## 5 Conclusions  
This study provides a comprehensive assessment of technologies from European research projects relevant to the most recent EU 'Sustainable and Smart Mobility Strategy', making use of the technology-monitoring methodology developed by the authors for TRIMIS. The exercise of linking the technologies to the most recent policies provides useful information to policy makers in further specifying policy documents. It also helps them to specify future transport R&I needs, while at the same time, prioritising technology funding and avoiding funding overlapping. It can also contribute to the work of transport researchers who aim at gaining a better understanding on the evolution of transport technology. On a practical level, researchers can understand the historic evolution of a technology within the context of FPs, and identify areas for future development, something that can be helpful in preparing research proposals when applying for funding. Principal findings focus on the technology maturity of the technologies: mapping the various technologies and their development phases allows a clear view on the technological developments that can support the SSMS and future policies. This is important since technologies and policies are part of a cyclic process, with the former contributing to the timely adoption of the latter. Nevertheless, there are some limitations to this study. Most importantly, the technology assessment focuses on EU-funded projects, and consequently, not all conducted research is covered. In this sense, it would be valuable to complement the assessment with information on private R&D investments or data from intellectual property offices. Another limitation is that funds associated with each technology were determined by linking them with the total project budget. If multiple technologies were researched in the project, the budget allocated to the technology of interest was determined by dividing the project budget by the number of associated technologies. Despite the limitations, this approach is considered as appropriate and transparent in absence of specific technology-budget reports in EU funded R&I projects. Finally, in this exercise focus is given to selected technologies, in particular those that received most funding. Extending the analyses to the entire technology database goes beyond the scope of this academic paper. **Author Contributions:** Conceptualization, K.G., F.L.M.d.S., M.S. ; methodology, K.G., F.L.M.d.S., M.S. and F.P. ; software, K.G., F.L.M.d.S. and M.S. ; validation, K.G. and F.P. ; formal analysis, K.G., F.L.M.d.S. and M.S. ; investigation, K.G., F.L.M.d.S. and M.S. ; resources, F.P. ; data curation, K.G. and F.L.M.d.S., writing--original draft preparation, K.G. ; writing--review and editing, K.G., F.L.M.d.S., M.S. and F.P. ; visualization, K.G., F.L.M.d.S. and M.S. ; supervision, F.P. ; project administration, F.P. ; funding acquisition, F.P.
