“…However, in current commercially available car models, V2X functionalities are limited to Level 0 warning signals to the driver. In 2019, the Car2X technology in the new Volkswagen Golf, for example, was rolled out to customers, which was marked as a major technological advancement within the V2X community, a concept shown in Figure 2 [52]. Car2X, a communication system enabling vehicle-to-vehicle and vehicle-to-infrastructure interactions in these models to facilitate real-time information exchange for improved road safety and enhanced traffic efficiency in these models.…”

The significance of V2X (Vehicle-to-Everything) technology in the context of highly automated and autonomous vehicles can hardly be overestimated. While V2X is not considered a standalone technology for achieving high automation, it is recognized as a safety-redundant component in automated driving systems. This article aims to systematically assess the requirements towards V2X input data to highly automated and autonomous systems that can individually, or in combination with other sensors, enable certain levels of autonomy. It addresses the assessment of V2X input data requirements for different levels of autonomy defined by SAE International, regulatory challenges, scalability issues in hybrid environments, and the potential impact of Internet of Things (IoT)-based information in non-automotive technical fields. A method is proposed for assessing the applicability of V2X at various levels of automation based on system complexity. The findings provide valuable insights for the development, deployment and regulation of V2X-enabled automated systems, ultimately contributing to enhanced road safety and efficient mobility.

“…For instance, Mehr & Eskandarian (2021) proposed an onboard system for CVs to guide the lane changing during a freeway incident and showed that the proposed method can reduce travel delays. Farrag et al (2021) proposed a smart TIM system based on CVs and evaluated the performance of traffic safety, traveler mobility and gas emissions. All studies using the lane assignment strategy are simulating a freeway incident.…”

Ephemeral traffic incidents, such as a fallen tree on a road, pose traffic safety hazards, and impact locally on traffic. While these incidents are neither predictable nor persistent, their existence is relevant for all vehicles planning to pass by while the impact continues. This article develops a novel communication strategy for vehicular ad hoc networks aiming to inform all the affected vehicles, while involving only the minimum number of non‐affected vehicles. This strategy exploits time geography as a spatial and temporal filter, ensuring also that the information broadcasting timely terminates when the incident is over. Agent‐based traffic simulations show that, when a road is temporarily blocked due to an ephemeral incident, the proposed decentralized information management model achieves significant improvement in travel efficiency and automatically updates outdated incident information in time.

“…According to some authors [21,[26][27][28], connected and autonomous vehicles (CAVs) can prevent conflicts and decrease fatal accidents by at least 40%. Moreover, CAVs' driving systems are said to be able to adapt as they approach hazardous locations, potentially reducing delays and increasing safety while navigating busy traffic crossings [21,29,30].…”

Evaluating the Impacts of Autonomous Vehicles’ Market Penetration on a Complex Urban Freeway during Autonomous Vehicles’ Transition Period

Autonomous vehicles (AVs) have been a rapidly emerging phenomenon in recent years, with some automated features already available in vehicles. AVs are expected to potentially revolutionize the existing inefficient state of urban transportation and be a step closer to environmental sustainability. This study focuses on simulation modeling in assessing the potential effects of autonomous vehicles (AVs) and on mobility and safety by developing a framework model based on traffic microsimulation for a real network located in Al-Madinah, Saudi Arabia. The market penetration rates (MPRs) will not reach 100% in the near future; instead, penetration will progressively increase. As a result, in our study, we investigated the potential effect of AV technology in five different AV market penetration rates: 0% (baseline), 25%, 50%, 75%, and 100%. The results suggest that Avs significantly improve the network’s safety and operational performance at high penetration rates. Specifically, estimated vehicle delays decreased by 26%, 34.4%, 63.7%, and 74.2% for 25%, 50%, 75%, and 100% AV penetration rates, respectively. Finally, we think this study will help decisionmakers over in the long-term in their attempts to achieve sustainable development through the optimal integration of innovative and novel technologies.
