The World Road Association – PIARC implemented an ambitious PIARC Knowledge Exchange project, aiming at sharing knowledge about road safety, with the active contribution of NTUA and AIT, especially within Low and Middle Income Countries with limited resources but also in more developed economies with different needs and priorities. The theme of this month refers to tunnels, as presented by the chair of the PIARC Technical Committee 4.4 “Road Tunnels”  Ingo Kaundinya. Throughout the year, PIARC focuses on the Safe System approach, addressing safe roads and roadsides, safe road users, safe vehicles and safe speeds.  ppt5 video
