INTRODUCTION The aim of the project is to solve traffic congestion which is a severe problem in many modern cities all over the world To solve the problem, we have designed a framework for a dynamic and automatic traffic light control system
3
Hyperspectral ImagingStatic VS Dynamic Traffic controlStatic: In static control generally, each traffic light on an intersection is assigned a constant green signal time.
Dynamic: In dynamic control the green signal time of the traffic lights is assigned based on the present conditions of traffic.

When will the stupid light become green again

MCU 8051 IDEMCU 8051 IDE offersA transparent view on simulated program for 8051.Easy source code editing even for an user with small knowledge of the assembly language.User friendly, easy to use, and yet sophisticated enough IDE for 8051.Support for more than 70 microcontrollers based on the famous 8051 design.Limited support for HW tools, the IDE has some hardware tools on its own and other can be more or less used from within the IDE.

18AdvantagesDensity based traffic light control have many advantages compared to time based traffic controlThe work which is done by traffic inspector will be perfectly done by the microcontroller in the circuit with the help of sensors and the program which is coded to the microcontroller.We can save considerable amount of timewe can avoid unnecessary occurrence of traffic jams which causes public inconvenience.
ConclusionThus from this theory we can conclude that using the method of density based control of traffic lights we can save a considerable amount of time and also we can prevent excessive traffic jams thus leading to smooth traffic flow.
