How Smart Cities Are Improving Digital Signage with IoT

Digital signage is a subset of electronic signage that can be placed in smart cities to make life easier for citizens. These digital displays use LCD, LED, e-paper, or other technology to display videos, images, menus, text, and more. While many private companies have invested in using this technology, its implementation in smart cities has proved to be very useful, especially when combined with the Internet of Things (IoT). Smart cities improving digital signage adds value to public transportation, traffic signs, and during emergencies.

IoT Digital Signage and Public Transportation

Public transportation can be confusing for locals and tourists alike, but digital signage changes that. Using IoT technologies, cities are revolutionizing interactive kiosks to help citizens to use public transportation services. Furthermore, these technologies can integrate with mobile devices, giving people information on how to get around on their phones. Imagine not getting lost on public transport or going the wrong way because the data will be directly at your fingertips. Users can always find their way and see weather or traffic alerts from the interactive kiosk information connected to their device.

Traffic Signs with Digital Signage and IoT

Cities can use this technology with traffic lights as well. By installing an IoT sensor, digital traffic signs can react and monitor traffic and change signage accordingly. Then, the traffic signage can send these readings to other interactive kiosks, which means pedestrians and drivers alike will know of congestion or alerts.


Digital Signage During an Emergency

IoT-based digital signage can help during emergency situations since interactive kiosks have Wi-Fi. Citizens can use emergency call buttons installed in the stalls connecting them to authorities or use the Wi-Fi to connect to their phones and devices. These kiosks can house city service information and emergency notifications for nearby citizens who need to stay informed.


The Cost of IoT Digital Signage

The benefits of this technology for citizens are clear, but is IoT digital signage too expensive for smart cities? New York City implemented this technology with kiosks that provide free Wi-Fi, telephone services, charging stations, and wayfinding, and it was all paid through advertising. The project is even set to make $500 million for New York City.

Advertisers clearly realize the potential of IoT digital signage, which can change depending on who walks past the sign. They can post hyper-targeted ad campaigns in real-time based on demographic features of the person passing the sign. This ability takes advertising to a new level, which is why big companies are investing heavily in this technology that genuinely benefits smart cities.
