Abstract: This paper summarises the rapid progress in Europe in developing in-vehicle navigation systems. It discusses the various studies which have been carried out of the benefits of route guidance, distinguishing between 'static' and 'dynamic' systems and highlighting the significant levels of benefit which have consistently been predicted for dynamic route guidance systems. It describes the advantages specifically for the driver who has access to in-vehicle navigation. The autonomous systems Carin and Travelpilot are described, as is the Ali-Scout dynamic system which is the basis of the LISB trial in Berlin and its successor, Euro-Scout. The background is given to the Autoguide system proposed for London which could be the first fully dynamic route guidance system available on a commercial basis, including the legislative and implementation aspects and the current status of the pilot and full commercial systems. Developments using the Radio Data System Traffic Message Channel (RDS-TMC) for dynamic updating of Carin (Carminat) and Travelpilot are described. The UK dynamic system for motorways Trafficmaster is put into the context of other developments. The Drive project Socrates is outlined, with a discussion of the role of cellular radio in providing the basis of an Integrated Road Transport Environment (IRTE). Other developments within the Drive programme are summarised. The role of navigation systems within the Prometheus programme is reviewed, including a description of the 'Common European Demonstrator' project 'Dual-Mode Route Guidance.' In conclusion the merits of infrastructure-based dynamic route guidance and navigation systems are reviewed; parallels and contrasts are drawn between the European approach of Road Transport Informatics (RTI) and the US plans for Intelligent Vehicle-Highway Systems (IVHS).'
