1. can the air navigation aid of flexibly regulating path planning, in order to judge whether vehicles should turn at a crossing, and to adjust path planning in good time, it is characterized in that, the method comprises following step:

  • A () obtains a travel speed of these vehicles, and calculate a braking distance and a reaction distance to obtain a safe distance by this travel speed, this safe distance is that this braking distance adds this reaction distance, this braking distance be this travel speed square divided by the acceleration of gravity of twice again divided by a friction factor, reaction distance is the product in travel speed and reaction time, wherein, the reaction time refer to driver'"'"'s eyes see and pin touch on the brake between the reaction time that must exhaust;

    B () obtains the positional information instantly of these vehicles, and calculate a turning distance at this this crossing of vehicle distance whereby;

    AndC () judges whether this turning distance is less than this safe distance, if so, then path planning again.
