Present system is completely static case.

vehicles must wait at the intersection for a predefined time

until microcontroller switches green light for that lane.

Exists no process of preemption.

No green light service for priority based vehicles.

Adaptive system

provides immediate pass through for prioritized vehicles

like:

Ambulance

Fire engine

Police services

VIP vehicles

dDeployment of wireless acoustic sensors on either side of the lane.

Sensor placing distance can be from 10-11 meters.

Wireless acoustic sound sensors:

Road rule standard: Emergency vehicles – Honk intensity:128dB

Transportation vehicles-Honk intensity:86dB

Acoustic sensing is possible by setting threshold detection value.

Thus differentiation is made between Transport & Emergency

vehicles

Arranged up to 300 to 400 meters from the intersection.

Sensor Detection & communication with neighbors:

Each road side sensor will

communicate with

controller.

Ever intersection will

communicate with next

intersection

Entire communication is carried out wirelessly using

ISM band.

Dead lock scenario:

solution :

System working:

Deadlock scenario-2

challenging and wishing to be a future scope of

using solution through image processing:

Conclusion:

Proposed system is fully automated and can be implemented

for present existing system.

For a developing country like India with heavy traffic this type

of effective adaptive system is a urgent need.

Using Acoustic WSN’s for implementation is very easy and

also inexpensive and high efficient operation during

emergency mode.
