  Traffic evacuation planning can be essential in saving lives in case of
natural disasters such as hurricanes, floods and wildfires. We build on a case
study of traffic evacuation planning for the city of Mill Valley, CA. We run a
microscopic traffic simulator to examine various evacuation scenarios. We
modify some crucial aspects of a previous study to make the simulation more
pertinent. For a citywide evacuation, we quantify the importance of decreasing
the number of vehicles per household. We find a set of changes that can
significantly reduce the evacuation time by routing more traffic to the
least-used highway on-ramps. We show results when evacuating various areas of
the city one at a time.
