Three research work packages related to the central development of multimodal flexible transit service are designed. The first work package focuses on users' route choice behaviour modelling for the multimodal MOD transit service under capacity constraints and social network influence. The second work package focuses on the development of a test bed of the multimodal MOD transit service. An agent-based approach will be used to evaluate different operation design and scenarios for the operators. The third work package focuses on studying potential collaborative strategies and partnerships between public agencies and private service operators. The interactions of different operation designs between private operators and public agencies in the network will be studied based on the stable matching theory.
