@ SUMO_TAG_CF_DANIEL1
The original Krauss (1998) car-following model and parameter.
~MSCFModel_Daniel1()
Destructor.
double myTmp1
temporary (testing) parameter
virtual MSCFModel * duplicate(const MSVehicleType *vtype) const
Duplicates the car-following model.
double myDawdle
The vehicle's dawdle-parameter. 0 for no dawdling, 1 for max.
void setImperfection(double imperfection)
Sets a new value for driver imperfection.
double getImperfection() const
Get the driver's imperfection.
MSCFModel_Daniel1(const MSVehicleType *vtype)
Constructor.
virtual int getModelID() const
Returns the model's name.
virtual 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 myTauDecel
The precomputed value for myDecel*myTau.
virtual double stopSpeed(const MSVehicle *const veh, const double speed, double gap2pred, double decel, const CalcReason usage=CalcReason::CURRENT) const
Computes the vehicle's safe speed for approaching a non-moving obstacle (no dawdling)
virtual double dawdle(double speed, SumoRNG *rng) const
Applies driver imperfection (dawdling / sigma)
void setHeadwayTime(double headwayTime)
Sets a new value for driver reaction time [s].
virtual double _vsafe(double gap, double predSpeed) const
Returns the "safe" velocity.
void setMaxDecel(double decel)
Sets a new value for maximum deceleration [m/s^2].
double finalizeSpeed(MSVehicle *const veh, double vPos) const
Applies interaction with stops and lane changing model influences.
The car-following model abstraction.
Definition: MSCFModel.h:55
CalcReason
