The use of Open Data (OD) in an Engineering Asset Management (EAM) context is largely unexplored. Even though research into OD is moving forward, this knowledge is not fully usable in EAM because of the complexity and the specific characteristics of EAM. The research is centred around the case study that has taken place. As input for the case study, a literature review has been conducted to summarize and analyse the existing knowledge of OD and EAM. This created a starting point for the case study. A case about the traffic situation around the IJsselbruggen and the VIA15 project (A12) has been selected to research the possibilities to use OD with the goal to evaluate the current traffic measures and investigate the possibilities for Data-Driven Decision Making (DDDM). The combined results of the literature review and the case study have been reviewed by a group of experts in an expert workshop session. Besides there critical opinion about the research, the experts where also asked about their view on the use of OD in the EAM sector.
