There has been significant progress in Europe toward the widespread implementation of road transport informatics (RTI), or intelligent vehicle highway systems (IVHS). A brief summary is offered of the more significant developments. These include route guidance system implementations in Berlin and London along with the major research programs DRIVE and PROMETHEUS. The goal of the DRIVE program, an EEC project, is to coordinate the many developments into a coherent integrated road transport environment (IRTE) in which a common infrastructure and standardized techniques, particularly for communication, are used in a number of application areas. The PROMETHEUS project is aimed at providing a common European traffic system that will increase traffic safety and maximize efficiency. >

Abstract : Some new schemes for encoding map data are introduced. The schemes can be regarded as generalizations of the well known 8-direction chain coding scheme. Instead of being limited to 8 types of links for approximating a curve, the new schemes possess 16, 24, 32, 48, or even more link types. The new schemes permit increased smoothness of representation, exhibit greater precision, and require less processing time for comparable resolution than present methods. (Author)
