The global aim of PREVENT Pre-Commercial Procurement is to augment the security in public transport through innovative procurement of technology solutions. The proposed technologies will endow Public Transport Operators with solutions enhancing security situational awareness through: i) Timely automatic detection of potentially dangerous unattended items in Public Transport Infrastructure and in public areas in the vicinity; ii) Identification and tracking of perpetrators; and iii) Advanced crisis management system. The PREVENT PCP project builds on the outcomes of its predecessor PREVENT, and it continues the top-down approach that allowed consolidating commonly agreed scenarios, covering the critical security issues down to a detailed identification of the complete set of innovation needs, both at process and technology levels, to ease coordination across the full chain of stakeholders, from transport operators to security forces and public authorities. Therefore, the need for innovative solutions stems from a longer collaboration and is driven by commonly identified internal needs to improve the quality and efficiency of pre-empting terrorist attacks. The project will conduct a phased Pre-Commercial Procurement composed of: Phase 1: To finalise the tendering documents package already prepared under PREVENT CAS; Phase 2: To implement the call for tenders for research and development services; Phase 3: To conduct the competitive development of the prototypes following the PCP principles (design stage, integration & technical verification stage and validation in real environment stage); Phase 4: To consolidate the results of the evaluation of the developed prototypes, extract conclusions and recommendations from the validation process, and to define a clear strategy for the further uptake of solutions. PREVENT PCP involve 13 public buyers coming from 6 different EU countries and will validate 2 different prototypes in 4 pilots: France, Spain, Portugal and Italy.
