3. INTRODUCTION
• The existing methods for traffic management and control are
inadequately efficient in terms of performance, cost and maintenance.
• The Intelligent Traffic Signal Control (ITSC) system consist of high-
performance, low power Arduino board, RFID reader and tags, IR sensors,
loop sensors and GSM.
•The ITSC system will able to deal three basic problems of traditional
traffic light system: i) Detection of traffic volume by using genetic
algorithm. ii) Emergency vehicle detection such as ambulance, police etc by
using wireless sensor network (IR) embedded at the signal intersection. Iii)
Stolen vehicle detection, violator detection and toll tax collection
4. TRAFFIC VOLUME DETECTION
• Vehicle detection loops, called inductive-loop traffic detectors, can
detect vehicles passing or arriving at a certain point, for instance
approaching a traffic light or in motorway traffic.
• When a vehicle passes over the loop or is stopped within the loop,
the vehicle induces eddy currents in the wire loops, which decrease
their inductance which actuates circuit and detects the vehicle.
• Genetic algorithm calculates the green light time for signal
depending on the three factor’s demands, densities, and flow. The
formula to calculate the green light time is given below:
Total time = (Demands) + (Densities) + (flows)

7. USING RFID TAGS
•Here, we use RFID tags, which are embedded in the vehicles, at the time of number
plate assignment by RTO office.
• When the red light is ON, the RFID tag is read by the reader(installed in traffic
poles/toll booths )
• Succeeding this, the reader which contains the details of the driver e.g. location,
contact no. and email id, will send this info to base station which will then send
message and email to the vehicle owner regarding license confiscation with the aid
of quad band GSM-GPRS module attached with serial port of the controller. It can
also be use for automated toll-tax payment.
• This method of violator detection will be a full-proof method of curbing traffic
violation in India and is also implementable with the future plans of GoI of
implementing tags in cars and motorcycles.

9. ADVANTAGES
• More efficient
• Less waiting time
• Efficient operation during emergency mode
• User-friendliness
• Reduces vehicle theft chances
• Reduces driver frustration and road rage
• Scope for further expansion
10. CONCLUSION
• The “Intelligent Traffic Light Control Using Embedded
System” is more reliable, highly accurate and offers
higher performance over the traffic light controllers that
were used earlier.
• The easy availability of good design tools and software
engineers has been two key factors in fuelling the
growth of embedded systems.
• The Intelligent traffic control is just a small part, looking
at the bigger picture it has large-scale application in
ITS(Intelligent Transportation System).
