Alternative Routes in Road Networks

Ittai Abraham, Daniel Delling, Andrew V. Goldberg, and Renato F. Werneck


We study the problem of finding good alternative routes in

road networks. We look for routes that are substantially different from

the shortest path, have small stretch, and are locally optimal. We formally

define the problem of finding alternative routes with a single via

vertex, develop efficient algorithms for it, and evaluate them experimentally.

Our algorithms are efficient enough for practical use and compare

favorably with previous methods in both speed and solution quality.
