Welcome to the SHADO!

Introduction

Welcome to the Simulator of Humans and Automation in Dispatch Operations (SHADO)! This tool, designed by Duke University researchers, simulates the workload of a dispatch operator and associated freight rail operators across the duration of a given shift. With SHADO, you can choose a trip with unique conditions and then see the operators' average workload after thousands of similar shifts.

You should use this tool to answer the following questions:

When are my operators over or under-utilized at work?
Why are my operators over or under-utilized at work?
How might we improve operator workload, as well as overall system efficiency and safety?

Background

A core set of tasks has been defined and implemented to encompass tasks that crew members may encounter during their trip. These tasks and their descriptions are summarized below. To see more underlying assumptions, visit advanced settings.

Task Type Description

Communicating Filtering through relevant information for the operation and communicating information that may impact the macro-level network of operations
Exception Handling Attending to unexpected or unusual situations that must be handled in order to continue with the trip
Paperwork Reviewing and recording operating conditions
Maintenance Of Way Interactions Maintaining situational awareness of other crews along the track
Temporary Speed Restrictions Recalling information issued on track bulletins and adapting to updates while train is in motion
Signal Response Management Maintaining attentiveness to direction from track signaling system and responsive to proper control system within a safely allotted time
Monitoring Inside Maintaining attentiveness to informational displays and to engineer's performance to maintain a safe operation
Monitoring Outside Maintaining attentiveness to warnings and environmental conditions that may affect operations
Planning Ahead Maneuvering locomotive control system for throttle, braking and other subtasks like horn-blowing before railroad crossing
