If you want to model zipper merging, set the junction type to "zipper". The color of your connection arrows indicates that the junction is of type "priority".

You'll know that you have it set up correctly if the color of the connections changes to a light brown color.

There is a connection. Its color is grey and hard to see

cannot see a connection from the ramp to any lane of the freeway

Hi barthauer,

Thanks a lot for the suggestion! I have updated to 1.15.0 and the problem still exists.

see below screenshot: the ramp (the arrows) vehicles cannot move, even if 4 out of 5 freeway lanes are closed.

Did I do something stupid to the connection?

Hi,

 

if there is no major reason for keeping the old SUMO version, could you please update to SUMO 1.15 to check if your problem persists? It could be a bug which had been solved in the meantime.

 

Best regards

Mirko

Hi sumo developers:

 

I'm using sumo 1.6.0 and have a common problem with merging.

 

Say I have a freeway (5 lanes) and a on-ramp (1 lane) that merge to the freeway's right most lane

 

the merging type (junction type) is zipper

 

The vehicles on the ramp, however, cannot drive through the junction and wait infinitely, because there are vehicles on the other freeway lanes. Those freeway vehicles don't need to be on the right most lane.. Any vehicle on any of the 5 lanes will block the ramp vehicles.

 

An experiment I did is I closed the right-most lane of the freeway, using sumo-gui. The issue persists.

 

Any ideas to solve this behavior?

 

Thanks a lot!
