The project entitled "TRICS+ Safety-related effects" is a joint-venture project between the Swedish National Road ADminsitration (SNRA), VTI ( the Swedish Road and Traffic Research Institute), LTH (The Lund Institute of Technology, the institute of traffic engineering and Transek AB. The project is designed to analyse and summarise the available research and finally to describe the traffic safety effects which will result from future road systems being influence by dynamic and autonomous speed adaption systems. This has been done on the basis of different scenarios, using an approach similar to that employed in the TOSCA I and II studies but nontheless more restricted since the only area to be studied was speed adaption systems as a transport telematic application in the analysis of traffic safety effects. The objective of this project was to identify applications for a dynamic speed adaption system which is of interest and the effects it will have on the traffic system in general. Other objectives were to clarify the way speed adaption systems can influence driver behaviour and to clarify the new demands which may be imposed on vehicles, road administrators and regulations in future traffic systems.
