Transportation-related social exclusion occurs when individuals suffer both transport disadvantages and social disadvantages because they have difficulty obtaining the services and employment opportunities they need. According to the previous studies, launching a metro system has been proved to affect travel costs among locations immediately and geographical distributions of population and employment in the long term. Such effects gradually reshape job accessibility and socio-economic conditions of an area and could eventually exclude economically disadvantaged people from access to jobs. However, there is very limited research on metro-induced exclusiveness in the literature.
This research explores the long-term impacts of metro infrastructure on social exclusion applying the data from 1996 to 2016 in Taipei, Taiwan. An exclusion index (the difference between job accessibility and deprivation) is proposed to measure the exclusiveness of an area. Then, panel data regression models are applied to elucidate the associations of proximity to metro stations with social exclusion.
The empirical results reveal that developing metro infrastructure worsened the exclusion of economically disadvantaged people from job opportunities in the past 20 years in Taipei. Through the results, in addition to observing the associations of geographical alterations of job accessibility and socio-economic conditions with the metro system in the long term, the proposed exclusion index also helps planners to clarify the role of public transportation in promoting transport equity.
