[sumo-user] The benefit of using sub-second StepLength

[Mohsen Rahmati <mohsen.eng74@xxxxxxxxx>]

Hello,

I would be thankful if any one could tell me what are the benefits of using sub-second StepLength?

as stated in SUMO user documentation, for a realictic behavior of drivers reaction time, it is suggested that to use higher value for actionStepLength.

"By default, the action step length is equal to the simulation step length which works well for the default step length of 1s. When performing sub-second simulation by setting a lower step-length value, it may be useful to maintain a higher action step length in order to model reaction times and also in order to reduce computational demand and thus speed up the simulation." ref:wiki/Car-Following-Models

how should i configure StepLength and actionStepLength in order to get an average of 2 second reaction time? 

With Best Regards,
