The main goal of engineering is the planning and
management of traffic systems.
One aspect of the project aims at developing a traffic
control algorithm for future technology.
We then deal with all four routes
i.e. East, West, North and South
4.
A newly emerged area is demand estimation
through microscopic traffic modeling.
According to development of our project it is
a step by step analysis of traffic system.
Emergency sensor is built upon, to
continuously check the emergency situations
like ambulance, police and fire-bridge etc.

1. It calculates number of vehicles
2. It compares no. of vehicles on both side and
alert the machine
Emergency eV_sensor
1. It has 2 radio receivers
2. When desired frequency received it will send
the desired signal to the control state chart/

Traffic is the most essential part of modern
world as “Time is money”.
The Quality Assurance Professional can be a
part of each of these review process.
It is basically based on four way traffic
But with slight modifications it can be made
for any way systems effectively as it is based
on Boolean algebra
