◆ estimateLCDuration()

double MSAbstractLaneChangeModel::estimateLCDuration ( const double  speed,

virtualinherited

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.

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.
