Evaluation and Comparison of CO2 and Fuel Consumption for Different Car Following Models

Vehicular communication systems are computer networks in which vehicles and RoadSide Units (RSUs) are the communicating nodes, providing each other with information, such as safety warnings and traffic information. Despite the advanced development in self-driving technologies, intervehicular communication is still an emerging field, with different applications, such as, platooning, road safety and so on. Platooning is an application where vehicles create a formation and travel together and other vehicles follow a physical leader (front car) or a virtual leader, depending on the implementation. Energy saving, labor saving and improvement of safety are expected outcomes of this technology. In this work, a comprehensive simulation called VENTOS is used to evaluate and compare ACC, Krauss and CACC car following models. The results show that, the following cars that use CACC have a better efficiency regarding CO2 emission and fuel consumption.
