Service Integration Guide

Architecture

RL Service (8000) + LSTM Service (8001) work together for traffic optimization.

Testing

Run the integration test:

python lstm-predictor-service/test_rl_integration.py

API Endpoints

RL Service

POST /predict_action

Get signal phase

POST /reset_hidden

Reset hidden states

GET /health

Health check

LSTM Service

POST /predict

Density prediction

POST /predict-batch

Batch predictions

GET /health

Health check

Configuration

See .env.example in each service directory.
