Analyzing Video And Isobus Data To Understand Risk And Safety Practices For Roadside Mowing, Nathan Sprague, Timothy Wiegman, J. T. Evans
Analyzing Video And Isobus Data To Understand Risk And Safety Practices For Roadside Mowing, Nathan Sprague, Timothy Wiegman, J. T. Evans
Graduate Industrial Research Symposium
In Indiana, roadside mowing covers 11,200 miles, presenting significant risks. The Indiana Department of Transportation (INDOT) seeks safer methods, including automated evaluations and autonomous robots. Analyzing 120 hours of video and ISOBUS data, we quantify mower interactions with the road and obstacles, finding mowers on -road up to 91% of the time in rural areas and 57% on highways. Key obstacles identified include signs and posts. This research aids in developing risk assessment models and safety evaluations, aiming to improve mowing safety and efficiency, and it supports future development of autonomous mowing technologies.
