Generic intersection design
Static intersection case:
Present system is completely a static casevehicles 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.
ITS system: Adaptive system provides immediate pass through for prioritized vehicles like: Ambulance Fire engine Police services VIP vehicles
ITS system Design:
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.
