      Collision avoidance analysis for lane changing and merging 

      Jula, H.; Kosmatopoulos, E. B.; Ioannou, Petros A. (2000)
      One of the riskiest maneuvers that a driver has to perform in a conventional highway system is to merge into the traffic and/or to perform a lane changing maneuver. Lane changing/merging collisions are responsible for ...
