City governments worldwide are turning to smart technologies for traffic management. These solutions can save billions in infrastructure cost while improving safety, reliability and security for citizens.

Smart technologies help reduce congestion through the use of the latest Internet of Things (IoT), which optimizes traffic flow and improves safety. These systems combine a range of hardware and software with cloud technology to dynamically adapt traffic lights, freeway ramp meters, bus rapid transport lanes, highway messaging boards, and speed limits.

Intelligent traffic signals can adjust the lengths of green and yellow signals in real time to maximize efficiency, and smart technologies for traffic protect pedestrians and bicycles from collisions. They can also alert drivers to pedestrians, other road users and emergency vehicles.

These systems react quickly and efficiently when traffic patterns change, reducing waiting times at intersections and reducing fuel consumption. These sensors and cell technologies can be incorporated into existing or new infrastructure.

Adaptive traffic control can also help to improve air quality by reducing engine emissions and energy consumption caused by idling, while keeping cars moving. This is done by combining data from cameras, sensors networks, and cellular technology in order to dynamically adjust traffic signals, entry alarms, and express bus lanes.

Network connectivity is crucial to ensure that this information reaches its destination. It must have high bandwidth, ultra low latency, and 100% reliability for the large volumes of data needed for traffic-management solutions.
