Smart Technologies for Traffic
Smart technologies for traffic are a delicately interwoven system of processes that aid transport personnel, drivers, and commuters regulate the flow and efficiency of traffic. Utilizing advanced IoT hardware, sensors routers, cellular technology and sensors, intelligent traffic systems can adapt control mechanisms dynamically, like traffic lights, freeway on-ramp meters, bus rapid transit lanes, highway message boards and even speed limits. They also assist in forecasting shifts in traffic demands and provide a variety of real-time 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 the heavily congestion-ridden area of East Liberty in the city. Smith saw immediate results. Drivers traveled 25 percent more efficiently and spent 40 percent less time idling.
The system works by collecting information from sensors that are monitoring the traffic coming in and then adjusting their timing in real-time and also detecting pedestrians at intersections and giving them enough time to cross the street. The sensors transmit their raw data into an centralized hub, where it is processed by artificial intelligence. The data is then transmitted back to the intersections through 5G-enabled cell networks.
These systems can provide better and more accurate modeling of scenarios that minimize the risk that a human traffic manager cannot achieve. And all this in real-time. This is a major step towards Vision Zero, the goal of a safe road that ensures humans and vehicles are able to travel together without colliding.
