STNN

This is the PyTorch implementation of paper "Space Meets Time: Local Spacetime Neural Network For Traffic Flow Forecasting".

Installation

pip install -r requirements.txt

Requirements

• pytorch (1.7 or later)
• numpy
• prettytable
• tqdm

Train

Before train, unzip dataset to data/METR-LA, data/PeMS-Bay

# Train on PeMS-Bay
python train.py --data data/PeMS-Bay --t_history 12 --t_pred 12 --keep_ratio 0.2

Test

This single model can be used in both METR-LA and PeMS-Bay traffic prediction

python test.py --data data/METR-LA --model weights/STNN-combined.state.pt
python test.py --data data/PeMS-Bay --model weights/STNN-combined.state.pt
