Hello Jakob, Thank you for your response. I have set the required vType parameters as directed.
<vType carFollowModel="Krauss" color="0,1,0" id="veh" latAlignment="center" length="5" sigma="0" speedDev="0" speedFactor="1.0" lcOvertakeRight="1" lcLookaheadLeft="1" lcKeepRight="0" lcSpeedGainRight="1" /> Additionally, I have also set lcSpeedGainRight="1" since the documentation mentioned that will achieve symmetry, though I'm not sure. What I understand is that it will prefer to lane change to the rightmost lane for speed gain, unless it is set to 1? On a side note, some of these parameters have a range that extends to infinity. For example, To set lcSublane to infinity, do you just write lcSublane="infinity"?
