Every industry, including academia and business, has seen a major change as a result of technological advancement. In the last two decades, smart transportation has gained a lot of popularity and is now seen as a crucial component of the automotive industry. Driverless cars, autonomous vehicles, and electric vehicles are all becoming a reality these days. When it comes to road transportation, the term “smart transportation” refers to vehicular ad hoc network (VANET). A lot of the work is still only in research articles and has not yet been applied practically. When discussing VANET, the primary issue is for road user safety. Mobile vehicle intercommunication and intelligent infrastructure are used to transmit emergency information among network nodes for quick and effective decision-making. This article provides an overview of VANET, its characteristics, and application areas. Afterward paper discusses various challenges in VANET and analyzes the future scope of VANETs. In end, paper discusses some of the very popular simulators used for VANETs simulation. This survey article that covers issues, challenges, and applications of VANET can benefit society by promoting the development and deployment of VANETs, which can improve road safety, enhance transportation services, and provide economic benefits.
