The aim of the study was to investigate the capability of commercial mobile networks to implement Cooperative Intelligent Transport Systems (C-ITS) services. The research report is divided into four main parts: (i) defining key performance metrics and a service level framework for C-ITS services, (ii) developing a measurement method framework, (iii) assessing the current state, and (iv) recognising development paths for C-ITS deployment. The research methods included a literature review, interviews, a workshop session, utilisation of mobile network coverage predictions and field measurement data, expert knowledge, and collaboration within the project steering group.
