San Diego’s Smart Streetlights

From IEEE Spectrum:

San Diego’s network of smart streetlights, which has been rolling out since early 2018, continues to grow. To date, some 2,000 of the sensor-laden devices have begun gathering pictures, sounds, and other data.

So far, the city has focused on the image data, using it to count pedestrians and cars as they move around the city. This data is only just starting to feed into the way the city designs and manages traffic flows, and any consumer applications remain far in the future, says Erik Caldwell, the city of San Diego’s interim deputy chief operating officer for smart and sustainable communities. Officials are still talking through all other possible applications, such as using the streetlights to locate gunshots, track airport noise, or monitor air quality.

The amount of data generated over time will be enormous and San Diego seems to be doing a bit of experimentation to see what kind of applications they can build around that data. And they aren’t alone, Atlanta, Georgia is also embarking on a pilot program to install smart streetlights.

One downside is the maintenance that will be involved with such sensors. Streetlights are important safety devices for cities but if the “smart” piece of them is not reliable over time or through storms, the upkeep might be their downfall.
