<p>This study focuses on the innovative design of a high-voltage speed bump that captures kinetic energy from vehicles, addressing the significant need for sustainable energy solutions in transportation systems. The increasing demand for energy-efficient infrastructure makes this research particularly relevant, as it explores a method to power traffic facilities and wireless sensors, contributing to intelligent transportation systems. To achieve this, we developed a novel device that integrates a speed bump, suspension system, and generator, effectively converting the kinetic energy of passing vehicles into electrical power. The design was modeled using SOLIDWORKS, and simulations were conducted in MATLAB with Simulink to optimize energy production and vehicle comfort. The results demonstrate a peak power output of 2400 watts and a maximum damping force of 14000 newtons, indicating the system’s robust performance. Efficiency analyses revealed a peak efficiency of 88.2 % and an average efficiency of 35.6 %, showcasing the system’s capability to harness energy effectively under varying conditions. These findings suggest that the proposed speed bump design not only enhances road safety but also offers a viable solution for sustainable energy generation in high-traffic areas. The novelty of this work lies in its dual crank-shaft mechanism, which allows for energy capture in both directions, surpassing previous designs in the literature that typically focus on unidirectional energy harvesting. This research paves the way for integrating energy-harvesting speed bumps into urban infrastructure, promoting environmental sustainability and reducing electricity costs.</p>
