Issues related to braking and acceleration in vehicles represent both technical and environmental challenges, regard less of the type of drive, whether combustion or electric. In conventional vehicles, the emission of particulate matter is a problem associated with the friction between brake pads and discs, leading to air pollution and health hazards. Brake dust contributes to up to 55% of particulate matter in urban environments. In electric vehicles, the processes of braking and rapid acceleration affect battery wear; however, thanks to energy recovery technology, it is possible to recuperate up to 70% of the kinetic energy. This paper proposes a solution involving the placement of induction loops before intersections with traffic lights to enable the recovery and storage of energy, which could be used to power vehicles waiting at intersections, as well as placement behind intersections to supply power to vehicles accelerating when leaving the intersection. The study considers the application of various energy storage technologies, such as flow batteries, supercapacitors, and flywheels. Each of these technologies offers unique benefits and limitations, such as long operational life, a high number of charge/discharge cycles, and environmental friendliness. Simulations per formed using AIMSUN. Next software made it possible to analyze energy consumption and pollutant emissions in various scenarios, indicating the potential benefits of traffic optimization, the use of electric vehicles, and energy recov ery. The research results highlight the importance of traffic smoothness and the use of energy storage technologies to reduce pollutant emissions (possible reduction: CO2 by over 40%, NOx by 48%, PM by 73%, and VOC by 40%) and energy consumption (lack of smooth traffic flow leads to approximately 159% higher energy use). The proposed use of energy storage technologies at intersections may significantly decrease particulate and carbon dioxide emissions. The final choice of energy storage technology will depend on local conditions, such as space availability, investment costs, and market availability.
