Junctions problem with connection ramp

[Beka_Tchigladze]

Hello 

So as you see on the picture below, I am trying to connect 2 lane ramp with 4 lane highway. It is easy and works properly but, after 300m I have exited from highway and adding one lane ramp so it is problem, I have acceleration lane(widening) 300 m and after exit. when I try to connect exit lane there is problem, as you see I have 4 lanes through the acceleration lane and after it became 3 and I want to get 2 lanes after the last exit but it doesn't want to connect properly and there is a mess and also there is not proper striping on the lane even in the beginning of weaving section.

first I got widening but after I had a problem to add several connections on one intersection and use just lane on weaving area.

These can be difficult, but the key is finding the right beginning and ending points for the lane components. Here's the breakdown:

1. Before the on-ramp, you'll have three lane components on the main roadway.
2. Add a fourth lane component that starts in the intersection for the on-ramp. It will be trial-and-error to find the correct place to start it, but when it is done properly, the intersection object will handle the transition nicely.
3. End the third and fourth lane components in the intersection for the off-ramp. Again, it will be trial-and-error to find the right spot, but then the intersection will do the transitioning. It looks like you were trying to use the "transition out" toggles for the lane components. Turn those off and just have an abrupt end.
4. After the off-ramp, there will only be two lane components on the main roadway.

It's a little confusing, so here's a screencast that shows the setup.

You know what? I created new drawings and everything works perfectly but in this model, it does not want to make a proper connection and I do not know why I tried 100 times but it does not work in another model it works well do you have any idea why? everything is the same I just Duplicate the model and built new road I wonder what can be cause this problem?

New project file !!!!

Hmm I'm not sure, my only thought would be that maybe the end of the curve is too close to the intersection? It looks like in the first image that the tangent lengths are longer.

Hello once again so I found out that if the connection is right of my road direction it works properly and if it is left it does not has anyone any idea? here is the video below.

That's interesting, I'm seeing the same thing. I think this is probably an issue with the built-in directionality of component roads.
