Connected vehicles are expected to be a pillar of a smart society and to revolutionize the way people move. The use of wireless communication technologies integrated on board (or in the driver's or passengers' pockets) is the key to connecting vehicles, infrastructures, and travellers. The widespread use of connected vehicles generates high volumes of transportation-related data, enabling plenty of new applications which, according to Cisco visual networking index, will give a boost to the

Connected vehicles will improve safety, traffic management, and urban and suburban mobility and will enhance the development of new services like accident prevention, Internet access, Internet backbone, ride-sharing, vehicular social networking, environment monitoring, infotainment, usagebased insurance, preemptive maintenance, and many more. This phenomenon is fostering an acceleration of standardization efforts to define new architectures and requirements for the various emerging vehicular applications scenarios. In addition to well established vehicular communication standards, that is, the IEEE WAVE/802.11p in US and the ETSI ITS G5 in Europe, different working groups within 3GPP have recently completed a set of cellular vehicle-to-anything (V2X) features as part of the LTE-Advanced suite of specifications, and studies on future 5G systems will take these concepts even further by evaluating how cellular communications together with emerging access technologies-such as visible light and mm-waves-can play a key role in enhancing the on-board intelligence of future vehicles. This special issue focuses on connected vehicle-driven applications and aims at covering cutting-edge research advances in topics covering standardization, wireless communication technologies challenges, field trials, and tight interworking between on-board vehicle intelligence and wireless communication standards. A general view on architectures and technologies for connecting vehicles is provided in the following survey by the Guest Editors themselves: "A Survey on Infrastructure-Based Vehicular Networks" by C. M. Silva et al. The paper presents an in-depth survey of more than ten years of research on infrastructures, wireless access technologies, and deployment. In fact, even if direct vehicle-to-vehicle communications will allow new challenging applications, the infrastructure still represents the key to let vehicular connectivity available and suitable also nowadays. The paper also identifies the limitations of present technologies and infrastructures and the challenges associated with such infrastructure-based vehicular communications, also highlighting potential solutions.
