Today, many people use public transportation as a way of traveling. Among different types of public transportation, people frequently use the subway as they can move from one location to another more conveniently with the extended underground pathways. However, we currently lack a service system that informs us whether the subway has arrived or not, or is on the way when we are on our way to take a subway. Consequently, subway users experience a great deal of inconvenience. Hence, a design is proposed that informs the subway users about the current subway operation status in real-time by indicating LED colors on the handrail of the escalator.
