LCD

LCD (liquid crystal display) is the technology used for displays in notebook and other smaller computers. Like light-emitting diode (LED) and gas-plasma technologies, LCDs allow displays to be much thinner than cathode ray tube (CRT) technology.They use the same basic technology, except that arbitrary images are made up of a large number of small pixels, while other displays have larger elements. LCDs can either be normally on (positive) or off (negative), depending on the polarizer arrangement. For example, a character positive LCD with a backlight will have black lettering on a background that is the color of the backlight, and a character negative LCD will have a black background with the letters being of the same color as the backlight. Optical filters are added to white on blue LCDs to give them their characteristic appearance.

LINEAR ACTUATOR

 A linear actuator is an actuator that creates motion in a straight line, in contrast to the circular motion of a conventional electric motor. Linear actuators are used in machine tools and industrial machinery, in computer peripherals such as disk drives and printers, in valves and dampers, and in many other places where linear motion is required.Hydraulic or pneumatic cylinders inherently produce linear motion. Many other mechanisms are used to generate linear motion from a rotating motor.

To reduce the hold up, we end to propose our plan of dominant the road divider for an additional lane as per would  like with the assistance of IOT.
1. As per the holdup ascertained in our lifestyle through the time period cameras.

2. We gather the info collected from the cameras and send them to cloud for analysing the traffic.

3.In analysis half, the info are going  to  be analysed mistreatment raspberry  pi through image process.

4. After analysing, the required action is performed whether or not to  push/pop the divider.

5. To build the higher than aforesaid proposal we tend to need ton of funds and time.

6. So, for nonce we tend to square measure coming up with our paradigm in Movable Mechanism (left/right) rather than push/pop mistreatment Arduino. The main advantage in the system is No human power is required.

code for push and pop of the line divider .

WORKING OF ULTRASONIC SENSOR

Ultrasonic sensors work by emitting sound waves at a frequency too high for humans to hear. They then wait for the sound to be reflected back, calculating distance based on the time required. This is similar to how radar measures the time it takes a radio wave to return after hitting an object.

While some sensors use a separate sound emitter and receiver, it’s also possible to combine these into one package device, having an ultrasonic element alternate between emitting and receiving signals. This type of sensor can be manufactured in a smaller package than with separate elements, which is convenient for applications where size is at a premium.

While radar and ultrasonic sensors can be used for some of the same purposes, sound-based sensors are readily available—they can be had for just a couple dollars in some cases—and in certain situations, they may detect objects more effectively than radar.

ARDUNIO CODE

const int pingPin = 7; // Trigger Pin of Ultrasonic Sensor

const int echoPin = 6; // Echo Pin of Ultrasonic Sensor

void setup() {

   Serial.begin(9600); // Starting Serial Terminal

}

void loop() {

   long duration, inches, cm;

   pinMode(pingPin, OUTPUT);

   digitalWrite(pingPin, LOW);

   delayMicroseconds(2);

   digitalWrite(pingPin, HIGH);

   delayMicroseconds(10);

   digitalWrite(pingPin, LOW);

   pinMode(echoPin, INPUT);

   duration = pulseIn(echoPin, HIGH);

   inches = microsecondsToInches(duration);

   cm = microsecondsToCentimeters(duration);

   Serial.print(inches);

   Serial.print("in, ");

   Serial.print(cm);

   Serial.print("cm");

   Serial.println();

   delay(100);

}

long microsecondsToInches(long microseconds) {

   return microseconds / 74 / 2;

}

long microsecondsToCentimeters(long microseconds) {

   return microseconds / 29 / 2;

week 4 day 2

The background of this project is to reduce traffic  by smartly sensing the traffic flow on either sides of the  divider and  move the divider accordingly ,hence saving time and fuel and also providers safety measures

LITERATURE SURVEY

•  K.Vidhya, A.Bazila Banu,[1]  Has proposed  Traffic Signal system is based on density on the amount of vehicles travelling on daily basis . by going through the above mentioned paper we understand present traffic signal system                                   
•   Priyanka Khanke, Prof. P. S. Kulkarni , [2]  Has proposed A  Technique on road trance analysis using  image processing .this paper tells us a about the image processing  and implementation of it to analyze traffic

PROBLEM STATEMENT
 

•  In present scenario we have fixed road dividers which allows only limited number of vechicles in ongoing and incoming traffic , in order to have a flexible road space  depending vehicle density on road . hence to overcome this we design  a movable road divider .
