摘要

Public transportation network reorganisation can be a key measure in designing more efficient networksand increasing the number of passengers. To date, several authors have proposed models for the “transitroute network design problem” (TRNDP), and many of them use a transit assignment model as onecomponent. However, not all models have considered the “common lines problem,” which is anessential feature in transit network assignment and is based on the concept that the fastest way to get to adestination is to take the first vehicle arriving among an “attractive” set of lines. Thus, we sought toreveal the features of considering the common lines problem by comparing results with and withoutconsidering the problem in a transit assignment model. For comparison, a model similar to a previousone was used, formulated as a bi-level optimisation problem, the upper problem of which is described asa multi-objective problem. As a result, although the solutions with and without considering the commonlines showed almost the same Pareto front, we confirmed that a more direct service is provided if thecommon lines problem is considered whereas a less direct service is provided if it is not. With a smallnetwork case study, we found that considering the common lines problem in the TRNDP is important asit allows operators to provide more direct services.
