    In DRIVE C2X project, the cooperative in-vehicle signage (IVS) function was tested in controlled field tests in the Finnish, Italian, and Spanish test sites and in naturalistic driving tests in the Swedish test site. The IVS function included child sign, yield sign, stop sign, merging sign, pedestrian crossing sign and pedestrian crossing ahead sign. A within-subject design was applied to study impacts that the function has on driver behaviour. The IVS function had indeed positive impacts, especially, in areas where special attention should be paid on vulnerable road users as IVS child sign and IVS 'pedestrian crossing ahead' sign had impact of reducing speed in their relevance area. In addition, there were some indications of smoother driving with the stop sign.
