Are there any suggestions on how to create on and off ramps for a highway like in a cloverleaf interchange?

Hi !

Did you have a look at the Modern Streets Example you can download from within the CityEngine ?

Help > Download Tutorials and Examples

?

Let me know .. :)

I did review this example after you referenced it.  Perhaps I am missing something, but i did not see anything to help me out there.

Specifically I am looking to have intersection nodes on the graph network that do not create a "street intersection" buy would allow something more like an off and on ramp like accessing or leaving an expressway.  We have roadway courses of traffic lanes merging together in our project. 

Thanks,

Vic

Hi, Victor.

Did you ever resolve this issue? I'm currently looking for answer to this as well.

Hi !

Sorry for the late reply, I've been in holidays.


If you select a street node, you have the option to change the default 'Crossing' connection to a 'Junction' in the Inspector.

Though sadly, the Dynamic City Layout tools currently still are limited. Especially specific On- and Off-Ramp connections are not yet possible to define as precise as you'd need.

We're working on the Street System, but this specific with will take some more time !
