Edges as Nodes - a New Approach to Timetable Information
| pdf-format: |

Abstract
In this paper we suggest a new approach to timetable information byintroducing the ``edge-converted graph'' of a timetable.
Using this model we present simple algorithms that solve the
earliest arrival problem (EAP) and the minimum number of transfers problem
(MNTP).
For constant-degree graphs this yields linear-time algorithms for EAP and
MNTP which improves upon the known \emph{Dijkstra}-based approaches.
We also test the performance of our algorithms against the classical
algorithms for EAP and MNTP in the time-expanded model.
