Smart Technologies for Traffic

A delicately interwoven network of processes, smart technologies for traffic aid transport personnel commuters, drivers and drivers control traffic flow and efficiency. Intelligent traffic systems can adjust control mechanisms such as traffic lights and freeway onramp meters as well as bus rapid transit lanes. They also utilize advanced IoT hardware and routers, cellular technology and wireless networks. They can also forecast changes in traffic demand, and provide real-time 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 traffic signals to a heavily trafficked area of East Liberty in the city. He saw immediate results. Drivers drove 25 percent further and spent 40 percent less time in traffic.

The system collects data click here for more info from sensors that track incoming traffic and adjusting their timings in real-time and also detecting pedestrians in intersections, and giving them time to walk across the street. The sensors then send their raw data to a central hub where it’s processed by artificial intelligence and then sent back to the intersections using 5G-enabled cellular networks.

These intelligent systems allow for better and more accurate modeling of scenarios that reduce the risk that human traffic managers are unable to accomplish. All this in real-time. This is a big step toward Vision Zero, a goal of a safe, accident-free road in which motorists and pedestrians share the road without collisions.
