Introduction

Project information

Software used

Conclusion

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

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.

Density sensor

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/

On -

it represents the traffic

control system is

working under

software control and

without any abnormal

condition

timing - this state

took the responsibility

of reducing the time

by one second

Manual_mode- it

represents the traffic

control system is

oprated manually due

to external

interferance

Emerg_ns - there is

an emergency

condition in north

south route

Emerg_ew - there is

an emergency

condition in east west

route

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
