Operators-Users Equilibrium Model in a Partially Regulated Transit System

We present two formulations of a model for nding equilibrium passengers and operators ows in a partially regulated transit system where bus operators are free to choose the routes where they o er public transport services. The transit fares are assumed xed and known. The model o ers a detailed representation of the transit system network and of the transit users behavior. Congestion e ects are also considered as a consequence of cars and buses operation over a common road network. Two algorithmic solution approaches are investigated.
