A comprehensive programme of field trials with several new applications of dynamic (or variable) speed limits on motorways was carried out in The Netherlands in the years 2009-2010. The objective of the programme was to gain more insight into the impact of dynamic, tailor made speed limits on various policy goals.
Innovative solutions were developed, e.g.:
There were five field trials on four locations. All field trials were evaluated using loop detector data as well as camera data. Changes in driving behaviour, traffic flow characteristics, traffic safety, air quality and noise levels were analyzed. Also, a user acceptance study was carried out. This paper presents the overall results of the evaluation of the Dutch field trials with dynamic speed limits (Dynamax).
