In recent years the Dutch government has developed a new warning and alarm system for crises and emergencies. Called NL-Alert, it uses cell broadcast techniques, meaning that messages are sent through the radio masts of cellphone providers. To receive NL-Alert messages you need a correctly adjusted cellphone. The aim is to use NL-Alert for sending short and clear alarm messages. The system is 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 and perception 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 general perception of and attitude towards this kind of crisis communication. Definition of objective and questions The object of this survey is to provide insight into the extent that people can receive messages through NL-Alert and how they think about this sort of warning system. The survey is focussed on the following research questions: 1. To what extent do people receive a message through NL-Alert? 2. What perception do people have of NL- Alert, regarding the message itself as well as compared with the traditional system of warning through sirens? 3. To what extent do people intend to follow the action perspective that is given through NL-Alert?
