Research And Development Services And Related Consultancy Services – Research Project - Dzsf - Investigation Of The Acoustic Effect Of Whistles As A Warning In Rail Traffic. A Rail Vehicle Has A Limited Range Of Reactions To Safety-Critical Situations During Operation. Activating The Signal Horn And Thus Warning People Has A Major Influence On The Chances Of Survival In The Danger Area. The Perceivability Of The Signal Horn By A Person Has Not Been Sufficiently Investigated And Represents A Gap In Knowledge. The Large Number Of Different Parameters, Such As The Immediate Environment, Weather Conditions, Etc., Make A Well-Founded Assessment Of Perceptibility Difficult. For This Reason And Due To Different Model Assumptions, The Few Existing Studies Show Different Results In Places. At The Same Time, The Unnecessary Use Of The Signal Horn Puts A Strain On The Surrounding Area. Based On The Current State Of Knowledge, It Is Not Possible To Determine When And With What Probability The Warning Tone Of A Signal Horn Will Be Perceived By People Depending On The Distance And Other Parameters. This Knowledge Gap Plays, Among Other Things, Plays An Important Role In The Future Automation Of Rail Vehicles. There Is A Lack Of A Quantitative Basis So That A Technical System Can Make A Rule-Based Decision As To Whether An Acoustic Warning Can Be Heard In A Dangerous Situation.
