problem because so many people choose to stay after horrible experiences trying to evacuate before: safer to stay home than be stranded on i10.
Not criticizing, but isn't it generally though that more lanes doesn't equal less traffic, or is a huge surge like am evacuation different?
More lanes == less traffic is wrong due to induced demand. In an evacuation, however, the demand is already at its maximum. What you want is more throughput to get the people out.
Having less lanes won't make people choose going on train or bus instead. Chances are that the busses and trains are already full.
