In order to encourage people to use alternative transport solutions while reducing the disproportional use of cars, studies that could provide relevant information to stakeholders and policymakers are required. This is due to the excessive use of cars and its negative externalities, such as traffic congestion and the production of high levels of carbon dioxide (CO2). Therefore, one strategy is to improve public transport by providing a fair level of access to it for the people to encourage them to have a multimodal behavior regarding transport. This thesis proposes a methodology to assess public transportation accessibility inequity of land parcels served by transit systems in metropolitan areas.
