Summary
This review paper examines the synergistic relationship between vehicle connectivity and automation, characterizing them as a "sibling relationship" that jointly shapes the future of transportation. The authors aim to clarify how these technologies individually and collectively impact road transportation efficiency and safety, and to identify current and expected future synergies. This analysis is intended to provide knowledge that can justify investments in transportation systems. The paper categorizes the relationship using biological analogies, distinguishing between mutualism (where both technologies promote each other) and commensalism (where one promotes the other without reciprocal benefit). The authors define vehicle connectivity as the capability of vehicles to communicate with external systems (vehicles, infrastructure, pedestrians) via technologies such as DSRC, Cellular-5G, Wi-Fi, and Bluetooth. Automation is defined as the capability of a vehicle to self-navigate using sensors (radar, lidar, GPS) and AI-based control systems, classified into six SAE levels from zero to full automation. The paper reviews existing literature on the benefits of each technology. Connectivity offers safety improvements by reducing driver perception-reaction time and providing awareness beyond onboard sensor ranges, as well as efficiency gains through collaborative routing, speed harmonization, and optimized traffic signal control. Automation reduces driver responsibility and improves operational performance through precise control. The central finding is that the sibling relationship is currently lopsided, resembling commensalism. Vehicle connectivity has immense potential to enhance vehicle automation by providing comprehensive environmental awareness that overcomes the spatial limitations of onboard sensors. Connectivity enables advanced autonomous operations such as truck platooning, fleet management, and cooperative lane-changing maneuvers, significantly improving both individual vehicle performance and system-wide efficiency. Conversely, automation does not significantly promote vehicle connectivity in the short term. While automation may provide a stronger justification for connectivity by demonstrating its value in processing large data streams, it does not directly enhance the ease or smoothness of information flow between connected entities. The significance of this analysis lies in its implications for market adoption and policy. The authors argue that future synergies will be shaped by the relative pace of advancement, regulation, and market adoption of both technologies. In the long term, growing market shares of autonomous vehicles may spur investments in connectivity research and development, potentially leading to economies of scale and reduced costs. The paper concludes that while connectivity is a critical catalyst for advancing automation, the reciprocal benefit is less immediate, suggesting that infrastructure and policy efforts should prioritize connectivity to unlock the full potential of automated vehicles.
Key finding
Vehicle connectivity currently acts as a commensal catalyst that significantly enhances vehicle automation, whereas automation is expected to promote connectivity only in the long term through market adoption and investment incentives.
