  This paper aims to provide insights related to the impact assessment and
evaluation results from the use of CITS services in the Greek pilot of the
CRoads Greece project, i.e., Attica Tollway and Egnatia Odos Tollway. The
impact assessment and evaluation of the CITS services includes aspects related
to user acceptance, real world pilot logs collected from the two pilots, and
simulation experiments that were conducted for the impact assessment of the
CITS services. The paper concludes with a roadmap and guidelines for the
extended deployment of CITS services in the Greek highway and urban road
networks.
