void MSTLLogicControl::WAUTSwitchProcedure_Stretch::cutLogic ( SUMOTime  step,
SUMOTime  startPos,
SUMOTime  allCutTime 
) [protected]

Cuts the logic to synchronize.

Parameters:
[in]stepThe current simulation step
[in]startPosThe position in the destination program to switch to
[in]allCutTimeThe amount by which the logic shall be cut

References MSTLLogicControl::WAUTSwitchProcedure_Stretch::StretchBereichDef::begin, MSTLLogicControl::WAUTSwitchProcedure_Stretch::StretchBereichDef::end, MIN2(), and TIME2STEPS.

Returns the difference between a given time and the start of the phase.

Parameters:
[in]logicThe logic to consider
[in]toTimeThe time to ask for
Returns:
How much time elapsed between the last pahse start and the given time

unsigned int MSTLLogicControl::WAUTSwitchProcedure::getGSPValue ( const MSTrafficLightLogic logic) const [protected, inherited]

Returns the GSP-value.

The GSP must be given as a logic's parameter ("GSP").

Parameters:
[in]logicThe logic to retrieve the GSP from
Returns:
The GSP value; 0 if not given.

MSTrafficLightLogic::getParameterValue

Definition at line 222 of file MSTLLogicControl.cpp.

References MSTrafficLightLogic::getParameterValue().

Returns the number of given Stretch-areas for the given program.

Parameters:
[in]fromThe tls program to get the number of stretch areas from
Returns:
The number of stretch areas

Definition at line 502 of file MSTLLogicControl.cpp.

References MSTrafficLightLogic::getParameterValue(), and toString().

Returns the numbered Stretch-area for the given program.

The first area has normally the number "1", not "0"!

Parameters:
[in]fromThe tls program to get the named stretch area from
[in]indexThe index (identifier) for the area
Returns:
The definition of the stretch area

bool MSTLLogicControl::WAUTSwitchProcedure::isPosAtGSP ( SUMOTime  currentTime,
const MSTrafficLightLogic logic 
) [protected, inherited]

Checks, whether the position of a signal programm is at the GSP ("GuenstigerUmschaltPunkt")

The GSP must be given as a logic's parameter ("GSP"). Not the simulation second, but the phase the GSP lies within is used. If the phase the GSP lies within is the same as the logic's current phase, the result is true.

Parameters:
[in]currentTimeThe current time step
[in]logicThe logic for which this should be examined
Returns:
Whether the current step is the GSP
