Methodology: Attitudes survey and real-world trial in France with 90 drivers comparing advisory to intervening ISA.
The system was triggered on every type of road, but this occurred more frequently on urban roads than on n-class rural roads and motorways.
The system was overall very reliable, provided map-matching could be accomplished.
Advisory ISA reduced speeding for almost all speed limits (the exception was on 45 km/h roads), but it was substantially less effective than both the forms of intervening ISA tested.
Advisory ISA reduced the amount of time spent speeding by 10.5 per cent overall but there was a reduction of only 3 per cent on 50 km/h urban roads.
Intelligent Speed Adaptation
Results appear to be applicable to the UK.
