A comparative assessment of multi-sensor data fusion techniques for freeway traffic speed estimation using microsimulation modeling

Real-time traffic speed estimation is a fundamental task for urban traffic management centers and is often a critical element of Intelligent Transportation Systems (ITS). For this purpose, various sensors are used to collect traffic information. For many applications, the information provided by individual sensors is incomplete, inaccurate and/or unreliable. Therefore, a fusion based estimate provides a more effective approach towards traffic …
