extends AbstractLaneBasedTacticalPlanner
Lane-based tactical planner that implements car following behavior and rule-based lane change. This tactical planner retrieves the car following model from the strategical planner and will generate an operational plan for the GTU.

A lane change occurs when:

  1. The route indicates that the current lane does not lead to the destination; main choices are the time when the GTU switches to the "right" lane, and what should happen when the split gets closer and the lane change has failed. Observations indicate that vehicles if necessary stop in their current lane until they can go to the desired lane. A lane drop is automatically part of this implementation, because the lane with a lane drop will not lead to the GTU's destination.
  2. The desired speed of the vehicle is a particular delta-speed higher than its predecessor, the headway to the predecessor in the current lane has exceeded a certain value, it is allowed to change to the target lane, the target lane lies on the GTU's route, and the gap in the target lane is acceptable (including the evaluation of the perceived speed of a following GTU in the target lane).
  3. The current lane is not the optimum lane given the traffic rules (for example, to keep right), the headway to the predecessor on the target lane is greater than a certain value, the speed of the predecessor on the target lane is greater than or equal to our speed, the target lane is on the route, it is allowed to switch to the target lane, and the gap at the target lane is acceptable (including the perceived speed of any vehicle in front or behind on the target lane).

This lane-based tactical planner makes decisions based on headway (GTU following model). It can ask the strategic planner for assistance on the route to take when the network splits.
