+# Smart Traffic Lights
+
+## Summary
+
+An optimization simulation where traffic light agents use local information to minimize vehicle wait times at intersections.
+
+![Simulation of Smart Traffic Controller](./assets/chrome-capture-2026-03-09_TrafficModel_Mesa.gif)
+
+## Installation
+
+To install the dependencies use pip and the requirements.txt in this directory. e.g.
+
+```
+    $ pip install -r requirements.txt
+```
+
+
+
+Then open your browser to [http://127.0.0.1:8521/](http://127.0.0.1:8521/), select the model parameters, press Reset, then Start.
+
+## Files
+
+* ``smart_traffic_light/agents.py``: Defines the CarAgent, the TrafficLightAgent and the IntersectionController classes.
+* ``smart_traffic_light/model.py``: Defines the Traffic model and the DataCollector functions.
+* ``run_example.py``: Script to compare waiting time in traffic using smart and normal traffic light controller.
+* ``app.py``: Visualization script on Solara.
