Visibility Adjustment Index (VAIs)

Visibility Adjustment Index (VAIs) ratio or the percentage of a unit’s total Opportunity to See (OTS) audience (circulation) who are likely to notice an outdoor ad. VAI’s are derived from Geopath’s visibility study. The impact of common board characteristics, size, road side, distance from the road, road type, and illumination are taken into consideration. VAIs are not measures of audience.
