Chapter V. Conclusions


This study was motivated by the necessity of improving the feeder services for the suburban cities of a metropolitan area. The study’s primary concern in this regard is to facilitate the shared-use mobility, defined as the transportation service based on the shared-use economy. Particularly, this study aims at supporting the shared-use mobility as the feeder service to access the mobility hubs, which are typically formed at the major transit stations for metropolitan intercity trips.
As the study’s main outputs, the shared-use mobility strategies were derived by considering both the mode-specific needs of shared-use mobility as well as the
characteristics of mobility hubs. In this regard, this study focused on the three modes: car sharing, bikes haring, and ridesharing. The needs of these three modes were identified by reviewing a previous survey as well as relevant foreign policies to shed light on suitable service strategies. In addition, strategies on the facility development were derived to aid the operations of shared-use mobility. For this purpose, a framework to quantify the characteristics of mobility hubs were developed and then applied to a case study of Seoul metropolitan area for an illustration. In the case study, 12 mobility hubs were grouped into 4 types, which are ‘metropolitan hubs with high-density development’, ‘metropolitan hubs with low-density development’, ‘municipal hubs with high-density development’, and ‘municipal hubs with low-density development.’ Based on this categorization, investment strategies were recommended by identifying highly prioritized modes of the shared-use mobility at the individual hubs.This study has some limitations although it has contributions in establishing the procedure to analyze the needs of introducing the shared-use mobility for the metropolitan feeder services. Most of all, the mobility hubs could not be categorized in a statistically robust manner because this study selected only 12 hub samples for the sake of illustration. In light of this, additional analyses are worthwhile to confirm or revise this
study’s results by analyzing relevant data associated with a more extensive set of hub samples. Moreover, further research is required to quantify the impacts of introducing the shared-use feeder services on the metropolitan transportation system as a whole.
