Smart technologies are increasingly being used to manage traffic in cities around the world. These solutions are saving billions in infrastructure costs while improving safety and reliability 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 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 lights can adjust the length of green and red signals in real-time to maximize efficiency and protect pedestrians and bicyclists from collisions. They can alert drivers to pedestrians and road users. They also give emergency vehicles priority access.
These systems are able react quickly and effectively to changing traffic patterns. They also reduce waiting times at intersections, as well fuel consumption and vehicle pollution. These sensors can be easily integrated into any existing or future infrastructure.
Adaptive Traffic Control can also improve the air quality by reducing engine emission and energy consumption due to 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 all of this information is able to reach its intended destination, network connectivity is essential. It must have high bandwidth, ultra low latency, and 100% reliability for the large volumes of data needed for traffic-management solutions.
