The recent wireless networks use advanced communication technologies to connect numerous elements such as vehicles, pedestrians, infrastructure, highways, etc. The concept of V2X (vehicle-to-everything) communication is introduced as a result of advanced communication technologies. Vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-pedestrian (V2P), and vehicle-to-cloud (V2C) communications are all possible through V2X communications. In a nutshell, V2X provides a platform for intelligent transportation. Road safety (traffic jam/incident reporting, collision warning, and collision avoidance), cooperative autonomous driving (traffic information sharing), entertainment services, and many other use cases are the applications of V2X communications in the context of intelligent transportation systems (ITS). Automobile firms are continuously developing more intelligent vehicles aiming to reliable life of passengers. With various unique technologies and ITS research and development, travel is becoming more efficient and reliable.

Every year, new vehicles are introduced that pay more attention to the safety of passengers and pedestrians. Traffic growth has several negative effects including long delays in mobility, a decline in economic growth, increased fuel expenses, air quality, and public health. Congestion control or avoidance can cope with these conditions and can sustain transportation-related energy. Sustainable mobility can help to mitigate traffic congestion and vehicle emissions, but the use of advanced traffic signal controllers and ITS are increasingly attractive to optimize the performance of existing traffic infrastructure. ITS offers novel traffic management schemes for optimal transport. Many intelligent traffic control methods have made a breakthrough in theory, but most of them are still not mature in practical applications. Therefore, a comprehensive study regarding traffic control on congested roads’ segments is required to explore a new ideology for smart traffic management using V2X communications. An extensive literature survey, comparative studies, user experiences, models/architecture, and experiments/evaluations are required to cope with the existing ITS challenges.
