Smart technologies are used by city governments all over the world for traffic management. These solutions are saving billions in infrastructure costs while improving safety and reliability for citizens.

Smart technologies can help reduce traffic congestion by utilizing the latest Internet of Things technology to optimize traffic flow. These systems use a combination of hardware, cloud technology and software to dynamically adjust traffic signals, freeway onramp meters, bus-rapid transit lanes, highway messages boards and speed limits.

Intelligent traffic light systems can adjust the lengths for green and red signals to maximize efficiency while protecting pedestrians, cyclists and other road users from collisions. They can also alert drivers to pedestrians, other road users and emergency vehicles.

These systems can react quickly and efficiently to changes in traffic patterns. They reduce wait times at intersections, and they also reduce fuel consumption and vehicle emission. These sensors and cell technologies can be incorporated into existing or new infrastructure.

Adaptive control of traffic can also help improve air quality. It reduces engine emissions and energy usage caused by idling. This is achieved by using a combination of data from cameras, sensor networks and cellular technology to dynamically adjust traffic lights, entry alarms and express bus lanes.

Connectivity is key to ensuring that all this information can reach its intended location. It must support large quantities of data, with ultra-low-latency and 100% availability.
