Support of Safety Services through Vehicular Communications: The Intersection Collision Avoidance Use Case. In : 2018 International Conference of Electrical and Electronic Technologies for Automotive, pp. 1-6.978-8-8872-3738-2 (Electronic)978-88-87237-39-9 (USB)978-1-5386-5144-5 (PoD)https://hdl.handle.net/10016/28221Cooperative systems are based on the periodical exchange of standardized information, thanks to which vehicles can advertise their presence, position and the direction they are moving to, and execute sophisticated C-ITS applications that can detect potentially dangerous situations and properly react. The technological pillar, which must enable a Vehicular ad Hoc Network (VANET), is now being debated: the candidates are the traditional WiFi-based approach and the upcoming cellular one. The application effectiveness, however, depends not only on the technology, but also on how fast it is adopted and becomes widespread, i.e., the so-called technology Penetration Rate (PR). In this paper, simulation is used to evaluate the Intersection Collision Avoidance (ICA) application for both candidate technologies, and evaluated as a function of the technology PR.7application/pdfeng© 2018 IEEEVehicular Networks802.11pLTE-V2V CommunicationsAutomotive safety servicesICA Applicationconference paperTelecomunicacioneshttps://www.doi.org/10.23919/EETA.2018.8493191open access16International Conference of Electrical and Electronic Technologies for Automotive
