Hello,

I'm searching for the formula for the 2 pictures in attachment.

The first is de reduction factor day and the other is the reduction factor night.

As example for the factor day: on X I put the distance 10 Km, then I choose the value off L = 3

then I have as reduction factor on the Y = 0,3 or 30%

For the reduction factor night it is the same way off working but with other curves.

2. Relevant equations

Can someone help me to find a solution for bothh graphs

3. The attempt at a solution

I don't know how to find a solution.

Thanks for the help.

Axel
