This document discusses Intelligent Transportation Systems (ITS) and how they aim to enhance transportation efficiency and safety. ITS uses sensors, communication technologies, and traffic control to gather data on traffic volume, vehicle classification, speed, delays, and more. This data is then used to manage traffic flow and provide travelers with real-time transportation information. Floating car data is also discussed, which uses GPS or mobile phones in vehicles to anonymously collect location and speed data to monitor traffic conditions across road networks. The goals of ITS include improving safety, reducing congestion, providing travel/transit information to the public, saving costs, and lowering environmental impacts.
