INTRODUCTION Traffic research has the goal to optimize
traffic flow of people and goods.
Traffic light optimization is a complexproblem. Even for single junctions there
might be no obvious optimal solution.
.We propose two approaches. In the firstapproach - to take data/input/image fromobject/subject/vehicle.
In the second approach - to process theinput data by Computer andMicrocontroller and finally display it on thetraffic light signal to control the ClosedLoop System and also optimized visualmonitoring of traffic using Camera.

Wireless sensor network
A wireless sensor network (WSN) is a
wireless network consisting of spatially
distributed autonomous devices using sensors tocooperatively monitor physical or environmental
conditions, such as temperature, sound, vibration,
pressure, motion or pollutants, at different
locations.
The development of wireless sensor
networks was originally motivated by military
applications such as battlefield surveillance.
However, wireless sensor networks are now
used in many civilian application areas, including
environment and habitat monitoring, healthcare
applications, home automation, and traffic control.

Road IntersectionConfiguration
INTERSECTION CONTROL
AGENTThe system prototype consists of
four elements
1) The wireless sensor
network (WSN)
2) The intersection control agents (ICAs)
3) The actuators (i.e., traffic lights)
4) The environment

Types of control agents Adaptive traffic light control
Message types
-sensor nodes to ICA-ICA to sensor nodes
-greedy ICA to ICA
-ICA to ICA with coordination

All Traffic camera systems are digital and provideProsecutable images in all weather conditions, 24 hours a day.
The 11 Mega pixel camera will cover 4 lanes plus a hard
shoulder showing context (scene) information and clearly
readable license plates.
The minimum rate of image capture for a typical
installation, taking into consideration the flash
recharge rate, is approximately 300 milliseconds.

Gatsometers innovative photo
enforcement systems
and services make a valuable
Contribution to traffic safety
.Our modular approach to design
ensures that systems are
configured to meet the most
demanding traffic enforcement
requirements.

Gatsometer's Digital Radar Camera System (DRCS)
Enforcement Systems
Speed enforcement - Gatsometer pioneered the use
of speed enforcement and now supplies a
comprehensive range of equipment for monitoring
and processing speed offences.
Red light enforcement - Automated control is vital
for safety at intersections; whether it is a two-lane
street or a multi-lane intersection, Gatsometer has a
robust, reliable and innovative solution.

Speed Enforcement Cameras
Multi Camera System (MCS): may be used at signaledintersections for red light Enforcement
,
Digital Radar Camera System (DRCS) :captures high quality images in Diverse environmental
and lighting conditions and may be used in both mobileand fixed Configurations. Gatsometers range ofdetection technologies provides a solution for alllocations and enforcement applications

INTELLIGENTTRANSPORTATION APPLICATIONS:
Emergency vehicle notification systems:
Automatic road enforcement
The minimum set of data contains informationabout the incident, including time, preciselocation, the direction the vehicle was traveling,and vehicle identification
A traffic enforcement camera system, consistingof a camera and avehicle-monitoring device, is
used to detect and identify vehicles disobeying aspeed limit or some other road legal requirementand automatically ticket offenders based on thelicense plate number.

Variable speed limits
Automatic number plate recognition
Recently some jurisdictions have begunexperimenting with variable speed limitswhich change with road congestion andother factors
Automatic number plate recognition(ANPR) is a mass surveillance method thatuses optical character recognition on imagesto read the license plates on vehicles.

CONCLUSION
In this paper we propose approaches to controller themultiple traffic light in a City by applying a simple
method using wireless communication network and
GatsometerSpeed Equipment and Traffic Light Cameras
for display and monitoring City traffic.
In this paper we also approaches the another aspect of
traffic control is controlling traffic light in a way that
minimize the time drivers have to wait.

Future aspects of this works is communicating the
situation of traffic to the individual of City using LCD
display on every traffic unit and vehicle also by
transmitting audio message using and wireless
transmitting
