Research And Development Services And Related Consultancy Services - Research Project - Dzsf - Investigation Of The Acoustic Effect Of Piping As A Warning In Rail Traffic. A Rail Vehicle Has A Limited Selection Of Reactions To Security -Critical Situations In The Company. The Activity Of The Signal Horn And Thus The Warning Of People Has A Major Impact On The Chances Of Survival In The Danger Area. The Perceptibility Of The Signal Horn By A Person Has Not Been Sufficiently Examined And Represents A Knowledge Gap. The Large Number Of Different Parameters, Such As The Immediate Environment, Weather Conditions, Etc., Make A Well -Founded Evaluation Of Perception. The Few Existing Examinations Therefore Show And, Due To Different Model Assumptions, Deviating Results. At The Same Time, The Superfluous Use Of The Signal Horn Leads To The Load On The Environment. From The Current State Of Knowledge, It Cannot Be Derived In A Well -Founded Manner When And With What Probability The Warning Tone Of A Signal Horn Is Perceived Depending On The Distance And Other Parameters Of People. This Knowledge Gap Plays U. An Important Role In The Future Automation Of Rail Vehicles. A Quantitative Basis Is Missing So That A Technical System Can Make The Decision On A Regular Basis Whether An Acoustic Warning Can Be Perceived In Dangerous Situation.
