Summary

This review paper examines the current state, synergies, and challenges of three major innovations in highway-oriented surface transportation: automation, connectivity, and electrification. Motivated by the adverse impacts of traditional motorization—such as road crashes, economic loss, and climate change—the authors analyze how these technologies promise to enhance safety, efficiency, and environmental sustainability. The paper synthesizes existing literature, market data, and technological definitions to evaluate the deployment trends, benefits, pitfalls, and barriers associated with these innovations. The authors define automation using the Society of Automotive Engineers’ levels 0–5, ranging from no automation to full driving autonomy. Connectivity is described as data exchange between vehicles, infrastructure, and other entities via technologies like DSRC and cellular networks, categorized into connected human-driven vehicles and connected automated vehicles. Electrification focuses on the resurgence of electric vehicles (EVs) driven by battery advancements and environmental concerns. The paper reviews market trends, noting that while Level 0 vehicles currently dominate, Levels 1–2 are growing, with Levels 3–4 expected to reach 10–20% penetration by 2030. Connected vehicle adoption is projected to triple in the US by 2023, while EV sales surged 89% in 2021, though they still constitute only about 3% of the vehicle stock. Key findings highlight significant promises: automation aims to eliminate human error, the leading cause of crashes, potentially achieving a “zero-death” goal and altering land use by reducing parking needs. Connectivity improves safety and traffic flow through real-time hazard alerts and signal optimization. Electrification reduces carbon footprints and maintenance costs. However, substantial pitfalls exist. Automation faces ethical dilemmas, cybersecurity risks, and potential job losses for drivers. Connectivity suffers from inconsistent protocols and privacy concerns. EVs are hindered by range anxiety, charging infrastructure deficits, battery weight, and grid destabilization risks. The authors emphasize that synergies among these technologies—such as connectivity enhancing AV sensor ranges and automation improving EV economics—can amplify benefits, particularly when technologies reach maturity. The significance of this work lies in its holistic assessment of the barriers to deployment, which include high capital costs, public distrust, and inadequate infrastructure. The authors conclude that realizing the benefits of these innovations requires coordinated legislative policies, workforce training, and infrastructure investment. They warn that supply chain vulnerabilities, particularly regarding lithium mining for batteries, pose long-term risks. Ultimately, the paper suggests that while these technologies will not immediately replace traditional fleets, their gradual integration will radically reshape urban landscapes, commuting patterns, and transportation systems over the coming decades.

Key finding

The synergistic deployment of automation, connectivity, and electrification promises significant safety and environmental benefits but faces substantial deployment barriers including infrastructure inadequacy, regulatory inconsistencies, and public trust issues.
