Abstract

This paper considers a mass transit system in a regional area. The problem of improving the quality of the service in terms of costs perceived by the passenger is studied. A model to improve the effectiveness of the system maintaining the feasibility of the traffic assignment is proposed, along with new definitions of passenger assignment to support the proposed model. 1. Introduction In this paper we will consider a mass transit system in a regional area where both road and rail transportation may be used by commuters. Unlike the urban case [10], in a regional mass transit system, line frequencies are relatively low and trips can be considered as singular entities. We will assume that all the trips run on time according to a given time-table which is known by users; in addition, the vehicles have a fixed capacity (number of seats) which cannot be exceeded. Often transit companies have to cope with the problem of improving the level of service perceived by the users without increasing...
