hey really good work, im doing something similar for walkability radii have you done anything on those lines?

Hi Benjamin! In the model I consider the stops closer than 350 meter in each cell (I use ShortestWalk component). I know how many lines (and which ones) pass in each stop, then calculate the level of accessibility with a function that considers the inverse of the distance (1/d) and the number of lines.

So you can see in light green most served cell and in black the less ones. The pink circles are the bus stops (radius is function of number of lines), the red one is the best cell, the violet ones are the worst.

Using an excel VBA form I can interact with the model switching on/off single or multiple lines and other modality (Subway lines and Urban Train), and set the maximum value for gradient (that means that light green cells have at least this value).

This is really interesting work. I think it is hard for most people to understand, but if you explained it in more detail, more people would be able to appreciate what you've done.
