STAR Light System

What is STAR Light An acronym for Smart Traffic Light It focuses on time manipulation This means it sets time based on the number of cars behind a traffic cars The lesser the cars (until it reaches minimum) the shorter the time This system is regulated by light sensors

The problems with normal traffic light b. c. d.

It has a fixed time setting. Therefore: it causes delays The time interval is impractical Traffic will become inefficient HYPOTHESIS Delays behind traffic light could be reduced if the timer in a traffic light could be manipulated proportional to the amount of vehicles behind the traffic light.

Objectives To increase knowledge in the field of physics especially areas involving time manipulation in a traffic light To develop a system which comply to our means and objectives to manipulate time in a traffic light proportional to the amount of vehicles behind the traffic light To enhance knowledge in fields involving risk assessment and probabilities as well as challenges the mind to come up with creative solutions

Methodology Carry out a survey to obtain feedback from pedestrians as well as drivers Comparing and contrasting the current traffic system with our STAR Light system Gather information and data needed by referring pages from the internet, reference books, magazines and visit to the library. We discussed it’s outcome with various experienced teachers in fields of physics and mathematic teachers to cover all possible outcomes and probabilities Have discussions and assessment with fellow participants as well as with our advisor

Benefits to develop an effective system to manipulate time proportional to the amount of cars Minimize the time behind the traffic light To avoid delays behind the traffic lights and decrease the amount of traffic jams To enhance the technology regarding traffic light to an advance level

Enhancement Proposal:  a circuit which based on logic gates such as the usage of IC 5703 (AND gate), IC 5786 (X-OR gate) and IC 4017 (decade counter)  To increase accuracy and efficiency in terms of time
