Objectives

Design a synchronized traffic light control system that minimizes traffic congestion in the adjacent blocks.

Introduction

It is well known among GSU students and staff that the T$-$deck on Auburn Ave. causes severe traffic congestion during the morning rush hours. While it may not be easy to speed up the gate intake of the T$-$deck itself, an optimized traffic control mechanism will alleviate the traffic congestion nearby to a certain degree. In this lab, each group is tasked with proposing a traffic light control strategy that minimizes traffic congestion in the adjacent blocks and then

Given:

Auburn Ave is a two$-$way street. Peachtree Center Ave and Courtland Ave are one$-$way streets.

Incoming traffic flow speed is marked near each arrow that indicates the traffic flow directi$$ The pink arrow indicates traffic to the T$-$deck, and the blue arrow indicates bypassing

traffic.

$$ Each car will take at least $20$ft of space to ensure safety.

$$ If cars are queueing at the traffic lights, it will take each car $2$ seconds to pass the

intersection if there is space for the car on the street segment the vehicle is going to$.$

$$ If the queue at the intersection exceeds the length of the road segment, the cars will

back up at the street segment of the incoming traffic. $($For example, if Auburn Ave

between Courtland St and Peachtree Center Ave is full of vehicles going from east to

west, they will start backing up at the right turning lane of Courtland St$.)$

Design Requirements:

$$ No collision

$$ Two$-$way streets require a separate left$-$turning period. $($No left and straight

concurrently$)$

$$ Cars from any incoming directions should not wait at the traffic light for more than $2$

minutes.

Tasks

$1.$ Create a finite state machine diagram

$2.$ Convert the FSM to state transition table

$3.$ Simplify the state transition table using Karnaugh maps

$4.$ Implement the state machine using logic circuitson.
