In
yet another success for the Internet of Things (IoT) technology, a team of US
researchers has developed a system to ease vehicle-to-infrastructure and
vehicle-to-vehicle communications for better traffic management and curb
increasing road accidents.
The
team led by Larry Head from University of Arizona used optimisation and
algorithms with wireless devices and traffic signal controllers to manage the
traffic signals in the US city of Phoenix, according to latest reports by
zeenews.india.com.
"Drivers
communicate wirelessly on smartphones with people around the globe, but their
cars cannot communicate with cars around the corner. That is about to
change," Head said.
The
researchers a took a team of supervisors, locals and transportation officials
on a test bus ride on a 2.3-mile stretch of a road in Anthem -- a suburb in
Phoenix.
The
road had "Dedicated Short Range Communications" (DSRCs) radios
mounted in demo
buses and emergency vehicles, atop light poles and in roadside
equipment boxes at intersections.
Along
the test ride, the bus received messages from traffic signals, computed how
long it would take to reach the signals and sent requests for service back to
the signals.
Using
the algorithms developed by Head's team, the signals prioritised approaching
vehicles: passenger, transit, emergency and commercial.
For
example, at one intersection, path was cleared for a fire truck and got the
green light first. The monitor also alerted the bus of upcoming construction
and school zones.
"Vehicle-to-infrastructure
and vehicle-to-vehicle communications, or connected cars, are on the horizon --
and their capabilities will significantly change how traffic is managed and how
drivers experience the road," Head added.
