Abstract
Traffic management applications are supported by dynamic models fed with realistic real-time demand matrices in order to find efficient solutions in the short-term horizon. OD matrices have to be estimated from historic or real-time data collection and prior matrices. In this work, we present a simulation-optimization Bilevel-DUE approach for Dynamic OD matrix estimation suitable for off-line application, in which the lower level consists on a dynamic user equilibrium problem solved by a mesosco...
