  • I’d like to provide a bit of information on C-ITS: Next Generation of Intelligent Transportation Systems. One of the most exciting areas these technologies are featured in is the management and optimization of a city’s, state’s, or even country’s transportation systems, collectively known as intelligent transportation systems (ITS). Intelligent transportation systems are becoming more and more widespread and being trialed and implemented in several different parts of the world, this in turn has driven more investment, research, and development of technologies that enhance or expand on ITS architectures. The development of vehicles that are increasingly connected to mobile or wireless networks has also enabled an increase in the applications of these technologies within ITS frameworks.
