Adapted Speed System in a Road Bend Situation in VANET Environment

Today, road safety remains a serious concern for governments around the world. In fact, approximately 1.35 million people die and 2–50 million are injured on public roads worldwide each year. Straight bends in road traffic are the main cause of many road accidents, and excessive and inappropriate speed in this very critical area can cause drivers to lose their vehicle stability. For these reasons, new solutions must be considered to stop this disaster and save lives. Therefore, it is necessary to study this topic very carefully and use new technologies such as Vehicle Ad Hoc Networks (VANET), Internet of Things (IoT), Multi-Agent Systems (MAS) and Embedded Systems to create a new system to serve the purpose. Therefore, the efficient and intelligent operation of the VANET network can avoid such problems as it provides drivers with the necessary real-time traffic data. Thus, drivers are able to drive their vehicles under correct and realistic conditions. In this document, we propose a speed adaptation scheme for winding road situations. Our proposed scheme is based on MAS technology, the main goal of which is to provide drivers with the information they need to calculate the speed limit they must not exceed in order to maintain balance in dangerous areas, especially in curves. The proposed scheme provides flexibility, adaptability, and maintainability for traffic information, taking into account the state of infrastructure and metering conditions of the road, as well as the characteristics and behavior of vehicles.
