New work system for the Traffic Control Room. It is used to supervise the system so that the traffic on the expressway will not stagnate 24 hours a day and 365 days a year. With the concept of Natural Living, operation desks are laid out each functions for various tasks, and light and sound are controlled in the room to facilitate communication among controlling members. User Interfaces (UI) and User Experiences (UX) for data processing are devised for large display screens connecting the control room with various scenes on the expressway, as well as real time data. We designed the new control room in total.
