Who are the Users of Speed Regulation Assistance? Comparing Driver Characteristics of Casual and Intensive System Users

Speed regulation assistance can contribute to road safety provided that drivers use the systems on a regular basis. With the objective to gain knowledge about drivers who use Cruise Control and the Speed Limiter, a comparison of the characteristics of casual and intensive users was performed with survey data. The results show that gender and annual mileage play a role for the usage frequency of Cruise Control, whereas the usage frequency of the Speed Limiter depends on age. Consistent effects of the car use for business matters and the use of other in-vehicle technologies were found on the usage frequency of both systems. The predominant motive to reduce speeding found for both systems corresponds with the objective of speed regulation assistance as a safety measure. It was complemented with a comfort benefit perceived by Cruise Control users.
