The main objective of the TRA 2012 is to contribute to innovation in sustainable mobility for Europe, by bringing together all the stakeholders of the transport system. The TRA gives the opportunity to the road, rail and maritime sectors to address common challenges and share knowledge in order to deliver together a greener, safer and smarter transport system. In pursuing its objective of sustainable mobility for Europe, the TRA enhances the global competitiveness of the European Union, by promoting the three aspects of the knowledge triangle: Research - Education - Innovation. TRA 2012 will cover a wide spectrum of research and innovation activities. These will range from basic sciences to application oriented engineering and represent social, technical and economic aspects, aswell as policy and standards.  The TRA will also address demonstration activities. TRA 2012 will continue its tradition and hold an early-stage research student competition with the goal of stimulating the interest among young researchers in the conference. The TRA 2012 program will be organised into six pillars built around the European research and innovation strategies while emphasising on the issues of climate change, CO2 reduction, fuel efficiency and supply. Innovation in transport in Europe requires a multi-stakeholder and multi-disciplinary approach and so we invite you to share in and contribute towards this great challenge for a sustainable future in transport that lies ahead of us. We do sincerely hope you will join us at this innovative and exceptional event and share the information at your disposal. It will, as always, be the perfect opportunity to discuss the future of transport in Europe with all the stakeholders concerned. We very much look forward to seeing you in Athens in April 2012
