Does the ‘In-cab coach’ work in practice?
This was a key question behind a recent white paper “The impact of immediate feedback on driving behaviour’ published by Masternaut in June 2017.
The paper summarises the results of a study of 9,000 light commercial vehicles (LCVs) in commercial fleets comparing vehicles with the in-cab coach to vehicles without it over three months.
Data was compiled on the following driver behaviours:
- Harsh driving events
In addition, data on fuel consumption was also monitored and analysed.
The results were unambiguous.
Overall, the vehicles equipped with the In-cab coach showed a substantially lower rate of speeding events than those without. In fact, the average number of speeding events recorded per 100 miles travelled was 53% less than the that recorded by the LCVs without immediate feedback.
This is a dramatic effect and can only be seen as a notable modification in driver behaviour that undoubtedly leads to significant improvements in safety. At which point, it’s worth remembering that speed is an incredibly important element in overall safety levels. In the UK, over 3,000 people lost their lives in road traffic incidents where speed was a contributory factor. Speed is also correlated to injury levels and to the financial impact of road collisions.
And it has a profound impact on fuel economy, where fuel efficiency levels fall off dramatically with increasing speed. Managing speed is thus a ‘very good thing’ and the impact of immediate feedback via the In-cab coach should be seen in this context.
But it also affects other driving behaviors:
- Harsh driving events are also considerably lower in vehicles with the In-cab coach, with the number of events recorded per hour down by over 25%
- Idling times are also lower, with equipped LCVs showing idling time as 7.5% of total driving time against the 9% figure shown by those without the In-cab coach
And finally, immediate feedback also has an effect on fuel consumption, with over 5% savings achieved across all types of LCV equipped with the In-cab coach.
