Synthetic 10-Hour Traffic Simulations for Central Athens (Base/Rain)

This release provides 8 CSV trace files from 10-hour microscopic traffic simulations of central Athens, generated with the SUMO (Simulation of Urban MObility) toolkit. Two distinct scenarios capture different operating conditions: Base – the unmodified network under typical morning and afternoon peak volumes. Rain – the base network under simulated rainfall, modeled via reduced friction on the network lanes. Each scenario is split into train and test runs. The train set uses one random seed for trip generation and traffic-generation periods, while the test set uses the same seed for trip generation and perturbs the traffic-generation periods by random noise to introduce realistic variability. The two scenarios use a different random seed for trip generation, so we also have some realistic variability between them as well. For each of the two scenarios (base, rain) and each split (train, test), you’ll find two CSV outputs: FCD - floating car data, organized by timestep > vehicle (id, x, y, speed, lane, odometer) Emission - emissions trace, organized by timestep > vehicle (id, fuel, waiting time) The following SUMO tools were used: osmWebWizard - exporting the network from OpenStreetMap. randomTrips - generating the random trips based on traffic generation periods.
