Nonequilibrium steady states, from planetary dynamics to biological processes, constantly dissipate energy to their environment, producing entropy at a constant rate. Quantifying this dissipation is key to understanding how far systems operate from equilibrium but remains experimentally challenging. I will present a new approach to infer entropy production directly from trajectory data, using measurable kinetic quantities known as traffic and inflow rate, without requiring knowledge of microscopic forces or fluxes. The method remains effective even under partial observation, providing a practical framework to quantify nonequilibrium behaviour in complex physical and biological systems.
