Smart technologies for traffic are a delicately woven system of processes that aid transport workers, drivers, and commuters manage the flow and efficiency of traffic. Utilizing the latest IoT hardware, sensors routers, sensors and cellular technology, intelligent traffic systems can automatically adjust control mechanisms such as traffic lights, freeway on-ramp meters bus rapid transit lanes, highway message boards and even speed limits. They can also forecast changes in traffic demand, and provide real-time information to road users.
Pittsburgh’s adaptive traffic signal system is an excellent example. Stephen Smith, a professor at Carnegie Mellon University’s (CMU) was the one who installed his first traffic signals to a heavily trafficked area of East Liberty in the city. He noticed immediate https://technologytraffic.com/2022/07/25/start-using-a-virtual-data-room-today-to-save-time-money results. Drivers drove 25 percent further and spent 40 percent less time in traffic.
The system collects data from sensors that track the traffic flow and adjust their timing on the fly, as well as identifying pedestrians near intersections and giving them enough time to traverse the street. The sensors send their raw data to a central center where it is processed by artificial intelligence and then sent back to the intersections using 5G-enabled cell networks.
These advanced systems also enable better, more precise modeling of risk-minimizing scenarios that a human traffic controller could not accomplish – all in real-time. This is a major step towards Vision Zero, a goal of safe driving where humans and vehicles share the road without collisions.
