Smart cities usually have:
• Devices that measure traffic in real-time
• Devices that display which public parking lots and car and bicycle rental points are occupied in real-time
• Real-time geolocation of public transport vehicles
• Devices that measure how full garbage containers are to optimize collection.
• Real-time measurement of pollution levels.
• Alerts on dangers (floods, fires, storms, hurricanes) to enact the proper prevention and response mechanisms
• Urban video surveillance.
