Pull over strategy for the evacuation of an emergency vehicle in   highways
  By using a simplified two-lane cellular automata model for traffic flow, we simulate an evacuation of an emergency vehicle (EV) in highways. We introduce the pull over strategy to facilitate the evacuation of the EV in highways. We demonstrate numerically that this pulling over of cars promotes a faster moving of the EV in traffic flow and minimize the EV's impact on the overall traffic.
