In recent years experiments have been conducted within the Pratical Trial Traffic Management Amsterdam with connecting and coordinating road sides systems and with the interaction with individual vehicles. Amsterdam has always been on the forefront of traffic management developments. This was confirmed with an article that was brought to our attention. This article (in Dutch) of author Joost van der Valk ('Roads' magazine, no. 9, October 1994) describes how Rijkswaterstaat applied traffic management in the region of Amsterdam.

From May 31st to June 5th, 2015 members of TrafficQuest (the Centre for Expertise on TrafficManagement) visited Austria and Switzerland for a study tour to learn how regions and cities dealt with (urban) traffic management and to see how these approaches could be used for the Dutch situation. The main question for this study tour was: How should the regions and cities handle the growth in traffic flows, both in normal situations and in situations where something special is going on? To answer this question, in five days four organisations that are busy with traffic management were visited in Austria and Switzerland: road authorities, manufacturer and a knowledge institute. The document "Study tour Austria – Switzerland: May 31 – June 5, 2015" contains a report of this trip and the lessons learned.

The application of flexible lane configuration for signalised intersections is sometimes beneficial for traffic delays, but sometimes not. This is the conclusion of the research conducted by Frank Anema and supported by TrafficQuest. He did his master thesis on this topic and received his MSc degree with the report entitled “Model-predictive control of the lane configuration at signalized intersections”.

Since 2008 an overview exists in which the results of (almost) all assessment studies for traffic management in The Netherlands are summarised. This is an important source of knowledge related to impacts of traffic management and is useful for policy and operations. TrafficQuest has updated this overview with the latest results and it contains now the research of 190 reports. The references of these reports are given in the de reference list. As usual, the number are contained in tables, given in this overview. Both are in Dutch.
