Thank you so much for taking the time to assist me @karussell!
I’m invoking from Java and I was following this post Avoiding road classes and environments - #14 by diego-peteiro
I had read the post you mention before but I think my main issue is on how to use those JSON configurations from Java. Also, it seems like I can’t use the init() method with the params to load the toll road information and at the same time set a CustomProfile with the Statement expressions… 
This is where I’m stuck 
Any help with an update of the Java codein this blog post would be deeply appreciated… Avoiding road classes and environments - #14 by diego-peteiro
