For the Round Table 'Effects' (organised by DITCM and Connecting Mobility) TrafficQuest has contributed to a new way of looking at the evaluation of C-ITS and Automated Driving. It is a cyclic view on evaluation that has the advantage that not only the impacts of different systems and services are determined, but that these results are also put into perspective. This can be done using the results of other experiments or of experiments under different circumstances (meta-analysis), but also by relating the results to policy goals and drawing generic conclusions about the impact on a national level or with different penetration rates (scaling). Eventually, these steps lead to new questions and hypotheses, which can be tested in new experiments. An extensive description of the evaluation circle is given in a report 'Evaluation of C-ITS and Automated Driving'.

Several cooperative ITS services (C-ITS) are currently being tested in the Netherlands. With these in-car systems and services road users are informed, warned for certain situations on the road and advised to change their driving behaviour. It is expected that a lot of these services will be implemented in the coming years, not only on the motorway network but also in cities. Due to the experimental character of these services and their number and diversity, it is difficult to draw general conclusions about the (potential) effects. A lot about the impacts is still unclear. Rijkwaterstaat has asked TrafficQuest to do a quick scan on the effects of C-ITS, especially on road safety. The available literature was read and analysed and the numbers that were mentioned in these studies were summarised. The results of this quick scan are described in this memo (in Dutch).

The Natonal Traffic Congress 2016 was attended by more than 400 traffic and mobility professionals. They listened and talked about among others urban mobility, road design and big data. TrafficQuest had 2 contributions this year, both papers for discussion (in Dutch). One paper deals with the requirements from road authorities that can be specified for C-ITS applications, which are now in development everywhere. The paper discusses new control possibilities that become available if information is exchanged between traffic signal control systems and road users. In the session the persons present could vote on propositions that were put forward. Based on the outcome the discussion was held.
