Hello - Queue output only ever considers a single lane at a time and therefore should not extend beyond the length of a single lane. (The only exception being a vehicle that has only it's front on the current lane and it's total vehicle length is still counted towards the queue length) - For logging period, see https://github.com/eclipse/sumo/issues/9232 - For logging only the maximum, see https://github.com/eclipse/sumo/issues/9233 (pull requests welcome)
