Abstract

Abstract
By the end of the second millennium, metropolitan Regions have been struggling with population and activity with radical transformations; one of the most important consequences of this process is the injustice in the distribution of job opportunities. The present study seeks to improve the accessibility of the transportation network for the population with the most needs in the Tehran metropolitan region. This research uses inductive strategy and quantitative research methodology to answer research questions. The data collected from the Statistical Centre of Iran and Road Maintenance & Transportation Organization of Iran has been analyzed using the coordinate system of potential mobility and accessibility to employment with cumulative and gravity methods, and inefficiencies accessibility through the fairness accessibility index in Arc GIS and Excel software. Findings indicate that access to employment in the region is reduced by a distance from the central bar, and many of the northern and northwestern areas are inaccessible. The percentage of sub-threshold populations, respectively, decreases from 50% to 10% by 48% to 2%, and the share of sub-threshold areas from 3.5% to 1%. The share of the population below the threshold of the total population for the thresholds is about 50% at around 13% and reaches 0.5% on the threshold of 10%; These population groups are potentially eligible for improvement in their accessibility. Finally, by conclusion on the methods: Asara, Taleqan, Lavasan, Nesa, Barghan, Joestan, Paein Taleqan and Miyan Taleqan settlements with a population of 47678 are in the priority of improving accessibility.
