Dutch Evaluation of Chauffeur Assistant (DECA) : traffic flow effects of implementation in Heavy Goods Vehicles sector

This report concludes the second phase of the Dutch FOT (Field Operational Tests) examining the effect of lateral support systems, in particular the traffic effects of the Chauffeur Assistant (CA) Driver Assistance System. The research includes a worldwide literature study, assessment in the TNO Human Factors driving simulator of the (changes to) driver behaviour with CA, and finally the incorporation of the literature review and the driver behaviour analysis in the TNO Inro MIXIC (Microscopic model for simulation of Intelligent Cruise control) traffic simulation model which was subsequently used to asses the effects of CA. The CA control algorithms were developed by TNO Automotive and TNO Human Factors, based on information provided by Daimler-Chrysler in terms of the HMI (Human Machine Interface) and functionality of the CA. The scenarios analyzed in the traffic simulation model included trucks and passenger cars, but only only the trucks had the CA equipment.
