A delicately interwoven system of processes, smart technology for traffic aid transport personnel motorists, commuters and drivers improve efficiency and flow 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 aid in forecasting changes in traffic demand and provide a variety of live information to road users.
A good example is the adaptive traffic signal system in Pittsburgh. When Carnegie Mellon University (CMU) professor Stephen Smith installed his first couple of traffic signals, which were merely experimental, in the heavily congested area of the city’s East Liberty, he saw immediate results. Drivers drove 25 percent further and spent 40 percent less time in traffic jams than before.
The system collects https://technologytraffic.com/2022/11/02/top-free-traffic-simulation-software-list/ information from sensors that are monitoring the traffic flow and adjust their timings in real-time, as well as detecting pedestrians in intersections and allowing them time to traverse the street. The sensors then transmit their raw data to a central location where it is processed by artificial intelligence and then distributed back to the intersections using 5G-enabled cell networks.
These intelligent systems also permit better, more accurate modeling of risk-reducing scenarios that a human traffic manager would not be able to achieve and all in real-time. This is a major step towards Vision Zero, the goal of a road with no accidents where humans and vehicles are able to travel together without collision.
