The blog post provides a lot of insights. Good read. Some questions.
Do you plan to support area routing?
And you write: "However, the good news ended there: Openrouteservice does not publish the code for calculating this green index". Is your code publicly available and allows "the news to end good" ;) and maybe even integrated elsewhere?
Good point RE the green index calculation. The very least I could do would be to upstream a reference implementation and documentation back to Openrouteservice. I will take care of that.
