Design and planning carried out by SINA focuses particularly on elements associated with the active safety (signs, lighting, etc.) and the passive safety (safety barriers, impact attenuators, protection nets, etc.) of transport infrastructure in order to guarantee high user safety.

On the subject of passive road safety, SINA, in collaboration with the most prestigious research centres and Politecnico di Milano, has developed and designed barriers and other similar systems which have undergone crash testing in accordance with EN 1317 and are CE certified.

SINA also carries out studies on new barrier and similar systems, certification through crash testing and verification of the installation criteria for barriers with the patented MARTE system (MAcchina per il rilievo della Resistenza del TErreno – machine for determining soil resistance).
