How to design multi level highway intersection

Question

So I am trying to design a multi-level highway system with the Road Traffic library in Anylogic. The highways have multiple levels and I am having trouble with depicting the difference in the levels of the roads in my model. I looked at the help content related to RTL specifically Library Reference Guides and Tutorials but they don't mention adding grades/inclination to a road to get a multi level system.

I apologize in advance if I missed documentation related to this. But I would like to know how to do this in Anylogic.

Also, there is a Highway Junction model available in the sample models that comes with the installation and implements an increase in the z-value of the roads but I am not sure how to do that when designing the road.

Answer 1

When You draw road Object in RTL, in points section of the drawn road properties panel, you can set the Z value of each point of your road. So you should use more than two points to draw your road, even if it is a straight one. This way you can easily set z value of different points of your road, and build up needed levels, grades or slope of the road.

Hope this helps you.
