A delicately interwoven system of processes, smart technology for traffic can help transport workers as well as commuters and drivers to manage traffic flow and efficiency. Intelligent traffic systems can adjust the controls of traffic lights and freeway onramp meters as well as bus rapid transit lanes. They also make use of advanced IoT hardware and routers as well as cellular technology and cell networks. They also aid in forecasting shifts in traffic demand and provide a variety of live information to road users.
An excellent example is the adaptive traffic signal system in Pittsburgh. Stephen Smith, a professor at Carnegie Mellon University’s (CMU) He installed his first traffic signals in a trafficked area of East Liberty in the city. He noticed immediate results. Drivers travelled 25 percent farther and were able to drive 40 percent more efficiently.
The system works by collecting data from sensors that track the traffic coming in and then adjusting their timings in real-time and also detecting pedestrians in intersections and giving them enough time to safely cross the street. The sensors send their raw data into a central hub where it is processed by artificial intelligence. It is then sent back to the intersections using 5G-enabled cell networks.
These advanced systems permit better and more accurate modeling of scenarios that reduce risk, which a human traffic manager cannot accomplish. All this in real-time. This is a major step towards Vision Zero, the goal of a road with no accidents where both vehicles and humans are able to travel together without colliding.
