  The coordination and cooperation of all the stakeholders involved is a
decisive point for the control and the resolution of problems. In the
insecurity events, the resolution should refer to a plan that defines a general
framework of the procedures to be undertaken and the instructions to be
complied with; also, a more precise process must be defined by the actors to
deal with the case represented by the particular problem of the current
situation. Indeed, this process has to cope with a dynamic, unstable and
unpredictable environment, due to the heterogeneity and multiplicity of
stakeholders, and finally due to their possible geographical distribution. In
this article, we will present the first steps of validation of a collaborative
decision-making approach in the context of crisis situations such as road
accidents. This approach is based on ontologies and multi-agent systems.
