Today the Dutch cabinet provides in implementing a maximum speed limit of 130 km/h on Dutch motorways as much as possible. As a consequence, research is needed to the circumstances where and when higher speed limits (or maybe a dynamic speed limit) will be acceptable. In other words, what speed limit is the most optimal for a road section taking the traffic flow, the environmental targets and the safety issues into mind? In order to do the research, an assessment framework for a new speed policy is developed. With an assessment framework, the speed limit on a road section can be assessed. A more optimal speed limit can be determined, either permanent or dynamic for that road section. After finishing the research, it can be concluded in general that the road authority desires lower speed limits than currently applied and that the road user desires higher speed limits, but it is the question whether or not 130 km/h is the optimal speed limit for the road user.
