  3. Abstract:
  4. Equity in distribution is one of the most controversial and essential concepts which for a long time has been the central concern of political philosophers when considering planning concerns of the societies. Transport is a key field by which politicians and decision-makers impose their intention on societies. Although there have been studies discussing equity in transport, yet there is no clear mathematical framework to utilize the equity concept in transportation planning. This study has reviewed equity in transportation, as well as in human science studies to investigate and determine how transportation advantages should be equitably distributed among society members. This review has led to a relatively comprehensive picture, comparatively relating equity theories. "Transportation accessibility" has been chosen to be distributed as a widely used measure presenting transportation advantages. Dissimilar to other studies, this study has proposed activity-based accessibility measure as the distribution variable. Finally, to represent equity theories in mathematical forms, network design problem context was employed. These theories are expressed in maximization or minimization objective function forms along with logical constraints. These mathematical forms are ready to be used for practical purposes
