public abstract class AbstractLaneBasedGTU
extends AbstractGTU
implements LaneBasedGTU

This class contains most of the code that is needed to run a lane based GTU.
The starting point of a LaneBasedTU is that it can be in multiple lanes at the same time. This can be due to a lane change (lateral), or due to crossing a link (front of the GTU is on another Lane than rear of the GTU). If a Lane is shorter than the length of the GTU (e.g. when we do node expansion on a crossing, this is very well possible), a GTU could occupy dozens of Lanes at the same time.

When calculating a headway, the GTU has to look in successive lanes. When Lanes (or underlying CrossSectionLinks) diverge, the headway algorithms have to look at multiple Lanes and return the minimum headway in each of the Lanes. When the Lanes (or underlying CrossSectionLinks) converge, "parallel" traffic is not taken into account in the headway calculation. Instead, gap acceptance algorithms or their equivalent should guide the merging behavior.

To decide its movement, an AbstractLaneBasedGTU applies its car following algorithm and lane change algorithm to set the acceleration and any lane change operation to perform. It then schedules the triggers that will add it to subsequent lanes and remove it from current lanes as needed during the time step that is has committed to. Finally, it re-schedules its next movement evaluation with the simulator.
