Publication Open Access V2X Messaging with CoAP and EdgeX for Probabilistic Risk-Aware Coordination in Mixed Urban Traffic2025-09-10 - Mendes, Bruno; Araújo, Marco; Goes, Adriano; Corujo, Daniel; Oliveira, Arnaldo S. R.This article presents a standards-based architecture for V2X communication using CoAP and EdgeX Foundry. By mapping ETSI ITS messages to CoAP, the system enables efficient risk alerting at the edge. An inference module illustrates the architecture's extensibility, and the simulation confirms responsiveness and scalability under mixed traffic conditions.Publication Open Access Study of the Impact of Cooperative Maneuvers Among Different Types of Vehicles in Real-World Scenarios2025-08-01 - Mendes, Bruno; Goes, Adriano; Araújo, Marco; Corujo, Daniel; Oliveira, Arnaldo S. R.The automotive sector has seen a significant increase in autonomous mobility expenditures throughout the past decade through private-sector investments made by original equipment manufacturers and public research via universities and institutes. However, despite the significant funds invested in enabling technologies, the world is not much closer to self-driving vehicles on its main roads. One of the reasons for this is the lack of willingness to regulate this sector, as it requires taking accountability for failures. Moreover, to ensure the existence of autonomous vehicles (AV) on the road, regulation must be pushed, ensuring that both non-autonomous and AV can coexist. The lifespan of a vehicle can range from fifteen to thirty years on average. So, considering that classic vehicles still represent almost all vehicle sales, self-driving vehicles will share the roads in the next few decades. This implies that AVs must be able to adapt themselves to the behavior of human drivers and hold mechanisms to handle the higher probability of collisions and jams. Only once this adaptation is proven successful can regulation finally be implemented. This article explores how 5G, V2X, and intelligent transportation systems can make AV decisions safer by mitigating mixed-traffic vulnerabilities through V2V information exchange. Mathematical modeling and simulations such as Markov chains, Bayesian networks, and Monte Carlo simulations were used to quantify impact. Simulations modeled how non-AVs and AVs interact and estimate the probability of accidents and congestion across cooperation levels. Additionally, fleet composition dynamics were analyzed to assess accident rates and traffic flow as AV fleets grow. The results confirm that cooperation is imperative. Cooperative strategies significantly reduce crashes and optimize traffic flow at lower AV adoption. Complete autonomy is a challenging objective to obtain in the near-term future, and, under this study, cooperative integration between non-AVs and AVs must occur in a phased manner.Publication Open Access Edge-Aware Zero-Touch Slice Reconfiguration for Cross-Layer Resource Optimization in 5G Networks2025-12-01 - Barbosa, Raul; Duarte, Paulo; Silva, João; Gameiro, João; Araújo, MarcoModern 5G networks require intelligent, autonomous orchestration to sustain ultra-lowlatency servicesand dynamic workloads.
