checkChangeBeforeCommitting()

virtual int MSAbstractLaneChangeModel::checkChangeBeforeCommitting ( const MSVehicle * veh, int state ) const

inlinevirtualinherited

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

veh	the lane changing vehicle
state	current 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]	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

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.
