Development of a Model for Truck-Cab Design Based on Operator Task 740273

A methodology has been developed which is capable of generating design criteria for truck-cab control and display elements. The method combines driver behaviors determined by a task analysis with graphic theories of system interactions to analyze the influences of cab design features on safety-critical driver behavior. The end product of the method is a series of control and display categories, each containing the desirable design criteria of the category elements. All criteria and categories are assigned weighting factors to be used during “hard design” tradeoffs.
