Abstract -
The aim of our project is to develop a
Density Based Traffic Signal System using PIC
microcontroller. Nowadays, controlling the traffic
becomes more difficult because of rapid increase in
the number of automobiles and due to large time
delays between traffic signals. In order to reduce
this problem, we can choose density based traffic
signal system. In this system, we will use IR sensors
to measure the traffic density. We have to mount
three IR sensors for each road; the distance between
these sensors will depend on nature of traffic on a
particular junction. These sensors will sense the
traffic on that particular road. All these sensors are
interfaced to the PIC microcontroller. Based on
these sensors, controller detects the traffic and
dynamically set up the time delay of signals.
