Travelling by subway between work or study and home is quite usual. But the experience of metro-riding is not fun and always puts a lot of stress on the commuters. People feel very stressed when they are on the way to catch the train. Bad phenomenon often occurs at boarding. My project is about giving those commuters an easier and more interesting metro-riding experience. The concept is to communicate information better with the commuters. I prototype a core system based on a rhythm pacing idea by designing an App for easier and interesting time management and a digital signage gate for showing crowd levels of each carriage to help split the crowd and keep the waiting queue in good order on the platform.
