INTELLIGENT SPEED ADAPTATION - DEVELOPMENT OF A GPS BASED ISA-SYSTEM AND FIELD TRIAL OF THE SYSTEM WITH 24 TEST DRIVERS

It is well documented that high speed is a key factor in car accidents. For many years, traffic calming and police surveillance have been the methods to reduce the speed of the cars. However, the development in intelligent transportation systems (ITS) has lead to the development of speed reducing systems. The general term for these systems is "Intelligent Speed Adaptation " (ISA). The ISA system establishes the position of the car, and the position is compared with a digital roadmap which contains the local speed limits. If the local speed limit is exceeded the system responds, e.g. a LED flashes. This paper presents a research project at Aalborg University in Denmark. The research project has developed an ISA-system (hardware and software). The system has been tested by 24 test drivers. The purpose of the test is to collect users' reactions to the system. The project has also investigated how the users' speed changes when an ISA system is installed in their cars. There is a detailed description of the project at www.infati.dk; at this site the results of the project will be published continuously. Also reference 1-3 can be downloaded from this site.
