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 use a variety of hardware, computer software and cloud technologies to dynamically alter traffic lights and other elements such as freeway on-ramp metering, bus rapid transit lane, highway message boards, and speed limit signs.
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 react quickly and efficiently when traffic patterns change, reducing waiting times at intersections and reducing fuel consumption. These sensors can be easily integrated into any existing or future infrastructure.
Adaptive traffic controls can also improve air-quality by reducing the emissions and energy consumed by cars that are idling. 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.
Connectivity is key to ensuring that all this information can reach its intended location. It must have high bandwidth, ultra low latency, and 100% reliability for the large volumes of data needed for traffic-management solutions.
