Question about meaning of phase_occ #1

Closed BackMountainDevil closed 2 months ago

BackMountainDevil commented 3 months ago

phase_occ is used in LLM-Assisted-Light/ConventionalMethods/sotl.py. Is it meaning the length of the cars in the same lane?

Hello,

Thank you for reaching out and for your interest in the LLM-Assisted-Light project.

In the context of sotl.py, the term phase_occ stands for "phase occupancy." It is a metric used to calculate the occupancy rate of a given phase at an intersection. Essentially, if phase 1 consists of traffic movements 1 and 5, the occupancy for phase 1 would be the average occupancy of those two movements.

The signal control logic in the script uses phase_occ to prioritize phases. The phase with the higher occupancy is given precedence, allowing that phase to pass first in order to optimize traffic flow.

I hope this clarifies your question. If you have any further inquiries or need additional information, please feel free to ask.

Best regards,
