dc.description.abstractSmartphones equipped with various sensing abilities and communication interface is the best platform to fulfill the concept of probe car. The smartphone-embedded probe car systems can be used for sensing data collection and communication, and developing Road Information System (RIS) and Traffic Information System (TIS). We apply cloud techniques to efficiently process, analyze and collect lots of sensing data. To achieve the above goals, we need to deal with problems introduced from smartphones and cloud techniques, including sensing problems, e.g., sensor error handles, dynamical smartphone installation and feature extraction; In addition, we need to design user interface for data query and event report; As for cloud techniques, we need to design databases to efficiently process temporal and spatial related data, and develop cloud data processing techniques. In the first year, we will focus on developing prototype system for communication and data collection, and core techniques for mobile sensing. Tasks include studying sources of sensor errors, develop calibration techniques and study advanced sensor utilization techniques, dynamic tri-axis rotation technique for dynamic smartphone installation, developing an interactive cloud-based Traffic Message Channel (TMC) system and studying Hadoop distributed cloud systems. In the second year, we will focus on developing static cloud-based RIS. Tasks include, develop event-based shockwave model discovery algorithms, developing road and traffic condition recognition algorithms, integrating current online databases, handling temporal-spatial related data, e.g., reduction of amount of communication data and database design, and developing static cloud-based traffic and road information systems. In the third year, we will focus on dynamic cloud-based RIS and TIS. Tasks include cloud-based data fusion and mining techniques for temporal-spatial related data, e.g., clustering algorithms for abnormal road conditions and adaptive dynamic traffic data fusion, map-reducer techniques, query techniques for temporal-spatial related and traffic time estimation.en_US
