Hello, The wiedemann model also uses the common vType paramters 'accel', 'decel', 'emergencyDecel', and 'length' There are further parameters (i.e. regarding the variance of the random components) that are currently hard-coded in src/microsim/cfmodels/MSCFModel_Wiedemann.cpp (in the constructor, as well as in the functions _v and fullspeed).
We haven't been using the model much so we did not yet make all these parameters available for calibration (most of them are tied to 'security' and 'estimation' so you can influence them). there is no further documentation beyond the code (which is thankfully quite short). regards, Jakob 2018-05-17 0:28 GMT+02:00 Gopindra Sivakumar Nair via sumo-user < [email protected]>: > Hi, > > I was going through the documentation at, > http://www.sumo.dlr.de/userdoc/Definition_of_Vehicles,_Vehicle_Types,_and_ > Routes.html > to understand the different attributes that are required by each car > following model.
