1. A method for determining a traveling condition of a host vehicle during an exit from a main road to an access road, comprising:

  • accessing, with a processor, a host vehicle position;

    accessing, with the processor, road network data including road types;

    accessing, with the processor, road surface marking property data including road surface marking positions;

    based on the host vehicle position, the road network data, and the road surface marking property data, determining, with the processor, that a condition of the host vehicle corresponds to an exit start scene when a position of a broken line marking in front of the host vehicle and a position of zebra zone in front of the host vehicle match, the broken line marking indicating an exit section; and

    determining, with the processor, an exit start timing of the host vehicle when the condition is determined to correspond to the exit start scene by;

    obtaining a relative distance between the host vehicle position and a reference point indicating an end point of the exit section when a length of the broken line marking is equal to or greater than a predetermined length; and

    determining that the exit start timing has arrived when the relative distance is shorter than a predetermined length and the host vehicle has crossed the broken line marking.
