Abstract:	This dissertation aims to investigate green transportation strategies in multimodal networks while preserving mobility and to assess corresponding travel efficiency from a network point of view. Green transportation is advocated worldwide to reduce the environmental impact caused by transportation sector. However, the promotion of green transportation fails easily without considering mobility. This dissertation focuses on green transportation in urban multimodal networks. Various transport modes are usually involved and trips can be accomplished with more than one pattern. The first part of this dissertation develops a green index to evaluate the sustainability of different paths of origin-destination (OD) pairs in urban transportation networks. The study proposes a new idea to increase the accessibility of MRT stations in Taipei City by using convenience stores as transfer points. Convenience stores are densely distributed in Taipei City, and connect activity and transportation networks. They are important delivery points in Taipei. Furthermore, this dissertation proposes green feeder alternatives to carry travelers from convenience stores to MRT stations. A Monte Carlo simulation of thousands of OD pairs in Taipei City is conducted to examine proposed strategies. The second part of this dissertation applies small-world theory to investigate the proposed networks, which are current multimodal networks incorporating green transfer nodes. The green transportation connectivity efficiency and mobility in global and local scales are explored. A series of case studies in Taipei City are performed to demonstrate the applications of this dissertation. The results indicate that for short trips, commuters can directly use electric motorcycles by renting and returning those at convenience stores of origins and destinations. For medium and long trips, commuters can take green transport modes at convenience stores to access MRT stations. Electric motorcycles are effective green feeder modes, and electric feeder buses can be an alternative of green feeder modes for long trips. The results also show that the global mobility and local mobility of the proposed networks are more than 55%. It implies that travelers can travel from any district to any other districts with green transportation in a rather efficient way. In addition, the results show that Wan-hua is the district where the first trial of incorporating convenience stores in transportation networks should be conducted. In the proposed network, the local mobility of Wan-hua and Xin-yi districts is more than 66%, which indicates that travelers in Wan-hua and Xin-yi districts can reach any important destinations more efficiently than those in other districts.
