This document describes an Adaptive and Autonomous Traffic Management System (AATMS) created using LabVIEW. The system uses a camera interfaced with a microcontroller to calculate vehicle density in each lane, detect license plates, and control traffic lights autonomously based on vehicle numbers. It detects vehicles in each lane using background subtraction, thresholding, and particle analysis. License plates are localized using color planes and morphology, then segmented and recognized using OCR. Traffic lights duration is determined algorithmically based on vehicle counts. The system aims to reduce traffic and waiting times. Future applications include real-time traffic updates, automatic tolling, and detecting traffic violators.

2. INTRODUCTION
The Adaptive and Autonomous
Traffic Management System
(AATMS) is an Intelligent Transport
System(ITS) and is of considerable
interest because of its potential in
managing real-time multi- lane traffic
using a camera interfaced with a
microcontroller.

7. TRAFFIC LIGHTS CONTROL
ALGORITHM
The duration of active green signal depends upon the number
of vehicles/vehicle density in each lane.
The loop starts with Lane 1 and iterates till Lane 4 taking one
frame of video at a time.
If Ambulance is detected, an interrupt is generated to give
active green signal to that lane after which the loop iterates
sequentially like before.
An over-ride switch is provided. When this is active, an equal
delay is provided to each lane independent of the number of
vehicles. This is useful if cameras are to be uninstalled for
maintainance work.
The data of number of cars of each lane is stored in a 1-D
array for processing.

8. ASSUMPTIONS…
At a time, only one
lane has an active
green signal
Left turn is always free
The duration of
forward green signal
and right turn green
signal is same.

10. APPLICATIONS
PREVENTION OFHEAVY
TRAFFIC JAMS
The system sets different delays for
different lanes depending upon the
number of vehicles in that lane, thus
preventing unnecessary traffic jams.
REAL TIME TRAFFIC
UPDATE
The real time traffic
information of traffic density
can be updated on the traffic
website wherein the users can
easily access that information.
SOLUTION TO
UNNECESSARY WAITING
Our system provides the
method which successfully
reduces the waiting time of
commuters at traffic junctions
even if there is no traffic.

15. APPLICATIONS
GENERATION OF DATABASE
This system automatically generates
the database of identified license
plates from which the defaulters can
be identified.
AUTOMATED PARKING SYSTEM
In Multilevel Parking Systems,
different spots can be pre-assigned
to different users. So the users is
identified via Registration Plate
detection and their vehicles are
parked automatically.
AUTOMATED TOLL
COLLECTION
The commuters can be
identified via license plate
detection and automatically
the toll can be debited from
their account.
AUTOMATIC
GENERATION OF E-
CHALLAN
The commuters can be
identified via license plate
detection and automatically
the challan can be debited
from their account.
