Abstract

We present an extension of the well-known time-expanded approach
for timetable information. By remodeling unimportant stations, we are able to
obtain faster query times with less space consumption than the original model.
Moreover, we show that our extensions harmonize well with speed-up techniques
whose adaption to timetable networks is more challenging than one might expect.
