# Evaluating the Feasibility of Intelligent Blind Road Junction V2I Deployments
###### Abstract  
Cellular Vehicle-to-Everything (C-V2X) communications is a technology that enables intelligent vehicles to exchange information and thus coordinate with other vehicles, road users, and infrastructure. However, despite advancements in cellular technology for V2X applications, significant challenges remain regarding the ability of the system to meet stringent Quality-of-Service (QoS) requirements when deployed at scale. Thus, smaller-scale V2X use case deployments may embody a necessary stepping stone to address these challenges. This work assesses network architectures for an Intelligent Perception System (IPS) blind road junction or blind corner scenarios. Measurements were collected using a private 5G NR network with Sub-6 GHz and mmWave connectivity, evaluating the feasibility and trade-offs of IPS network configurations. The results demonstrate the feasibility of the IPS as a V2X application, with implementation considerations based on deployment and maintenance costs. If computation resources are co-located with the sensors, sufficient performance is achieved. However, if the computational burden is instead placed upon the intelligent vehicle, it is questionable as to whether an IPS is achievable or not. Much depends on image quality, latency, and system performance requirements. V2X; V2X communications; Vehicle-to-Everything; ITS; cellular; C-V2X; 5G NR; latency; V2I; network planning +

Thus, in a broad sense, Vehicle-to-Everything (V2X) communications describe a framework that enables a connected intelligent vehicle (CIV) to exchange information with fellow road users and stakeholders in automotive environments. As such, the primary objective of V2X communications systems is to enhance road safety and optimise traffic flow by enabling effective communication and coordination among stakeholders within a road traffic ecosystem. Incorporating V2X communications introduces a diverse array of potential scenarios and applications, encompassing safety and traffic efficiency and extending to infotainment and eCommerce uses [8, 9]. Consequently, these potential applications involve a considerable number and variety of stakeholders, necessitating a robust, secure, and reliable wireless communication technology as the underlying foundation. Cellular communications, fostered by the efforts of 3 GPP [10], has long been under consideration as a prospective technology for V2X communications [11]. Within the domain of V2X communications, cellular communications are commonly denoted as C-V2X. The extensive global deployment of cellular base stations establishes a strong foundation for C-V2X to cater to a diverse range of users, including vehicles, trains, cyclists, pedestrians, and stationary infrastructure, thus resulting in the inclination towards leveraging cellular as a viable V2X access technology. The 3 GPP has formulated multiple specifications for C-V2X, where the initial specification emerged as a part of 3 GPP Release 14 [12] in 2017, often referred to as LTE-V2X due to its basis in the 4 th generation of cellular, 4G LTE. Subsequently, another specification was introduced with the advent of the fifth generation of cellular technology (5G NR) in 3 GPP Release 15 [13] in 2019, commonly recognised as NR-V2X. Numerous works have studied the efficacy of both LTE-V2X and NR-V2X for various V2X communications use cases and applications.
