Sommario:
- <p>This release provides 18 CSV trace files from 10-hour microscopic traffic simulations of central Athens, generated with the <strong>SUMO </strong>(Simulation of Urban MObility) toolkit. Three distinct scenarios capture different operating conditions:</p> <ol> <li> <p><strong>Base</strong> – the unmodified network under typical morning and afternoon peak volumes.</p> </li> <li> <p><strong>Closure</strong> – the same base network with lane closures on key central streets to emulate construction or incidents.</p> </li> <li> <p><strong>Rain</strong> – the base network under simulated rainfall, modeled via reduced free-flow speeds, increased following gaps and more.</p> </li> </ol> <p>Each scenario is split into <strong>train</strong> and <strong>test</strong> runs: the train set uses one random seed for trip generation and baseline traffic-generation periods, while the test set uses a different seed and perturbs the per-period volumes by random noise to introduce realistic variability.</p> <p>For each of the three scenarios (<strong>base</strong>, <strong>closure</strong>, <strong>rain</strong>) and each split (<strong>train</strong>, <strong>test</strong>), you’ll find three CSV outputs:</p> <ul> <li><strong>Dump</strong> - a full state dump, organized by timestep > edge > lane > vehicle (id, position, speed)</li> <li><strong>FCD</strong> - floating car data, organized by timestep > vehicle (id, x, y, speed, acceleration, odometer)</li> <li><strong>Emission</strong> - emissions trace, organized by timestep > vehicle (id, fuel, waiting time)</li> </ul> <p>The following SUMO tools were used:</p> <ul> <li><strong>osmWebWizard</strong> - exporting the network from OpenStreetMap.</li> <li><strong>netedit</strong> - selecting the road closures.</li> <li><strong>randomTrips</strong> - generating the random trips based on traffic generation periods.</li> <li><strong>duarouter</strong> - routing a few fixed routes that were added on each test set for later visualizations.</li> </ul>
