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

Future Of The Mutcd, Steven G. Jewell P.E., Ptoe
Purdue Road School
The current edition of the national MUTCD was published in the Federal Register as a final rule in December 2009, effective on January 10, 2010. Most people probably don’t realize that this major tool of our trade is a living document that is under constant review and revision. The MUTCD is legally produced and maintained by FHWA. It usually gets officially revised and republished about every 6-10 years. There are a lot of legal issues and hoops that FHWA must progress through, including public review and documentation, to republish the Manual. Because of the constant changing and improving technology, FHWA …
