Causes of Traffic Jam
 Increasing number of Vehicles.
 Trucks and CommercialVehicles
 Non-Recurring Highway Incidents:
 Crash
 RoadWorks.

Effects of Traffic Jam
 Fuel Consumption
 Air Pollution
 Parking Problems
 Accidents
 Emergency Services
 Mentally Retarded.

SO WHAT DO WE REALLY NEED???
IS IT AN ALTERNATIVE
ROUTE???
OR
SOME INFO ON HOW LONG WILL
THE CONGESTION LASTS???

IMAGE PROCESSING

IMAGE PROCESSING
An image is taken by a
DIGITAL CAMERA
Image is sent to ComputerImage is a 3 dimension
matrix of number describing
the intensity values of RGB
components
Algorithm is applied to
change the values
appropriately to bring out
desired effects

8051 MICROCONTROLLER
The 8051 microcontroller consists of:
• 4 Kb of ROM .
• 128bytes of RAM (including SFRs) .
• 4 ports having in total of 32 input/output lines.
• 2 in-built timers.
• A buffer register to hold the data during serial communication(SBUF).

IMAGE PROCESSING
Image RGB to GRAYSCALE conversion
GRAYSCALE to BINARY conversion based on a
Thresholding value
Selecting the REGION of INTEREST
Edge Detection using SOBEL’S EDGE DETECTION
Filtering using AVERAGE FILTER method
Generating a TIMER value

Snapshots can also be taken during the green signal to
analyze if there is a sudden increment in traffic
FUTUREENHANCEMENTS
Traffic density can be sent to other traffic crossings to ease
the traffic movement during peak hours.
These data can be made available on GSM based query
services to give the traffic movement data to private car
users to plan their movement accordingly.

CONCLUSION
 Low cost and ease in installation.
 More accurate than traditional systems.
 Reduction in manpower.
 Easy to detect road accidents.
