| Abstract: | By designing automated highway virtual field which has two-lane annular road with 80 meters curvature-radius, we gave the method of PN codes and curve information codes for magnetic markers in detail, and described vehicle positioning arithmetic. Also, in multi-path, vehicle can be exactly confirmed its driveway and its position of magnetic markers direction by matching its reading PN codes to replica. At last, we discussed coding method of multi roads such as high ways with on-ramp and off-ramp. |
