Interesting idea...I think you can bring out a good map.
Some comments after a quick look:
Hanged-Hill-Judge-Prison bonus is not clear
Not to mention that it took me hours to find all the judges and the prison
Hill could be coloured with the bonus color instead of the accused (title) color, but it's just a personal preference.
Colors, I got these results using Vischeck (colorblind simulation)
I think that some colors/bonus are hard to distinguish
one last thing, the legend that explains how roads work in the left corner, i think it will look better and clearer in this way:

Looking forward your next update
