Leveraging Telematics And Weather Data To Study The Productivity Of Roadside Mowers, Jijo K. Mathew, Matt Kraushar Mar 2019

Leveraging Telematics And Weather Data To Study The Productivity Of Roadside Mowers, Jijo K. Mathew, Matt Kraushar

Purdue Road School

Mowing activities are usually reported by daily work orders and it is difficult to obtain quantitative information characterizing the utilization and productivity of the mowing operations. This research uses telematics data from commercial sensors to track the daily activity of seven mowers in the Fort Wayne district. Weather data from NOAA was also captured to estimate the weather related delays. During a one-month period, the mowers collectively covered a total of around 1170 miles and an area of nearly 1800 acres of mowing. Crews worked alternative work schedules with extended hours four days a week. On an average 9.5 hour …
