Gaining knowledge about the effects of traffic management is useful and necessary, both for policy formulation as for traffic operations. On a strategic level decisions are made which alternatives to invest in are most feasible and cost effective and on an operational level the impact of a traffic management scenario is studied to improve traffic operations. In The Netherlands a lot of attention has been paid to the evaluation of traffic management measures. Since 2008 an overview exists in which the results of evaluations studies are presented in a comprehensive manner. Recently, TrafficQuest updated this overview with the latest studies, with makes that the overview contains the results of more than 175 evaluations. The references are given in this list
(in Dutch) and the results itself are summarised in a presentation
(also in Dutch only). In the future the results will be presented in a more accessible way and also in English.
