The visibility is generally less than the rvr.

The methods for measuring rvr and prevailing visibility are quite different rvr is measured in a specific direction usually using transmissiometers while the prevailing visibility will be the average and if less than 1500 m the minimum value in a specific direction this means that there can be no direct comparison and rvr is likely to be the same as or greater than the lowest reported value of prevailing visibility
