Trajectory Visualizer

A lightweight Matplotlib tool that plots agent trajectories from CSV files — a quick way to sanity-check scenario motion before or after simulation.

Location: tools/trajectory-visualizer/

What it does

Reads every *.csv in a folder, uses the first three columns (by position) as timestamp, pos_x, pos_y, and plots all trajectories in a single figure with a legend.

Requirements

• Python 3.8+
• pandas, matplotlib

pip install pandas matplotlib

Run

cd tools/trajectory-visualizer
python plot_trajectories.py --folder /path/to/csvs

The folder should contain trajectory CSVs whose first three columns are time, x, and y (column names are ignored). Trajectory CSVs of this shape are produced by the traffic simulator.

Sample CSVs not bundled

Sample trajectory CSVs are not included in this repository. Generate your own with the traffic simulator, or export them from a scenario.
