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 are able to reduce traffic congestion and improve safety by using the Internet of Things. These systems integrate a range of hardware, software and cloud technology to dynamically adjust traffic lights, freeway on-ramp meters, bus rapid transit lanes, highway message boards and speed limits.

Intelligent traffic lights adjust the length of the green and RED signals in real-time for maximum efficiency and to protect pedestrians and cyclists against collisions. They can alert drivers to pedestrians and road users. They also give emergency vehicles priority access.

These systems can react quickly to changes in traffic patterns. They can reduce waiting times at intersections as well as fuel consumption and vehicle emissions. These sensors and cellular technologies can be integrated 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 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.

To ensure that this data can reach its destination, network connectivity will be essential. It must provide high-bandwidth, ultra-low latency and 100% reliability to support the large quantities of data that are needed for traffic management solutions.
