The Dutch Ministry of Transport (Rijkswaterstaat) has initiated a trial involving intelligent speed adaptation (ISA) for passenger cars in an urban area for a one-year period. Four speed limits ranging from 18 km/h to 80 km/h are used. A major evaluation objective is to assess the public acceptance of a drastic, speed enforcing ISA application against the background of the primary policy objective to examine whether ISA is a realistic option for speed control. Data on the acceptance of ISA, for various traffic conditions are provided. As the study involves both experimental drivers and reference groups, the impact of ISA exposure is identified, taking into account impacts for non-ISA vehicle drivers. ISA exposure is broken down into information provision, interaction with ISA cars and driving an ISA car. For the covering abstract see ITRD E114174.
