What is Equality of public transit connectivity: the influence of mass rapid transit services on individual buildings for Singapore about?

Accessibility and its equality are key factors for land-use and transport planning in city developments. In this paper, we propose a graph-based Public Transit Connectivity (PTC) index to measure the accessibility of individual buildings focusing on transportation factors. A large-scale graph is created to connect all buildings in the city through multi-modal public transit services. The PTC index of each building is calculated based on the doorto-door travel distance/time from the building to all others using a parallel graph closeness centrality algorithm. In addition, the PTC index is verified from an economic perspective, as it is highly correlative to house resale price and thus enable accurate price prediction using machine learning models. Consequently, the PTC index and its equality are used to evaluate the influence of existing and future Mass Rapid Transit (MRT) services in Singapore as a case study. As experimental results show, MRT services significantly enhance PTC indices of individual buildings. However, they could not improve PTC equality in city scale due to their conflicting effects, i.e. (1) shrinking the difference between central and peripheral regions and (2)
