A Dynamic Discretization Discovery Algorithm for the Minimum Duration Time-Dependent Shortest Path Problem

Conference paper
Part of the Lecture Notes in Computer Science book series (LNCS, volume 10848)


We present an exact algorithm for the Minimum Duration Time-Dependent Shortest Path Problem with piecewise linear arc travel time functions. The algorithm iteratively refines a time-expanded network model, which allows for the computation of a lower and an upper bound, until - in a finite number of iterations - an optimal solution is obtained.
