Abstract Integrating passenger and freight flows creates attractive business opportunities because the same transportation needs can be met with fewer vehicles and emissions. This paper seeks an integrated solution for the transportation of passenger and freight simultaneously, so that fewer vehicles are required. The newly introduced problem concerns scheduling a set of vehicles to serve the requests such that a part of the journey can be carried out on a scheduled passenger transportation service. We propose an arc-based mixed integer programming formulation for the integrated transportation system. Computational results on a set of instances provide a clear understanding on the benefits of integrating passenger and freight transportation in the current networks, considering multi-modality of traditional passenger-oriented transportation modes, such as taxi, bus, train or tram. Keywords: Combining passengers and freight, routing & scheduling, multi-modal transportation, pickup and delivery problems. 1. Introduction A successful integration of passenger and freight transportation creates a seamless movement for the people and parcels. This integration achieves socially desirable transport options economically viable in urban areas as it reduces congestion and air pollution. Actual integration is being already observed in long-haul freight transportation: passenger aircrafts and ferries, such as Norwegian Hurtigruten carry freight and people at the same time (Levin et al., 2012; Hurtigruten, 2013). In short-haul transportation, however, people and freight rarely share transportation modes although they largely share the same infrastructure, indicating the potential efficiency gains for an integrated approach (Lindholm and Behrends, 2012). To our knowledge, this integrated transport solution has not been sufficiently taken into consideration in the literature. In this paper, we propose novel conceptual and mathematical models for the integrated Email address: V.Ghilas@tue.nl, E.Demir@tue.nl, T.v.Woensel@tue.nl (Veaceslav Ghilas*, Emrah Demir and Tom Van Woensel) * Corresponding author, Tel. +31 633 193 838
