The increasing number of personal and commercial vehicles in transit induces a high volume of road traffic, which can often lead to serious incidents such as permanent traffic jams, increased gas pollution, accidents with material or even human losses. Technology and transportation infrastructure providers are required to provide safer, more scalable, flexible, and cost effective solutions to these problems. Intelligent Transportation Systems (ITS) have been developed to meet these requests, by offering traffic monitoring, guidance or alerting communication capabilities to or between vehicles, or intelligent infrastructure safety elements. This paper investigates the possibility of using common hardware such as a smart phone to achieve V2V or V2I communication, as a solution to implement offline alerting capabilities in Intelligent System for Vehicle Navigation Assistance (SIAN) research project.
