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.

Informs the vehicle that it is about to be moved on an adjacent lane. The method can be used to re-evaluate the state of the vehicle and potentially abort the lane change. By default, if the method is not overridden by the lane change model implementation, nothing is altered and the vehicle will perform the lane change.

Parameters
vehthe lane changing vehicle
statecurrent lane change state
Returns
the blocked status of the vehicle. If the vehicle should perform the lane change, the method should return 0, corresponding to non-blocked. Otherwise the method should return a non-zero state, corresponding to the type of blockage.

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]speedCurrent longitudinal speed of the changing vehicle.
[in]remainingManeuverDistdist which is still to be covered until LC is completed
[in]decelMaximal 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
protectedinherited

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.
