Models for Line Planning in Public Transport |
Abstract: The line planning problem is one of the fundamental
problems in strategic planning of public and rail transport. It consists of finding
lines and corresponding frequencies in a public transport network such that a given
travel demand can be satisfied. There are (at least) two objectives. The transport
company wishes to minimize its operating cost; the passengers request short travel
times. We propose two new multi-commodity flow models for line planning. Their main
features, in comparison to existing models, are that the passenger paths can be
freely routed and that the lines are generated dynamically.
