Hi, I compared another simulation with step length 1 and step length 0.1: <http://sumo-user-mailing-list.90755.n8.nabble.com/file/t300/steplength_comparison.png> The vehicle in the simulation with step length 0.1 can drive while in the step length 1 simulation it has to stand still. For example around 300 samples in the step length 1 simulation compared to arond 3000 samples in the step length 0.1 simulation. So the behaviour is different. https://sumo.dlr.de/docs/Simulation/Safety.html#action_step_length <https://sumo.dlr.de/docs/Simulation/Safety.html#action_step_length> The wiki says the reaction time is set by step time. What I actually wanted was the same simulation with the same behaviour but more frequent output values. -- Sent from: http://sumo-user-mailing-list.90755.n8.nabble.com/
