14000 street lights How to turn San Diego into America's smartest city

Nov 27, 2018

Santiago announced last year that it was building the world's largest smart city IoT platform and using CITYIQ Solutions developed in partnership with General Electric (GE) to improve parking, transportation and public safety on city streets. 

The Cityiq solution is an intelligent urban digital infrastructure launched by GE and based on Intel technology that provides sensors (or "smart nodes") that can be installed on street lights.  

More recently, the city has pledged to add 1000 additional CITYIQ sensors, as well as an interface to the lighting control utility, to increase the efficiency of LED street lamps by 20%.  

San Diego is adding application packages to its 4,200 Cityiq smart nodes from GE All in all, the project's massive digital infrastructure will include 4,200 new CITYIQ sensors (3,200 planned last year), which are installed on 14000 LED street lights. Build your own urbanized Internet of Things (IoT) by carrying Intel Atom processors, cameras, microphones, Wi-Fi, Bluetooth, acoustic sensors, and CITYIQ sensor nodes that measure temperature, air pressure, humidity, and even magnetic fields on street lights. 

Some of the collected data is uploaded to GE's Predix cloud via the AT&T LTE network. 

The plan is expected to save the city 3.6 million of dollars a year in energy and maintenance costs. GE is currently working with the U.S. data operator AT&T, Intel, to develop the project. As a data operator, AT&T provides a highly secure and reliable networking service. 

Intel IoT technology delivers advanced computing power, processing power, and edge analysis capabilities to help extract metadata and integrate with sensors through secure cloud connectivity. 

Lighting control Utility for urban applications The CITYIQ system collects real-time data while supporting a large number of Open data APIs and smart city applications, which will help address some of the city's challenges, including the Office of Economic Development, 

Several urban departments, including the San Diego Police Department and the Transportation Engineering and Operations department, are already using CITYIQ data to improve traffic flow and pedestrian safety, as well as to achieve new public services. 

For example, increased computing power allows street lights to help drivers optimize their travel routes, find open parking spaces, and even inform traffic enforcement when vehicles are parked illegally. 

Austin Ashe, general manager of current's smart city, said it was only the beginning because most of the data collected by the street lighting Internet of Things (IoT) network would be released publicly, and the city allowed and encouraged software developers to use the data to build applications to help local residents and visitors. Applications that currently appear include apps that identify the quietest walking routes (for people who want to have a conversation while strolling); "Digital cane" apps designed to use traffic and location data to help visually impaired people cross the road; and the history of high-frequency pedestrian crossings; and ways to identify interesting events in real time, 

Find hotspots by tracking the way pedestrians gather or move forward. The lighting network can also receive the city's existing ShotSpotter network, which automatically locates sources and monitors sound in real time, and many municipalities use ShotSpotter to improve the efficiency of law enforcement. 

And the increase in smart street lights could increase the coverage of ShotSpotter from 10 square kilometres (about 4 square miles) to a wider area.   

Street lights can use a network of sensors deployed throughout the city to alert police to dangerous situations by identifying broken glass or the sound of car crashes; Through a shooting detection app, more than 90% of shootings can be captured in less than a minute with accurate location information to help emergency services.  

Austin Ashe, GE's current general manager of Smart cities, says the way the app and Cityiq together, as the app Store does for smartphones, can save the city time and money-generating entrepreneurship, creating jobs, generating revenue and solving problems. Santiago is said to now have the world's largest network of urban street lighting IoT sensors, involving public and private sector cooperation such as GE,AT&T and Qualcomm. 

The city continued to strive to operate the city intelligently, not long ago won the 2018 Smart 50 award. It all started with San Diego starting to replace some streetlights with smart street lights.
