Intelligent Transportation Systems (ITS) integrate advanced information, communication, and sensing technologies to enhance safety, efficiency, and environmental sustainability. Moving beyond conventional applications such as electronic tolling and adaptive signaling, future mobility envisions a user-centered, cyber-physical ecosystem that dynamically manages demand and supply through decentralized, data-driven approaches. This monograph explores emerging dimensions of intelligent transportation, including biofuel-powered vehicles, smart traffic and rail systems, energy-efficient technologies, multimodal integration, supply chain finance, environmental management, autonomous mobility, and sustainable maritime transport. It aims to equip researchers and practitioners with the knowledge required to navigate and contribute to this transformative transportation revolution.
