Intelligent transportation systems are of great importance in urban traffic management. In this context variable message signs (VMS) play a major role in providing drivers with useful information during their trips.ududIn this paper we consider the problem of finding the optimal location of a set of portable VMS on an urban network where flow patterns change during a time horizon.ududWe propose two original solving approaches based on flow intercepting facility location ILP models.ududThe paper presents an application of the proposed approaches to real-like test networks and discusses the results obtained providing some indications on their practical applications.
