Abstract

In the autumn of 1996, approximately 100 professional and private drivers in the Swedish city of Umea were given the opportunity to drive with equipment for Dynamic Speed Adaptation, a so-called "Speed Checker". The electronic device, mounted on the vehicle dashboard, signals by light and sound if the driver exceeds the prevailing speed limit. The Speed Checker is activated by roadside radio transmitters, and is also linked with the vehicle speed metering system. Interviews were held with the users before and after the test period. The Speed Checker was preferred to physical means for speed reduction (road humps, etc.). The share of the Speed Checker equipped drivers keeping the speed limits increased from 25 to 80% during the test period. 90% of the users wanted the Speed Checker system to be expanded, and 95% wanted to keep the equipment in their vehicles for a prolonged period. The field tests continued until summer 1997 when additional interviews were held. Early results from these interviews show a continued support for the Speed Checker.
