void MSLCM_LC2013::addLCSpeedAdvice ( const double  vSafe)
protected

Takes a vSafe (speed advice for speed in the next simulation step), converts it into an acceleration and stores it into myLCAccelerationAdvices.

Note
This construction was introduced to deal with action step lengths, where operation on the speed in the next sim step had to be replaced by acceleration throughout the next action step.

Called to adapt the speed in order to allow a lane change. It uses information on LC-related desired speed-changes from the call to wantsChange() at the end of the previous simulation step.

Parameters
minThe minimum resulting speed
wantedThe aspired speed of the car following model
maxThe maximum resulting speed
cfModelThe model used
Returns
the new speed of the vehicle as proposed by the lane changer

The target lane for the vehicle's current maneuver.

Note
This is used by the sublane model to register the vehicle at lanes, it will reach within the current action step, so vehicles on that lane may react to the started lc-maneuver during the car-following process. If the shadow lane is the same as the lc maneuver target, myTargetLane is set to nullptr. The current shadow lanes and further lanes should always be updated before updating the target lane.
