inline

Returns the index of the end point of the interval in which the position is

Parameters

s	Position to be searched

Returns

Index of the interval

getIndexBefore()

unsigned int agent_model::VelocityHorizon::getIndexBefore ( double  s )

inline

Returns the index of the start point of the interval in which the position is

Parameters

s	Position to be searched

Returns

Index of the interval

getSpeedAt()

double agent_model::VelocityHorizon::getSpeedAt ( unsigned int  i )

inlineprotected

Returns the minimum of the speed at the given index

Parameters

i

Index

Returns

Minimum speed

init()

void agent_model::VelocityHorizon::init ( double  offset, unsigned int  noOfElements  )

inline

Initializes the points container

Parameters

offset	Position offset of the horizon

inline

Updates the maximum total velocity

Parameters

v	Velocity to be set

update()

void agent_model::VelocityHorizon::update ( double  s )

inline

Updates the horizon to the new reference position Removes all elements with a distance smaller than zero, except of the first one smaller than zero.

Parameters

s	New reference position

updateContinuousPoint()

void agent_model::VelocityHorizon::updateContinuousPoint ( double  s, double  v  )

inline

Updates the continuous velocity profile at the given point

Parameters
