Side shape；The zone location each summit polygonal is referred to as control vertex；Control vertex described in each
All it is control point；The collection at all described control point is combined into control point set；
3) geographical coordinate at all control point is calculated：According to the geographical coordinate in location information, course over ground,
The position at each control point, and installation site, the installation direction of satellite positioning antennas, calculate institute
There is the geographical coordinate at control point；
4) set of the road area that the vehicle is currently located is found out：Search in all of setting road area
The set of the road area that each control point of vehicle is located；The collection of the road area that all control point are located
The intersection of conjunction is the set of the road area that the vehicle is currently located；
The step 2) optionally also include following process：To the polygonal each edge of the zone location successively
Process：From the beginning of an end points, to another end points direction, every the length of a setting, increase by one
Control point；Exist without the polygonal summit of zone location so that quick detection goes out, but have zone location polygon
Side pass through road area；
The step 2) optionally also include following process：1 is arranged in the zone location polygonal internal to arrive
N number of control point；
The step 2) the polygonal constructive method of the zone location, can also be：The projection polygon
Summit or side on 1 to N number of point, move in or out less than distance set in advance, described each
Point according to movement before adjacent be linked in sequence, the polygon of composition is zone location polygon.
