Intelligent Speed Adaptation in the City of Stockholm: Implementation Strategy and Status.

The City Council of Stockholm has decided that all vehicles belonging to the City of Stockholm will have Intelligent Speed Adaptation (ISA) before 2010. An implementation strategy has been adopted focusing on what steps must be taken in order to: fulfill the implementation goal; to achieve an effect on driving behavior; and to obtain acceptance among the drivers. These steps include both technical and practical issues: such as the procurement of the ISA-system; technical requirements; speed-limit data; and management and cooperation with other actors. This paper will present the main issues of the implementation strategy and status of ISA in the City of Stockholm.
