Generating Trafficflows with GH

Hello GH Community,
I am a traffic engeneer and I am doing a lot of traffic surveys based on AI software tools. I am using rhino for my designs and constructions for decades.
It would be awsome to have a grasshopper tool to generate traffice flows based on the reults of my surveys and do nice visualisations.
can anyone help me out with this topic? i attached a reference of a basic traffice flow diagramm.

could be done as a freelancer work. budget for the project can be discussed!

all the best,
gerhard
