The core idea around smart cities is to use technology to improve efficiency. That means taking all of the technology advances that have been applied towards things like video streaming, photo sharing, and advertising and bringing them to bear on things like city planning, public health and safety, education, and transportation.
The technology to make massive advances in these efforts already exists today. Here are a few examples:
- All street light and traffic light infrastructure along with telephone and electricity poles can be networked and sensors can be installed.
- The sensor network can publish real time traffic data to an open API, allowing for Waze/Google Maps to direct traffic flows better.
- Parking monitoring can be automated, i.e. an open API where anyone can pull info on where open parking spots are.
- Sensors can tell us when there is excess (or lack of!) electricity or water consumption, alerting the utility company of potential equipment failure or a safety issue.
