No. That is a misunderstanding. The stoppingThreshold has no influence on vehicle behavior. It simply determines whether charging takes place at chargingStations with chargeInTransit=false. Imagine such a chargingStation being placed in front of a traffic light or at a busStop. Vehicles will occasionally slow down in that area and some of the will charge. If the stoppingThreshold is set to a higher value, then slow moving vehicles may also charge. If it is set to 0, then only vehicles with speed 0 will get the chance to charge.
If you want to influence the speed of EVs (i.e. to let them charge for some time, then you can define a <stop> element to force them to stop at a chargingStation for some time. There is currently no model that would do this automatically for you (e.g. when the battery level is low). regards, Jakob 2018-06-14 17:27 GMT+02:00 Jane Cheung <[email protected]>: > Additional questions, > 1) My understanding of the reply is that the rules that SUMO used to > check whether cars had a braking behavior or not has no relationship with > the attribute *stoppingTreshold**,* > 2) There are two defined ways that EVs could choose when they are > charging (moving or stable.
