A Discussion Paper :: Employing GPS and Line-Of-Sight Proximity Detection technologies to deliver an accurate, cost-effective, 'advertiser-credible' audience measurement service to the Australian Out-Of-Home Advertising Industry



The lack of measurable audience metrics for out-of-home advertising, is considered by many to be a major obstacle to the industry. 

Based on the assumption that we can't manage what we can't measure...it is proposed that if advertisers were provided with an accurate and credible audience measuring mechanism for Out-of-home media (something akin to the television or radio ratings survey system), advertisers (and their agents) may be more predisposed to invest in Out-of-home media. Indeed in a recent Online Survey, over 100 advertisers and agents suggested that they believed that 'the right audience measurement tools' would foster an industry-wide ad revenue growth of between ten and fifteen percent!

The Out-of-home People-meter Project is offered as a possible, economically-sustainable option to consider for this purpose.

Brief Summary of The Out-of-home People-meter Method::

Step 1 :: Out-of-home sites (external, internal, fixed and mobile plant) are equipped with what is called a 'TOP Gun'...a simple miniature, low-powered, low-cost RF transmitter (using similar technology to a remote control for garage doors, etc). These TOP Guns can be configured to cast a 'broadcast field', closely approximating the 'viewable field' of the media they're attached to (e.g. the TOP Gun attached to a Supersite might cast a broadcast field of 150m in one direction down a highway, where the TOP Gun on a Taxi-back might only throw a broadcast field of 10 to 15m in a 110 degree arc directly behind the taxi that is carrying it, etc.) Each TOP Gun continually transmits only two 'bytes' of information...the first containing the unique ID Key number of the site/plant it represents and the second contains an ongoing universal time-code (date and time).

Step 2 :: Survey participants are provided with a wearable receiver (a TOP Watch) that not only records any Line-of-sight proximity encounters with a Top Gun, but also constantly monitors the exact location of the survey participant via GPS (Global Positioning Satellite) data.  The combined data from the TOP Watch, accurately records and verifies any legitimate opportunity* for a survey participant to 'view the Out-of-home advertising materials' they encounter. Collectively, this data will be correlated with the demographic statistics of the survey participants and accurate 'reach and frequency' demographics are extrapolated for the region/territory being surveyed. (Statistically, this is the same process that is employed by the television and radio industries in the establishment of 'people-meter' and audience rating surveys.)

[* Clearly, this process doesn't measure whether the survey participant actually 'viewed' the advertising media --- that's what the 'Qualitative measurement' in Step 3 (below) is for. All Step 2 of the process does, is accurately record whether the survey participant had a 'legitimate opportunity to view the advertising media'. We should point out that the industry-accepted 'television rating surveys' don't record whether someone actually 'viewed' an advertisement either. They too (like the proposed TOP Watch Ratings) only estimate the size and demographics of the potential audience that has a legitimate opportunity to view the advertisement...based on the observed and measurable behaviour of a small but well-defined sample of the total population. At least the TOP Watch system requires actual 'line-of-sight'...meaning for example, that if a large truck were to obscure the view of a Supersite from a survey participant travelling down the highway (or to define it more accurately, if a large truck were to obscure the transmission of a TOP Gun attached to a Supersite from being detected by a TOP Watch worn by a survey participant travelling down the highway), then a 'hit' would NOT be recorded. Only legitimate 'line-of-site' proximity detections are recorded. In this way, the TOP Watch system is a conservative and realistic measurement of 'actual' opportunities to view the advertising media.]

Step 3 :: At least once during each survey period, each survey participant is required to indicate on a 'qualitative scale' how well they recall viewing the Out-of-home media that they 'recently' had an opportunity to view and potentially what 'action' (if any) the survey participant intends to take in relation to those recently accessed sites. This provides an additional layer of 'qualitative data' that is effectively missing from published television and radio surveys and arms advertisers with useable intelligence on the type, location, creative and frequency aspects of successful Out-of-home media.

Conclusion :: By integrating the T.O.P. process into the existing R.O.A.M. and Cody's 'Road Reader' and GPS methods, the costs of implementing such a process could be surprisingly low, though the combined support of all stakeholders would be required if the process is to succeed in providing worthwhile, standardised audience metrics data for the entire Out-of-home Advertising industry. There is also the potential to perfect the technology in this market and export our findings internationally which could further reduce the costs involved...(after all, this IS a global problem.)

We should also point out, that much of the technology to provide this service, though theoretically available, has only been assembled in virtual models by the author and proper field testing and trials would need to be undertaken before 'Proof of Method' could be verified and decisions on hardware and software could be finalised. For this purpose, La Trobe University could be considered an independent agent.
