This is what I have been working on. It is a 2 and a half dimensional paper map of Tolworth roundabout. I originally started making it for us to understand the structure of this roundabout.
The roads cross over each other and the underground pedestrian passages are actually connected as they are in real.
A thought came to me that what I'm troubled most about intersections is that I get confused how to get where I want to go (like the one around imax theatre in Waterloo!). So, I think there should be easy-to-understand maps for the pedestrians around the roundabout. Not getting lost will also contribute to the safety there.
I will continue working on making a map(maps).
