Making roads more organic

A friend told me every day that the pattern of the minor roads where too much right angled. I used to say "don't worry, it's only a graph matter and I can change it in fives minutes". But will it be that simple?

Five minutes later :

With this procedural architecture, I can work on any stage of the generation proccess, all changes cross the generation layers and give results as well. The tool seem to be very power full and any road pattern can be randomly computed without causing any exception.
