Abstract The paper presents an overview of the evolution of research in the field of communications for ITS (Intelligent Transportation Systems). After a brief description of the services aimed at improving safety and efficiency of road transport, a synthetic view of the past and current research activities is presented and the role of communication‐based systems for ITS service provision is discussed. Several examples of dedicated systems currently studied are presented, afterwards the attention is focused on the assessment of existing relevant standards in mobile communications to define and activate new ITS services. As far as dedicated solutions are concerned, the paper shows some results related to radars as well as 60 GHz and infrared communication systems. An example of ITS service provision by means of an already standardized system is given evaluating the feasibility of an Emergence Warning service based on GPRS (General Packet Radio Service); furthermore the performance of road‐to‐vehicle and target‐to‐vehicle communication, based on Bluetooth, is addressed by means of both an analytical and experimental approach.
