Norwich Union has set the ambitious target of tracking 100,000 vehicles using global positioning systems (GPS) following last month’s launch of its Pay As You Drive (PAYD) product.

Speaking exclusively to Computing, the insurer said the innovative combination of technology underlying the scheme will ensure that it remains ahead of competitors keen to follow in its footsteps and adopt satellite tracking technology.

Norwich Union’s head of PAYD Kay Martin says other insurers are already looking at satellite tracking.

‘This is not a bad thing because it validates our use of the technology, but it took a long time to develop and is very complex,’ she said.

Martin says Norwich Union encountered a number of challenges in combining the front-office and back-office technology.

A black box unit the size of a CD, provided by Trafficmaster, is installed in the boot or under the dashboard so it cannot be disturbed or tampered with.

‘Each unit has a unique ID and catches journey data at one-second intervals,’ said Martin. ‘In the pilot alone, we generated 40 billion rows of data, so it is a huge exercise.’

The data is gathered using GPS and stored in the dashboard unit until it is transmitted via GSM to a purpose-built, 100TB data warehouse developed by supplier Teradata.

The data is compressed, correlated, analysed and journey information is processed each month. A billing engine supplied by Intec uses this information to create an itemised bill combining a flat-rate fee and variable fee determined by road usage.

An integrated hub developed by Smart421 acts as a communications interface and allows the various systems to communicate with each other.

‘We have been looking at this technology for about six years and have pi l oted it for more than a year to ensure that we could collect the necessary data for billing accuracy,’ said Martin.

The scope of the challenge faced by Norwich Union was revealed recently when Transport for London (TfL) ruled out satellite tracking for congestion charging because back-office functions such as billing were still prone to error.

While improvements were made in tracking, with the average location error dropping from 9.7 to 6.7 metres, TfL’s billing systems still had average error rates of 0.86 per cent.

Jenny Lau says that Norwich Union has pioneered satellite tracking for the insurance industry and is likely to be followed by other organisations.

‘Satellite tracking for insurance is likely to become much more widespread because customers are demanding transparency and this technology accommodates that,’ she said.

‘But it is important that it is tested before it is rolled out to the masses. Norwich Union piloted this for two years because it involves integration of a wide range of technologies. Getting the back-end right is vital.’
