In recent years the Dutch government has developed a new warning and alarm system for crises andemergencies. Called NL-Alert, it uses cell broadcast techniques, meaning that messages are sentthrough the radio masts of cellphone providers. To receive NL-Alert messages you need a correctlyadjusted cellphone. The aim is to use NL-Alert for sending short and clear alarm messages. The systemis intended to be supplementary to existing alarm systems.Towards the end of 2011 the Dutch government wants to make a decision about the introduction of NLAlert.The decision will be partly dependent on various tests. This survey on people’s thinking andperception is part of these, together with three practical tests.The survey focuses on the actual reception of NL-Alert messages, the willingness to act and the generalperception of and attitude towards this kind of crisis communication.Definition of objective and questionsThe object of this survey is to provide insight into the extent that people can receive messages throughNL-Alert and how they think about this sort of warning system.The survey is focussed on the following research questions:1.
