The early voting system started in 2014 has been paid attention as a new alternative for increasing a voting rate by improving voters convenience. Improper locations of early voting polls typically based on the administrative unit and management cannot provide a better service for voters voting convenience actually. In this regard, this paper examines the exiting system of early voting in a systematic way, and attempts to suggest various locational solutions for early voting polls using spatial optimization techniques which maximize spatial accessibility of voting polls. Specifically, we present the optimal locations of newly sited early voting polls by considering actual demands of early voters based on floating population and workers distributions in Seocho and Gangnam-gu, Seoul. The major results are thought of as the enhanced spatial plans for providing better spatial accessibility and voting equity among different population administrative units, and they would be utilized as theoretical and empirical references when planning new places or replacements of early voting polls for further elections.
