Alfalfa canopy structure reveals useful information for managing this forage crop, but manual measurements are impractical at field-scale. Photogrammetry processing with images from Unmanned Aerial Vehicles (UAVs) can create a field-wide three-dimensional model of the crop canopy. The goal of this study was to determine the appropriate flight parameters for the UAV that would enable reliable generation of canopy models at all stages of alfalfa growth. Flights were conducted over two separate fields on four different dates using three different flight parameters. This provided a total of 24 flights. The flight parameters considered were the following: 30 m altitude with …

Kentucky Transportation Center Research Report
Highway crashes have significant direct and indirect costs associated with them. Substantial sources of indirect costs are the congestion and delays that result from lane blockages or road closures while the crash is being investigated and the site cleared. In many cases, vehicles could be moved and roadways reopened very quickly, but this does not occur because of the need (or perceived need) to conduct a detailed investigation of the crash scene. The objective of this study was to identify opportunities to reduce the time required to investigate and clear crash scenes. This project includes a review of state and …
