User-Constrained Multimodal Route Planning
2015
ACM Journal of Experimental Algorithmics
Preserved Fulltext
In the multi-modal route planning problem we are given multiple transportation networks (e. g., pedestrian, road, public transit) and ask for a best integrated journey between two points. ...
In fact, quickly computing reasonable multimodal routes remains a challenging problem: Previous approaches either suffer from poor query performance or their available choices of modal preferences during ...
We thank Daniel Delling for interesting discussions on multi-modal route planning, and Geisberger et al. for providing us their CH code. ...
