Development of Symbology for a Locomotive Head-Up Display (HUD)
As part of a Federal Railroad Administration (FRA)-funded Head-Up Display (HUD) research project that began in 2020, KEA Technologies Inc. developed a limited library of symbols for both freight and passenger operations, to be integrated in a prototype HUD developed separately by another team of researchers sponsored by FRA. The research team developed two surveys to collect feedback from stakeholders. Based on the feedback, the team made the suggested changes to the symbols and finalized the libraries. Three library subsets were created, one comprising all the symbols, a second comprising symbols only relevant to passenger operations, and a third comprising symbols only relevant to freight operations.
