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.
