Abstract

We propose an algorithm for the point-to-point time-dependent shortest path problem, using which good solutions may be found in a short time; our method provides an upper bound to the number of settled nodes for each shortest path computation, which is highly desirable in some industrial applications. In particular, we address a typical server scenario, where we have to compute point-to-point shortest paths in road networks where arc costs (travelling times) are time-dependent, and where each request has to be provided within an allotted time frame.
