Evaluation model for local transit effectiveness to support the service design in weak demand areas

In a public transport network, an integration between lines generally involves, on one hand, the reduction in the number of direct links, which forces users to perform more vehicle switches, and on the other hand, the possibility of supplying a greater number of rides with the same mileage. Thus, the conversion of a direct link scheme to a feeder-trunk one to improve transit service efficiency in weak demand areas produces both negative and positive effects on accessibility. This paper deals with the built of a model able to estimate an equivalent travel time, taking into account the discomfort caused to users by the vehicle switch and the benefit arising from the greater availability of public transit rides. To validate this model and highlight benefits and limitations resulting from feeder-trunk supply schemes an application to a case study was developed.
