This class is no longer in use. The TimeCostDensityVoronoi measures the density by generating an jts-diagram for the whole area of the scenario. This has a complexity of O(N*log(N)) for each computation. We count the pedestrians and the area size of all jts-regions in an specific area. D = N * (min possilbe jts area) /(sum of all jts cell areas) for those jts cell who's site is inside the measurement area (a square). This is only working if no obstacles inside the area of the jts-diagram!!!
the time cost function for the decorator-pattern.
---
the jts-diagram which has to be recomputed in every step.
the width and height of the measurement area (a square).
---
the cached voronoiAreas, to avoid recomputing.
the weight of the density.
