Smart technologies for traffic are a technologytraffic.com/2021/12/29/generated-post-4/ delicately woven system of processes that aid transport workers, drivers, and commuters regulate the flow and efficiency of traffic. Utilizing advanced IoT sensors, hardware, routers and cellular technology smart traffic systems can modify control mechanisms in a dynamic manner, such as traffic lights as well as freeway on-ramp meters bus rapid transit lanes highway message boards and even speed limits. They can also assist in forecasting shifts in traffic demand, and provide a variety of live information to road users.

A good example is the adaptive traffic signal system in Pittsburgh. Stephen Smith, a professor at Carnegie Mellon University’s (CMU) He installed his first experimental traffic signals in the heavily congested part of East Liberty in the city. Smith saw immediate results. Drivers traveled 25 percent farther and spent 40 percent less time idling.

The system collects data from sensors that track incoming traffic and adjusting their timing on the fly and also detecting pedestrians at intersections and allowing them time to cross the street. The sensors send their raw data to a central hub where it’s processed by artificial intelligence and then sent back to the intersections via 5G-enabled cell networks.

These intelligent systems also provide better, more accurate simulation of risk-reducing scenarios that a human traffic controller could not achieve and all in real time. This is an important step toward Vision Zero, a goal of safe and secure driving in which motorists and pedestrians share the road with no collisions.
