08 Oct Smart Technologies for Traffic
A delicately woven together network of processes, smart technologies for traffic can help transport workers as well as commuters and drivers to manage traffic flow and efficiency. Using advanced IoT sensors, hardware routers, sensors and cellular technology intelligent traffic systems 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 real-time information to road users.
Pittsburgh’s adaptive traffic signal system is a great example. When Carnegie Mellon University (CMU) professor Stephen Smith installed his first couple of traffic signals, which were merely experimental, in a highly congested part of the city’s East Liberty, he saw immediate results: Drivers traveled 25 percent more efficiently and spent 40 percent less time idling in traffic jams than before.
The system works by collecting data from sensors that monitor the traffic coming in and then adjusting their timing on the fly in addition to detecting pedestrians in intersections and giving them enough time to cross the street. The sensors then transmit their raw data to a central center where it’s processed by artificial intelligent and then distributed back to the intersections using 5G-enabled mobile networks.
These intelligent systems allow for more accurate and precise modeling of scenarios that reduce risks, which human traffic managers cannot achieve. All this in real-time. This is a major step towards technologytraffic.com/2020/05/21/the-benefits-of-using-modern-traffic-technologies-by-data-room Vision Zero, a goal of safe and secure driving in which both vehicles and humans share the road without collisions.
