Driving Behavior
the vehicle is inside the lane change distance of this connector (ignoring
the flag "lane change distance per lane") the vehicle moves laterally on
its lane to the respective side and vehicles which do not want to turn at
the same connector or earlier on the same side try not to overtake the
vehicle on that side. (In previous versions, only the immediate next
connector was checked, and the lane change distance was ignored.)
With the *.INP file, a data row consisting of the three driving behavior
parameters for lateral behavior is stored on top of the
AMBER_BEHAVIOR data row in this case.

Please note, that the default values of the latter two AMBER_BEHAVIOR
parameters can only be modified manually in the *.INP file.
These parameters work as follows:
Parameter Meaning
TURN The direction (left / right / through (= "all")) of
the next turning movement (i.e. the next
connector of the vehicle's route) is taken into
consideration:
● The vehicle does not change the lateral
position in order to overtake a vehicle on
the wrong side (since this would cause a
collision at the next intersection)
● The vehicle moves laterally on the lane to
the side of the next turn if there is room.
Option Consider next turning direction has precedence
over option Desired position at free
flow.
Please note, that the lane change distance of
the connector is ignored so far and only the
