On the Role of Warm-Up Detection in Multi-Level Traffic Simulations

The works proposed in this paper address the problem of the warm-up detection in the context of multi-level traffic simulations. Such phenomenon, called also “initialization Phase” is of a most importance since it defines the fluctuations which appear during the transient phase. The main characteristic of the warm-up phase is the state instability during the traffic flow simulation and its duration cannot be known in advance. The main objective consists in eliminating the warm-up phase by dynamically transforming macroscopic simulation to a microscopic one.
