Abstract

A six month national Field Operational Test (FOT) with more than 1 100 drivers using a Speed Alert function integrated in GPS-equipped cellular phones has been conducted in Sweden. Focus of the FOT was to study how a Speed Alert system should be designed to achieve as high acceptance as possible of the individual users. This differs this study from earlier studies on Speed alert or ISA that has primarily focused on speed reduction on the cost of acceptance. The drivers have been logged and interviewed with regard to their use, acceptance and experience of the system. From the study conclusions about traffic safety effects and implementation strategies are drawn. The field trial ended July 31st and results will be presented at the conference.
