The Pre-LSDemo project has published a new report examining the main barriers to the large-scale deployment of Connected, Cooperative and Automated Mobility (CCAM) technologies in Europe and identifying priority evaluation topics for future large-scale demonstration projects.

The report, Barriers to Large-Scale Deployment of CCAM in Europe and Priority Evaluation Topics for Future Demonstration Projects, is based on two online surveys conducted with Pre-LSDemo partners and external experts and stakeholders from the wider CCAM community. The findings were subsequently reviewed and refined through a dedicated Pre-LSDemo expert workshop.

The study identifies 12 high-priority barrier themes and 13 priority evaluation topics. These include technical, regulatory, societal, operational, infrastructure, economic and transport-system integration challenges. The report emphasises that large-scale CCAM deployment requires these different dimensions to be considered together, rather than focusing on vehicle technology alone.

Overall, the insights from this study indicate that CCAM deployment is hindered by a combination of technical, regulatory, societal, operational, infrastructure, integration, and economic barriers. The clear overall message is that large-scale deployment cannot be achieved through vehicle testing alone; the problems across vehicles, infrastructure, digital systems, operators, regulations, public authority approvals, user acceptance, and business model requirements must be considered together. Experts most frequently raised technical, societal, and regulatory barriers. Many barriers also cut across several categories. For example, an issue that is primarily technical, such as safety validation, can also affect approval processes, liability, public trust, procurement, and long-term business viability.

Safety validation and ODD/safety-case credibility was identified as the highest-priority barrier, while real-world safety/ODD validation was identified as the highest-priority evaluation topic in this study.

Among the highest-priority barriers, besides validation and Operational Design Domain (ODD) specification, the report indicates business models and scalability, technical robustness in real-world conditions, and regulatory uncertainty, approval pathways, liability and cross-border harmonisation. Other important areas include public trust and user acceptance, infrastructure and connectivity readiness, operational feasibility, multimodal integration, inclusion and accessibility, data governance, and stakeholder coordination.

The corresponding evaluation priorities include, besides real-world safety and ODD validation, system-level traffic, environmental and societal impact assessment, ADS robustness under adverse conditions and edge cases, public trust and user acceptance, accessibility and inclusion. Other topics include scenario-based testing, public transport integration, business models, infrastructure and V2X readiness, liability and responsibility, operational service feasibility, regulatory approval pathways, and logistics integration.

The report was authored by Mohsen Azarmi, Hakan Yekta Yatbaz and Mehrdad Dianati (Queen’s University Belfast), with review contributions from Satu Innamaa (VTT), Jeroen Hogema (TNO), Marcel Sonntag (RWTH Aachen University) and Henri Sintonen (VTT).
