  In recent years, the use of cellular network technologies to provide
communication-based applications to vehicles has received considerable
attention. 3GPP, the standardization body responsible for cellular networks
specifications, is developing technologies to meet the requirements of
vehicular communication applications, and the research community is testing and
validating the ability of those technologies to implement different
applications. This survey presents the body of work dealing with the use of
cellular technologies to implement communication-based applications for the
connected vehicle. We focus on basic and advanced road safety and traffic
efficiency applications, which are critically important for the future of
vehicular networks. We start by describing the different cellular-related
technologies that have a role to play in providing services to the connected
vehicle, propose a classification of types of communication used in vehicular
applications, and then apply this classification to organize and present recent
research work on the topic. Finally, we identify the main challenges in the use
of cellular technologies to develop applications for the connected vehicle.
