The necessity of shifting the policy focus from supply-side initiatives such as physical-capacity expansion to demand-side initiatives including ease of congestion is newly rising as a compelling method of improving the general ride quality of the metro users. In an effort to catch up with such shifting trend, a system schematic that will update the congestion status of the metro lines via mobile devices is suggested through this study, along with the development of a smartphone application to realize this service idea. The developed smartphone application allows the metro passengers to identify the congested area of each station platform and to receive information on the congestion level of each train and car. Through such assistance, the metro congestion information system can improve the overall convenience of the metro passengers by helping them identify the congestion level across the metro lines.
