Integrated solution for anomalous driving detection based on BeiDou/GPS/IMU measurements

There has been an increasing role played by Global Navigation Satellite Systems (GNSS) in Intelligent Transportation System (ITS) applications in recent decades. In particular, centimeter/decimetre positioning accuracy is required for some safety related applications, such as lane control, collision avoidance, and intelligent speed assistance. Lane-level Anomalous driving detection underpins these safety-related ITS applications. The two major issues associated with such detection are (1) accessing high accuracy vehicle positioning and dynamic parameters; and (2) extraction of irregular driving patterns from such information. This paper introduces a new integrated framework for detecting lane-level anomalous driving, by combining Global Positioning Systems (GPS), BeiDou, and Inertial Measurement Unit (IMU) with advanced algorithms. Specifically, we use Unscented Particle Filter (UPF) to perform data fusion with different positioning sources. The detection of different types of Anomalous driving is achieved based on the application of a Fuzzy Inference System (FIS) with a newly introduced velocity-based indicator. The framework proposed in this paper yield significantly improved accuracy in terms of positioning and Anomalous driving detection compared to state-of-the-art, while offering an economically viable solution for performing these tasks.

Integrated coastal water monitoring

Geographical Information Systems (GIS) are important took for environmental monitoring and management. However, their limitations in dealing with complex, dynamic, and mission‐critical situations call for alternative approaches. Integrating GIS with dynamic simulation models offers one such solution. Numerical models that simulate physical, chemical, and biological processes greatly increase our understanding of the environment. Many of these models use refined forecast information to accurately predict processes that help in monitoring and managing the environment. Integrating these models with GIS offers new functionalities. The present research couples the MIKE21 comprehensive modeling system for two‐dimensional free surface flows with the spatial analysis strengths of the ArcView GIS. The southern coastal water system of Singapore serves as the study area. The aim is to develop a comprehensive software system that provides support for both environmental managers and land‐use planners in making their decisions.
