Shapely: 라인스트링에서 가장 가까운 점 얻기

안녕하십니까,
한 점이 주어지면 선스트링에서 가장 가까운 점을 얻으려고 합니다. 간단한 선스트링에 대해 잘 작동하는 것 같습니다.
Python 3.4.0(기본값, 2014년 4월 11일, 13:05:11)

shapely.geometry에서 점 가져오기, LineString
라인 = 라인스트링([(0,0),(5,7),(12,6)])
p = 포인트(4,8)
np = line.interpolate(line.project(p))
인쇄(np)
포인트 (5 7)

그러나 복잡한 선스트링의 경우 의도한 결과를 얻지 못하고 있습니다.eg
