Let me explain the key differences between route2poly.py and the TraCI-based code I provided:

1. Purpose and Functionality:

• route2poly.py: Creates polygon (polyline) visualizations of routes and saves them to a .poly.xml file. These are static visualizations that show the entire route path at once. It's used to visualize route paths before simulation.
• TraCI code: Dynamically changes edge colors during the simulation runtime. It allows real-time color changes based on conditions while the simulation is running.

2. When to Use Each:

• Use route2poly.py when you want to:

  • Visualize all possible routes in your network
  • Create a static visualization of routes
  • Generate a permanent .poly.xml file for later use

  # Example usage of route2poly.py
  python route2poly.py network.net.xml routes.rou.xml --hue 0.5 --saturation 1
  

• Use TraCI when you want to:

  • Change colors dynamically during simulation
  • Respond to real-time events or conditions
  • Make interactive visualizations

  # Example of TraCI color change
  traci.edge.setColor(edge_id, (255, 0, 0))  # Changes color in real-time
  

3. Color Control:

• route2poly.py:

  • Uses HSV color model (Hue, Saturation, Brightness)
  • Colors are set when generating the polygon file
  • Options like --hue, --saturation, --brightness

• TraCI:

  • Uses RGB color model
  • Colors can be changed at any time during simulation
  • Direct RGB value control (0-255 for each channel)

4. Output:

• route2poly.py creates a .poly.xml file:

<polygons>
    <poly id="route1" color="0.5,1,1" shape="x1,y1 x2,y2..."/>
</polygons>

• TraCI modifies the visualization directly in SUMO-GUI without creating additional files.

Would you like me to show you how to combine both approaches or explain more about either method?
