我们研究允许任意(有意义) 公共交通、步行和乘坐汽车/出租车的组合。在简单模型中,帕累托最优解的数量激增。事实证明,他们中的许多人彼此相似或不合理。我们引入了一个新的过滤程序,类型aNd的holds(TNT),这导致了一个小而有代表性的子集的合理路径。我们考虑像纽约这样的大都市地区,在那里快速计算路径是困难的。为了减少高计算时间,最优保持和启发式 方法介绍。我们实验评估我们的方法,结果质量和查询时间。实验证实,我们的结果集确实很小(每个查询约5个结果)和代表性(在合理的帕累托最优路径中),平均查询时间约为1秒或更少。
We study multi-modal route planning allowing arbitrary (meaningful) combinations of public transportation, walking, and taking a car / taxi. In the straightforward model, the number of Pareto-optimal solutions explodes. It turns out that many of them are similar to each other or unreasonable. We introduce a new filtering procedure, Types aNd Thresholds (TNT), which leads to a small yet representative subset of the reasonable paths. We consider metropolitan areas like New York, where a fast computation of the paths is difficult. To reduce the high computation times, optimality-preserving and heuristic approaches are introduced. We experimentally evaluate our approach with respect to result quality and query time. The experiments confirm that our result sets are indeed small (around 5 results per query) and representative (among the reasonable Pareto-optimal paths), and with average query times of about one second or less.
