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!
