SOCRATES stands for "system of cellular radio for traffic efficiency and safety". The paper assesses the status of the development of SOCRATES systems in Europe, providing an update on what many consider to be the technology with the greatest potential for successfully achieving the realisation of an integrated road transport environment (IRTE). Using SOCRATES, computers in vehicles receive detailed up-to-the-minute information about traffic conditions. Drivers receive guidance on the best routes and relevant information to help them complete their journeys. SOCRATES services will integrate with public transport and parking information in order to help to use the complete transport infrastructure most efficiently. Other services available using SOCRATES will include an emergency call facility and fleet management applications. The trials described include: a) RHAPIT; b) APPLE; and c) TANGO (traffic information and navigation for Gothenburg). (a)
