Analysis on Google Maps allowed us to calculate that delays from London to Birmingham (M6) increase average journey times from two and a half hours to four hours on weekday peak times and just over three hours on weekends.

From London to Leeds (M1) we found the average journey time to be three and a half hours, increasing to five hours at midweek peak and four and a half on the weekend.

This analysis also showed us when people would be experiencing their worst delays and their worse car journeys.

These motorways can be a nightmare for drivers and we needed to capitalise on these moments of frustration.

We would target them one journey at a time. We would isolate our activity to the two routes which offered the best opportunity - Leeds and Birmingham - because they ran along two of the worst motorways in Britain.

Our ambition was to adapt our radio copy in real time as people drove along the motorways - stuck in traffic jams – getting a different message relevant to their location. The problem is, radio is sold by TV region, making that practically impossible.

So, we broke the region up based on individual radio transmitters – eight in total – and created 64 new transmission micro regions along the motorway. No-one has ever planned, bought and created copy for radio like that before.

We then delivered bespoke copy for each 10-30km stretch of the motorway, based on time of day, day of week and around traffic blackspots. Finally, we used live Google Maps data to plan our OOH campaign. We set a threshold based on the average speed of historic traffic, and our OOH was triggered only when it was 15% below that threshold.

Shifting our strategy to targeting traffic jam ‘hell spots’ lead to significant improvements across every key metric:

Over the course of the campaign consideration for the train increased along both routes; the M6 (Virgin Trains’ London to Birmingham) route rose from 73% to 82%, while the M1 (Virgin Trains’ London to Leeds route) went from 76% to 83%.

Both the M6 and M1 routes saw a YoY increase in both journeys (+6.8% and +1.7% respectively) and revenue (+4.4% and 3.9%).

Radio delivered an ROI of 15:1 and OOH delivered an ROI of 5:1, giving the campaign the highest ROI of any Virgin Trains campaign on record.
