Abstract:This report documents the results of a cognitive task analysis (CTA) that examined the cognitive and collaborative demands and
activities of railroad roadway workers. The purpose of the CTA of roadway workers was to understand the factors that complicate
performance in today’s environments, as well as the knowledge and skills that roadway workers have developed to cope with the
cognitive and collaborative demands placed on them.
The results revealed numerous activities that railroad workers engage in that improve overall efficiency of railroad operations and
enhance roadway worker safety on and around the track. These include cooperative activities within and across crafts, including
dispatchers, train crews, and roadway workers. Some of these activities are codified in formal operating rules. Others have
developed informally. The results point to the potential benefits of introducing portable digital communication systems with
global positioning system capabilities and suggest specific design recommendations. The results also suggest potential benefits of
implementing positive train control systems for enhancing roadway worker safety.
