The system can react instantly with planned travel times using a car or public transport using real-time data. The collected information may represent traffic flow, travel time, optimal route, air quality, weather 1. Identify the type of requested system : ubiquitous, mobile distributed. Justify your choice 2. Identify the required equipments for the implementation of this system. Explain the role and type of each equipment.
