The benefits of implementing appropriate resilience management strategies into transportation systems can be measured in terms of safety, efficiency and even sustainability. To objectively identify the best strategies to boost resilience, different resilience assessment tools exist providing the response of the system when suffering and recovering from disturbing actions. In the case of road traffic networks, examples can be found where reliability, network connectivity, fluctuations in traffic flow, and even the stress of users as a consequence of the disruption are used to assess the system resilience. The real traffic network Luxembourg (Luxembourg) - Metz (France) is used in this paper to analyze the importance of information management to increase the resilience of a transport system under different sources and levels of traffic disruption. Different strategies aiming to modify users' behavior are discussed, showing that traffic response is more complex than initially expected, and how some traffic models might provide an incomplete picture about the traffic performance leading to non-optimal solutions when building resilience.
