The things that should be known in the manufacture of traffic lights



1 . This software can be run on all Operating systems , such as Linux , Macintosh , and Windows , including Windows XP , 7.82 . Creating designs traffic lights , with3 . Specifying Color Display ,• Red• Yellow• Green4 . Using Microkontroler as the chip , its components are transistors BC107 ( to switch the counter ) and a resistor ( For Retaining Flow )5 . Then programmed using a computer , with the stipulation red Stop signs , street signs and Colour Green and Yellow Color by booth sign ,6 . Camera ,
 
Mmenggunakan camera as observer vehicle at an intersection density . The camera will take a picture of the intersection of the above when there is a vehicle which then becomes the input to the image processing for images when compared with state of the empty intersection . The captured image is the pixel format , so that comparison is the difference of each pixel . From the comparison of the data obtained would the pixel density percentage in each lane . Percentage of the data density of each lane will be processed by a fuzzy logic controller to decide how long the green light will be lit .7 . Infrared Sensor
 
On the side of the road can mengetahuai maximum distance that the number of vehicles in the intersection , with a radius of 15 meters , infrared sensor , which works on sensors or infrared rays emitted ultrasonic waves and then captured again by the sensor , which is then processed by the system ,8 . The system is placed in an enclosed place , which is fused in light boxcasing traffic light , the system is designed is able to overcome the obstacles faced by the weather such as dust , heat and rain. This system should also be sturdy and able to withstand shocks or vibrations that arise as a result of the movement of surrounding vehicles9 . Assumed to be 1.7 m width of the car - 2 m , with a distance of cars stopped along the boundary line of 1.5 m , then the car can expect to turn to the left or straight without worrying about hitting the car body box traffic light
