Integrating passenger and freight transportation : model formulation and insights

Abstract

Integrating passenger and freight \nows creates attractive business opportunities because the\nsame transportation needs can be met with fewer vehicles and emissions. This paper seeks an\nintegrated solution for the transportation of passenger and freight simultaneously, so that fewer\nvehicles are required. The newly introduced problem concerns scheduling a set of vehicles to\nserve the requests such that a part of the journey can be carried out on a scheduled passenger\ntransportation service. We propose an arc-based mixed integer programming formulation for\nthe integrated transportation system. Computational results on a set of instances provide a\nclear understanding on the benets of integrating passenger and freight transportation in the\ncurrent networks, considering multi-modality of traditional passenger-oriented transportation\nmodes, such as taxi, bus, train or tram.
