Digitalization of the services in energy, healthcare, transportation, education, and many other domains brings a new dimension to urban life, paving the way for the creation of smart cities that are more connected than ever. While the rapid advancements in information and communication technologies help drive this new trend forward, they also create new challenges due to the increasing complexity and dynamics in the smart city service ecosystem. Service providers who want to establish cross-domain services are confronted with the requirement of interconnecting a fast-growing and diverse set of technologies.

Future urban mobility solutions, in particular, connected and automated mobility (CAM), can significantly benefit from the smart city infrastructure and services for lighting, parking, electric vehicle charging network, etc. Smart city concepts can also be used to better coordinate urban mobility, which is becoming increasingly multimodal, at both micro and macro levels. On the other hand, intelligent vehicles and CAM infrastructure, with a multitude of sensors such as LIDAR, cameras, and road-side units (RSUs), can serve as extensions of the smart city infrastructure and enable new services or offer service improvements.

The large body of existing work under the themes of the Internet of things (IoT) and wireless sensors networks (WSNs) sets a good baseline for the consolidated organization of future mobility services in emerging smart cities. Nevertheless, this needs to be revisited in light of the new challenges of the high diversity and dynamics of connected mobility entities in smart cities. The realization of many of the scenarios in this context also requires novel multilayer and cross-domain approaches.

This Special Issue aims to gather recent research findings and technology developments toward the conceptualization and realization of future mobility systems in the smart city context. We invite contributions on a broad range of topics, from the networking and processing of sensor data to the novel architectures and applications related to smart cities and future mobility. Articles that present theoretical aspects, practical developments, new technologies, experimental results, or a tutorial-style review of the literature with new perspectives are all welcome.

Particular topics of interest include, but are not limited to:
- Novel IoT and WSN architectures for the scalable integration of future vehicles with the infrastructure and services of smart cities;
- Distributed AI and machine learning applications for future mobility in smart cities;
- Novel use cases and applications for intelligent transport and logistics in smart cities;
- Digital infrastructure and vehicular connectivity through 5G, C-V2X, and ITS-G5 technologies in smart cities;
- Integrated networking and computing solutions for the intelligent mobile–edge–cloud continuum;
- Intermodal mobility services in smart cities;
- Energy informatics for fully electric mobility in smart cities;
- Security and privacy issues in urban mobility systems and digital cities;
