Abstract :
The number of vehicles in Indonesia continues to increase every year. Based on
data from the National Police Headquarters the number of motorcycles circulating
in Indonesia in the past five years increased from 17,002,130 units to 76,381,183
units. Therefore traffic lights play a very important role in transportation. With the
traffic lights, it can help police officers more easily do the work in dealing with
congestion. It will be different if there is no traffic light. In that case, the motor
rider, the community and the police will stuck in traffic jams during their daily
activities on the trip. For this reason, it is necessary to apply the traffic lights to
prevent traffic jams. The design of this traffic light control system uses Arduino Uno
as the controlling brain of all connected components and to process the data.The
data that has been scanned from sensors, infrared sensors and photodiode is used
to detect the presence of vehicles. In the photodiode sensor testing, it can only detect
vehicles with a maximum distance of 80 cm. We use 2 pieces of XBee S2 pro as
Coordinator and Router. XBee as a Router is used as a mean of communication
between XBee from Arduino through Radio Frequency media. XBee as a
coordinator is used to display on a PC created using Visual Basic 6.0. XBee testing
can only communicate between XBee at a maximum distance of 5 meters more than
that, it will experience Zigbee LOSS Error. Visual Basic software is used to display
and monitor the use of tools at traffic lights. The LED is used as a traffic light
indicator and a time indicator of the lights and a 16x2 LCD to display the time
duration and number of vehicles. From the overall test, this Final Project has
worked as expected. It can be used that operated based on the default settings that
has been specified and can monitor the working system of the device.
