Multiple traffic control using wireless sensors anddensity measuring camera


2/19

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.

Gatsometer Speed equipment and traffic light camera.

.

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.

ADVANTAGES

Higher image resolution

Transport safety

Flexibility

Distributed intelligence

POE - Power over Ethernet


14/19

DISADVANTAGES

Higher initial cost per camera

Lack of standards

High network bandwidth requirements

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
