Hello, without looking at the network file I cannot tell why the junction has so many links. I do agree that it does not match the number of links in the screenshot. Putting all zeros into the response string cause vehicles taking that link to ignore all other traffic when driving onto the junction. If you have a traffic light and if the traffic behaves nicely these response strings could indeed all be zeros. However sometimes vehicles cannot leave the junction because the next lane is already jammed (doesn't look like it in your screenshot though). When this happens other vehicles have to take this into account even if they have priority/green light. This is where 'foes' come into play. When reading request indices note that the rightmost number corresponds to link 0. When "misusing" foes and response you may create collisions but the simulation should run fine apart from that.
