Infrastructural measures are used to reduce driving speed on four 80 km/h roads in the province of Drenthe, without additional enforcement and information. The aim is to obtain a permanent reduction in driving speed, and hence in accidents. The applicability of various models, based on performance theory and other areas of psychgology are assessed: tracking models, information-processing models, mental load models, speed perception models, utility models and behavioural models. An underlying basic principle that may be discerned is some kind of balance between costs and benefits. This implies that drivers may be influenced by increasing the costs or decreasing the benefits of speeding. For each of the benefits of speeding. For each of the models it was assessed what aspects of the road environment and infrastructure adds to the balance, and how it may be influenced. (A)
