@ SUMO_TAG_CF_PWAGNER2009
Scalable model based on Krauss by Peter Wagner.
~MSCFModel_PWag2009()
Destructor.
double myDecelDivTau
The precomputed value for myDecel/myTau.
double followSpeed(const MSVehicle *const veh, double speed, double gap2pred, double predSpeed, double predMaxDecel, const MSVehicle *const pred=0, const CalcReason usage=CalcReason::CURRENT) const
Computes the vehicle's safe speed (no dawdling)
double myTauLastDecel
The precomputed value for (minimum headway time)*myDecel.
double getImperfection() const
Get the driver's imperfection.
double myActionPointProbability
The probability for any action.
int getModelID() const
Returns the model's name.
double _v(const MSVehicle *const veh, double speed, double gap, double predSpeed) const
Returns the next velocity.
double patchSpeedBeforeLC(const MSVehicle *veh, double vMin, double vMax) const
apply dawdling
double dawdle(double speed) const
Applies driver imperfection (dawdling / sigma)
virtual MSCFModel::VehicleVariables * createVehicleVariables() const
Returns model specific values which are stored inside a vehicle and must be used with casting.
MSCFModel * duplicate(const MSVehicleType *vtype) const
Duplicates the car-following model.
double myTauDecel
The precomputed value for myDecel*myTau.
double stopSpeed(const MSVehicle *const veh, const double speed, double gap2pred, double decel, const CalcReason usage=CalcReason::CURRENT) const

double finalizeSpeed(MSVehicle *const veh, double vPos) const
Applies interaction with stops and lane changing model influences.
The car-following model abstraction.
