Hi Michael, Thank you very much for the reply. Now I understand the reason why the vehicles disappear. I did as you mentioned, and it works fine. But I have another question now.
What I did was add basically adding two edges. First edge contains two lanes ( index 0, 1). Then at the node with which that edge ends the next edge with a single lane (index 0) begins ( Please correct me if this is not what you advised). Once the network is built, the default behavior is, physically lane 1 of the first edge is straightly linked with lane 0, and lane 0 of the first edge is merged and ended at the node. Can I change this behavior to have this in other way around (i.e. lane 0 of the first edge is straightly linked with lane 0, and lane 1 of the first edge is merged and ended at the node) ? I know that vehicle flow can be changed by altering the connections. I am asking to change both geometry and vehicle flow together. Thanks, Dee.
