Harrisburg expands streetlighting into broad smart city project


The City of Harrisburg in the US state of Pennsylvania is testing smart city technologies to improve services to its residents.

The city had in 2016 partnered with Telensa to install an IoT communications network to connect some 4,000 smart street lights. The project reduced the city’s utility bill by 60-70%

The IoT network will now be used to connect smart sensors for traffic, air quality and waste monitoring.

The city is deploying technologies including CA Traffic for traffic analytics, Libelium for air quality and FarSitefor waste monitoring.

Data acquired from the sensors is analysed and combined with existing lighting data and displayed in a single smart city dashboard.

This allows  correlations across departments and smarter, more efficient and joined up services.

Harrisburg is also set to test the use of technology for Traffic Adaptive Lighting, whereby groups of streetlights can be dynamically adjusted in the central management system using real-time, raw traffic data received from a radar-based sensor. This adaptive lighting results in energy savings of up to 30%.

Wayne S. Martin Esq., Harrisburg’s City Engineer, said: “We live in a data-driven world, but we’re not going to monitor stuff just to monitor it – it has to make sense to the city!

“That’s why we have chosen these smart city applications to open up endless possibilities for us to improve city efficiency and save money – the dollars can really add up.”
