Norfolk County Council is expecting 90 per cent energy savings from low-power real-time passenger information (RTPI) signs it is installing at bus stops and shelters in Norwich and Great Yarmouth.

The 90 per cent savings will come from conventionally mains-connected displays. There is also a zero energy-cost solar-powered version designed primarily for remote locations, where extending mains is prohibitively expensive.But the county is using them in-city, to take advantage of government Better Bus Area funding aimed at boosting urban public transport use.
Future rural rollout will depend on progress made by bus operators in equipping their fleets with GPS units to feed their location data. The signs have four weeks’ battery back-up.
Stressing the importance of cost, Mark Cartwright of the Real Time Information Group says local authority spending cuts have hit RTPI investment hard, with some councils, including Lancashire, switching off their systems. “Others have kicked their rollout and/or replacement programmes into the long grass – so there is strong pressure to look at radical, low-cost options,” he explained.
