◆ addLCSpeedAdvice()

void MSAbstractLaneChangeModel::addLCSpeedAdvice	(	const double	vSafe,

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.

◆ estimateLCDuration()

double MSAbstractLaneChangeModel::estimateLCDuration	(	const double	speed,

virtual

Calculates the maximal time needed to complete a lane change maneuver if lcMaxSpeedLatFactor and lcMaxSpeedStanding are set and the vehicle breaks not harder than decel. LC when the vehicle starts breaking now. If lcMaxSpeedStanding==0 the completion may be impossible,.

Parameters

[in]	speed	Current longitudinal speed of the changing vehicle.
[in]	remainingManeuverDist	dist which is still to be covered until LC is completed
[in]	decel	Maximal assumed deceleration rate applied during the LC.

Returns: maximal LC duration (or -1) if it is possible that it can't be completed.

Note: 1) For the calculation it is assumed that the vehicle starts breaking with decel (>=0) immediately. If lcMaxSpeedStanding==0 the completion may be impossible, and -1 is returned. 2) In case that no maxSpeedLat is used to control lane changing, this is only called prior to a lane change, and the duration is MSGlobals::gLaneChangeDuration.

◆ myTargetLane

MSLane* MSAbstractLaneChangeModel::myTargetLane

protected

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.
