Next-generation telematics solutions are driven by the mature and recently employed intelligent transportation systems (ITSs), which are assisted by integration and rapid collaboration with information communication technology (ICT) markets as well as the automotive industry. ITSs are a rising technology and include many aspects. For ITSs, smart vehicles and wireless communications are promising technologies that may improve driving safety, reduce traffic congestion, and support information services in vehicles; further, green life for a blue planet is our ultimate goal. Despite the recent global economic downturn that has negatively affected the automobile industry, active research continues in these areas, and new technical challenges have emerged that demand research and development. Dedicated short-range communication (DSRC) exemplifies these challenges because wireless communication techniques have become significant and relevant for vehicular environments. The direct link between clean mobility and ITSs includes less gasoline consumption and toxic gas emission. Thus, to maximize ITS efficiency, the population that adopts ITSs for daily transportation should increase as much as possible. To achieve this goal, the ITS design should not be limited by technique; the "user-centric" notion is the most important requirement and should be considered.
