Abstract: A piece of luggage including a main body and a power supplying module is disclosed. The main body includes a moving module including a plurality of wheels and a main motor and a power unit electrically connected to the moving module. The wheels include an active wheel electrically connected to the main motor. The power supplying module includes a power supplying unit including a power supplying box and a battery and a connecting unit including a connecting part, a holding part and a conducting wire. The power supplying box has an output port. The battery is disposed in the power supplying box and electrically connected to the output port. The connecting part has a power port corresponding to the output port. The holding part and the conducting wire are connected to the connecting part. The conducting wire is electrically connected to the power port and the power unit.

Abstract: A real-time traffic safety visualization and management system using traffic data, social media data, weather data, and other similar data enable proactive decisions for reducing the number of traffic incidents or mitigating their severity. The system utilizes predictive algorithms in a hybrid framework to diagnose real-time traffic safety conditions. Meanwhile, Pro-active Traffic Management (PATM) Strategies are provided by the system for the predicted high-risk locations. Moreover, through the visualization and management system, various countermeasures are considered and tested for decision makers, such that one or more of the most effective countermeasures are recommended within a given area to improve traffic safety thereof.
