- Applications performance analysis in C-ITSPublication . Sandu, Petru Lucian; Simão, José Manuel de Campos Lages Garcia; Serrador, António João NunesAbstract The rapid advancement of transport technology has enabled the deployment of Cooperative Intelligent Transport Systems (C-ITS), enhancing road safety, traffic flow, and overall efficiency. However, current implementations are designed for vehicles with dedicated On-Board Units (OBUs), limiting access for legacy vehicles. This presents a major barrier to widespread adoption and the full potential of C-ITS. This thesis evaluates the C-ITS architecture currently under development by Infraestruturas de Portugal (IP), focusing on its performance, scalability, and ability to support broader adoption. A mobile application was implemented to simulate the end-user experience, subscribing to C-ITS topics through MQTT and enabling practical assessment of message delivery to devices beyond dedicated OBUs. Comprehensive performance tests were conducted, including latency analysis, load testing, and resilience under component failures. This research contributes to the documentation and evaluation of a real-world C-ITS deployment, highlighting key areas for optimisation. Ultimately, it supports the ongoing efforts to scale C-ITS and ensure more inclusive access to traffic information for all vehicles.
