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

This release provides 3 trace files containing Floating Car Data (FCD) from 10-hour microscopic traffic simulations of central Athens, generated with the SUMO (Simulation of Urban MObility) toolkit. Each simulation reflects distinct conditions and configurations. train-fcd - Training simulation on the base network test-fcd - Test simulation on the base network rain-fcd - Simulation on the rain-modified network (with reduced friction on all lanes) These files are now available in both CSV and Parquet format. The output is organized by timestep and for each vehicle that is in the simulation at that timestep a row of its id, x, y, speed, lane, odometer, fuel, and waiting is logged. Each simulation has a duration of 10 hours, spanning from morning to afternoon. There is a traffic pattern applied, with morning and afternoon peaks and lower mid-day activity. This traffic pattern is described by a list of per-hour traffic generation periods. On that list, some noise is added for each simulation, using a different random seed for each one. The same random seed is also used together with the traffic generation periods to generate the random trips used for each simulation. The goal was to introduce realistic variability, without going completely off a common traffic pattern. For the generation of this synthetic dataset, the following tools were used. osmGet – Extract OpenStreetMap data from a bounding box over central Athens osmBuild – Convert OSM data into a SUMO-compatible network randomTrips – Generate random trips based on per-hour traffic generation periods sumo – Run the microscopic simulation and export FCD data
