Intelligent Transportation System- The New Living Innovation!
Intelligent Transportation System
Intelligent
transportation system (ITS) is a complex application that strives to deliver
novel services related to various modes of transportation and traffic
management, allowing users to be better informed and make safer, more
coordinated, and 'smarter' use of transportation networks.
Some of
these technologies include emergency call-outs in the event of an accident, the
use of cameras to police traffic regulations, and signs that indicate speed
limit changes based on conditions.
What Are the Intelligent Transportation Technologies?
The technologies used in intelligent
transportation systems range from basic management systems like car navigation,
traffic signal control, container management, variable message signs, automatic
number plate recognition, or speed cameras, to monitoring applications like
security CCTV systems, automatic incident detection, or stopped vehicle
detection systems, to more advanced applications that integrate live data and
feedback from a variety of other sources. Predictive approaches are also being
developed to enable sophisticated modelling and comparisons with previous
data. The following sections go through some of these technologies.
Wireless Communications:
Wireless communications technology in
many kinds has been proposed for intelligent transportation systems. Within
ITS, radio modem transmission on UHF and VHF frequencies is commonly used for
short and long-distance communication.
IEEE 802.11 protocols, notably WAVE or
the dedicated short-range communications (DSRC) standard established by the
Intelligent Transportation Society of America and the United States Department
of Transportation, can be used for short-range communications of 350 metres.
The range of these protocols can theoretically be expanded by deploying mobile ad
hoc networks or mesh networking.
Infrastructure networks, such as 5G,
are used for longer-range communications. These intelligent transportation technologies are
well-established for long-range communications, but unlike short-range
protocols, they need considerable and expensive infrastructure development.
