Using vehicles as sensors for traffic and environment monitoring is a new paradigm that opens the way to worthwhile applications. Data collected on board are usually delivered through the cellular network, with the consequent overloading risk. This paper focuses on the alternative adoption of short range vehicle-to-vehicle (V2V) and vehicle-to-roadside (V2R) communications, with particular reference...
Collision Avoidance has received serious attention in the automotive research area. There are two methodologies for collision avoidance systems: Sensor-based and ITS-based. The main goal of this work is to provide a comprehensive review of both sensor-based and ITS-based collision avoidance systems. A comparative analysis between these two methodologies and a description of possible future research...
Considering vehicles as sensors for traffic and pollution information is a new paradigm to monitor the environment and to open the way to an efficient smart navigation. In this work we focus on the uplink acquisition of traffic information from vehicles toward a remote control center. With the increase in the number of vehicles equipped with on board units (OBUs) enabling cellular transmissions, this...
Intelligent transportation systems (ITS) make use of wireless communication technologies to provide traffic efficiency and road safety without altering the existing road infrastructure. To really impact on traffic management, ITS should act in real-time, requiring updated traffic information; hence, the collection of small amounts of information frequently transmitted from a high number of vehicles...
