This video is showing how we can create a continuous terrain that features realistic roads. In that workflow we can even cut roads into steep terrains and create serpentines and mountain streets.
In the second part we then make use of the hybrid topology to texture the terrain, animate objects, place fencing and further refine the model: https://youtu.be/0B1rHBPFMv8
If you want to see another road-terrain approach (2011, but still valid !!! ), you can compare here: https://www.youtube.com/watch?v=Z32jPfsrk9I
If you want to create a parametric terrain, look here: https://www.youtube.com/watch?v=DCNQ3zZuD98
