Field Summary

Fields

Modifier and Type	Field and Description
static Tailgating	NONE No tailgating.
static Tailgating	PRESSURE Tailgating based on speed pressure.
static ParameterTypeDouble	RHO Social pressure applied to the leader.
static Tailgating	RHO_ONLY No tailgating, but social pressure exists.

Method Summary

Modifier and Type	Method and Description
static double	socialPressure(Speed speed, Speed vCong, Speed desiredSpeed, Speed leaderSpeed, Speed vGain, Length headway, Length x0) Returns a normalized social pressure, equal to (vDesired - vLead) / vGain.
void	tailgate(LanePerception perception, Parameters parameters) Apply tailgating.

Field Detail

RHO

static final ParameterTypeDouble RHO

Social pressure applied to the leader.

NONE

static final Tailgating NONE

RHO_ONLY

static final Tailgating RHO_ONLY

No tailgating, but social pressure exists.

PRESSURE

static final Tailgating PRESSURE

Tailgating based on speed pressure.

Method Detail

socialPressure

static double socialPressure(Speed speed,
                             Speed vCong,
                             Speed desiredSpeed,
                             Speed leaderSpeed,
                             Speed vGain,
                             Length headway,
