Improving Transportation Information Resilience: Error Estimation for Networked Sensor Data

Reliable and resilient data serves as a critical foundation for almost all new mobility technologies in a modern transportation system, thus plays a significant role in improving the efficiency, safety, and ultimately sustainability of a transportation system. Despite the importance of sensor data performance evaluation, research effort devoted to this subject is rather small compared to studies that directly take sensor data as input. Most sensor health monitoring studies focused on identifying ‘bad’ sensors whose data should be discarded. The problem of estimating and correcting the systematic bias of sensor data has not been addressed, especially in the context of large-scale networked data pieces from heterogeneous sources. The researcher aims to fill this critical gap by combining data science and network modeling techniques to provide greater modeling flexibility. The incorporation of spatial correlation of networked data leads to better estimation quality. Knowledge transfer from academia to practice will be strengthened through an open-source tool for sensor performance evaluation and visualization to be shared with transportation agencies. This research will improve fundamental knowledge on transportation data analytics as well as the effective management of data and information infrastructure in transportation practice.
