How do Intelligent Traffic Systems work?

Question

I mean how do they report accidents and other information. Do all this need to be manually entered into the system for reporting or they do it automatically?

Answer 1

Intelligent transportation systems vary in technologies applied, from basic management systems such as car navigation, traffic signal control systems, container management systems, variable message signs, automatic number plate recognition or speed cameras to monitoring applications such as security CCTV systems, and then to more advanced applications which integrate live data and feedback from a number of other sources, such as parking guidance and information systems, weather information, bridge de-icing systems, and the like. Additionally, predictive techniques are being developed, to allow advanced modeling and comparison with historical baseline data.
