Cultural Stages for Traveller

I made a chart a while back similar to the Kardashev scale to show cultural stages. I would think that TAS would provide something like this for a culture. And this would be used by Travellers more than Tech Levels would be. Stage 0 and I would be Amber Travel Zones and Stage II would automatically be a Red Zone. Then Stage III could possibly be an Amber Zone again...

Stage 0 - pre-sentient
Gorillas, Orangutans

Stage I - Primitive (TL 0-2)
Cro-Magnon, Neanderthal, Dolphin?, Chimpanzees?

Stage II - Planetary (TL 3-5)
The British Empire, Whales?

Stage III - Stellar (TL 6-8)

Current stage of Earth - early stellar

Stage IV - Interstellar (TL 9-15)
The Third Imperium, Hive Federation, Aslan Hierate, The Two Thousand Worlds, Vargr Extents, Zhodani Consulate

Stage V - Galactic (TL 16-20)
