Commenting on the connectivity issues for some remote and central estates, SMU Assistant Professor of Strategy & Entrepreneurship (Education) Terence Fan said that for areas where it could take a while to get to the train station via bus, it would be helpful for residents to get a rail connection, perhaps with a combination of the Light Rail Transit system to maintain efficiency. He explained why Singapore's public transport network is more comparable to Tokyo's rather than London, due to Tokyo's extensive coverage and the two cities' high population density. Asst Prof Fan also said that Singapore may be well-connected by global city standards, but within the local context, there is room for improvement. He added that the high Certificate of Entitlement prices now indicate the increasing priority that Singaporeans place on time, and how people are willing to spend more to reduce commute times.
