When the Oregon Department of Transportation decided to transform their maintenance truck fleet into a multi-purpose fleet they needed to address the variation in cab designs in order to fit the new set of controls.
ODOT Fleet Management contacted the School of MIME for assistance through a Capstone Design project. The Capstone students, under the supervision of Dr. Javier Calvo-Amodio, designed a systematic method to identify the best baseline cab characteristics in accordance to ODOT’s specifications and based on safety, performance and comfort of the operator.
As a solution, the team developed the Cab Analysis and Scoring Tool (CAST) system.
The CAST system is basically a scientific ergonomic tool to compare truck cabs. Using it, ODOT fleet management, and others, can evaluate and select best truck cabs for their needs.
The CAST consists of two sections: the Cab Analysis Tool (CAT) and the Cab Scoring Tool (CST). The CAT is a set of standardized instructions on data gathering that guides a user through the steps of systematic measurements of a cab. These measurements are then entered into the CST to calculate the ergonomic score of the cab.
The tool has been licensed at OSU and was introduced at the Western States Highway Equipment Managers Association (WSHEMA) and will be published in an academic journal.
It is worth noting that work-related disabilities caused by musculosketal disorders (MSD) can impact roughly 30 percent of the work force aged 25-65.
MSDs consist of minor physical disabilities affecting the muscles, bones, and joints. Pain and discomfort may interfere with everyday activities to a varying degree.
A key way to mitigating costs from ergonomically induced driver-related injuries
in the United States today is the application of ergonomic standards, the
Capstone team said.
Unfortunately, within the transportation industry, the application of ergonomic standards is not commonly used. As a result, musculoskeletal disorders are one of the leading causes for on-the-job injuries.
The CAST tool has been implemented by ODOT fleet management and has been used in the process to purchase a new fleet of 10-ton trucks.
