TxDOT uses unmanned aircraft systems (UAS) for various applications in Texas such as highway mapping, bridge inspection, crash site data collection and real- time traffic monitoring. Environmental conditions including wind, rain, mist, smoke, and ambient lighting affect both the flight operations of the UAS aircraft and the quality of the data being collected. However, due to logistics, scheduling, and urgency, UAS flights may need to be performed during suboptimal conditions. To better understand these effects, this research will address key challenges of UAS operations in suboptimal conditions, provide guidance for UAS flight operations in suboptimal conditions, and recommend settings, procedures and workflows to ensure data quality collected by UAS in suboptimal conditions. This research includes a literature review of the state of the art and the state of the practice, simulation and laboratory tests, preliminary field testing of UAS flight operations and data collection in different suboptimal environmental scenarios, post-flight analytics and assessments, and the development of recommendations and guidance for UAS operations in suboptimal conditions. |
