RFC: Design of a new tag for marking a railway crossing with additional sound signaling for the blind in the Czech Republic

Crossing the tracks at a level crossing is a particularly dangerous activity without a visual inspection.

The building regulations take this into account and require that when establishing or reconstructing such a crossing located in a village (i.e. in an urban area), possibly connecting two residential zones or on a route frequented by pedestrians, acoustic signaling for the blind should also be taken into account.

Acoustic signaling is activated by command number 5 of the VPN-type radio for the blind

acoustic beats meaning stop are slow, with a frequency of about 1.5 Hz, a beat frequency of about 8 Hz means free. To distinguish it from signals at a pedestrian crossing at an intersection, the tone frequency of the acoustic beats at the crossing is about 1000 Hz, in contrast to crossings, where we hear either a characteristic “knock” or a beep with a tone frequency of about 500 Hz.

The source of the sounds just described is located on the same pole, on which are located two alternately flashing red lights for other road users.[1]
