The company which manages ComEd smart meters and Chicago Street Lights is called Itron. They have infrastructure to manage meters and ensure uptime to ensure there is no waste in infrastructure systems.
Itron has been making strides in transforming city and utility company infrastructure to become smart and adaptable. They have teams around the world to ensure uptime of all the sensors and networks.
This company is the missing link when it comes to adapting cities to the modern connected era. Soon Itron smart traffic signals will be talking to cars and adapting to real time conditions.
I estimate real time traffic algorithms adjusting traffic lights are about 5 years away in every major American city.
In Paris they have started to implement smart traffic lights and use Itron.
I expect you to hear more about Itron as cities around the globe have a need to implement technology across their grid.
