Revision 2

image of SIGNI - Signs and Signals for Inland Waterways
Signs and Signals for Inland Waterways (SIGNI) establishes a harmonized signaling system, applicable to the inland waterways of international importance and coherent with the maritime buoyage system. SIGNI covers buoyage and marking of the waterways, marking of permanent structures, blockage of the waterways, waterway signs and marking for prohibited or resticted zones.




The very first resolution adopted by the Working Party on Inland Water Transport (SC.3) of the United Nations Economic Commission for Europe (UNECE) was Resolution No. 1 of 28 August 1957 on the Standardization of Signalling Systems on Inland Waterways (documents TRANS/195, annex 2 and TRANS/325). The provisions of the annex to the Resolution were later amended by Resolution No. 16 of 1975.
