We introduce an improved algorithm to locate a segment highway such that the maximum city distance between a given set of $n$ points is minimized (where the city distance is measured with speed $v>1$ on a highway and 1 in the underlying metric elsewhere). We consider that such highway is built in a complex transportation system with $H$ other highways and obstacles. The algorithm runs in $O(n^3 H^3(\log^2 n + \log H))$ time using $O(nH)$ space improving the previous $O(n^4 H^4)$ time and space bound. |
