Traffic
sensors or traffic light sensors are devices which are used to manage
inconsistent traffic flow efficiently. Traffic sensors also detect if
cars have entered turn lanes, cars have arrived at intersections, or
cars are stacked at intersections. Usually in large cities, traffic flow
is dictated by traffic lights with the help of timers; but traffic
signal sensors are majorly used in up county roads and suburbs as
traffic flow is less consistent there. There are numerous technologies
which are used in traffic sensor devices such as infrared, radar,
lasers, rubber hoses, video detection, piezoelectric and inductive
loops. Inductive loops technique is the most commonly used technique
owing to its simple structure and its advantage that it does not get
affected by weather conditions. Inductive loops are coils of wire that
are rooted under the road surface to detect changes in inductance as
vehicles pass above it. When the car stops over the buried coils, the
car’s steel material body acts as core of the induction loop and changes
its inductance. The changed inductance changes the current flowing
through the loop and it is conveyed to the sensor circuitry in order to
produce or alter the signals.

Global
government initiatives and investments to improve transport
infrastructure is the key factor expected to drive the global traffic
sensor market. The European Commission is launching innovative ways to
finance Europe’s transport infrastructure. In February 2017, EU called
for innovative transportation proposals which will be provided combined
grants up to Euro 1 billion from the private sector and public financial
institutions. A number of developing Asian countries are also taking
efforts to improve their infrastructure. The Government of Australia has
committed over US$ 70 billion to develop its transport infrastructure
for the period from 2013-14 to 2020-21. The Government of India in its
Union Budget 2017-18, has allotted US$ 4.03 billion for PMGSY (Pradhan
Mantri Gram Sadak Yojana) and US$ 9.55 billion for NHAI (National
Highways Authority of India) projects. Growth of urban population and
increasing need for real-time traffic information systems are also
likely to boost the global traffic sensor market over the forecast
period. Increase in urban population puts strain on traffic management
which demands efficient traffic management solutions and is expected to
boost the adoption of traffic sensors in the coming years. Even though
high costs associated with installation and management of traffic
sensors could be the limiting factor for market growth, nonetheless,
analytics-based transport solutions which uses deep analytics platforms
and cloud-based big data, presents huge opportunity for market growth.
The
global traffic sensor market is segmented on the basis of type,
application, and region. On the basis of type, the market is subdivided
into infrared sensors, inductive loops, LiDAR sensors, piezoelectric
sensors, magnetic sensors, radar sensors, thermal sensors, acoustic
sensors, thermal sensors, and image sensors. Radar sensors which are
used in integration with Wi-Fi can provide vehicle and traffic
information correctly up to 95% and its performance does not get
affected by fog, dirt, smog, sandstorms, wind, sunlight or extreme
temperatures.

Based
on application, the market has been divided into traffic monitoring,
automated tolling (e-toll), vehicle measurement & profiling and
others. Geographically, the global traffic sensor market is segmented
into North America, Europe, Middle East & Africa, Asia Pacific, and
South America. Asia Pacific (APAC) is expected to be the significant
contributor to market growth over the forecast period owing to efforts
made by regional governments to improve the transportation industry,
implement traffic management solutions, and implement e-tolls.
Some
of the key players in the global traffic sensor market are Kapsch
TrafficCom AG, EFKON GmbH, International Road Dynamics Inc., TransCore,
Kistler Group, TE Connectivity, FLIR Systems, Inc., Q-Free ASA, SICK AG,
and SWARCO AG.
