Sistem Pengaturan Lampu Lalu Lintas dengan Pendeteksi Kemacetan
Abstract: This research was
based on a highly frequency of traffic jam on the traffic flow. Traffic controlling
was usually used a fixed time traffic signal system. Fixed time traffic signal
is traffic light which in operation is
used constant time. This system had weakness because this system could not
adapt automatically with situation. According
that reason, the aim of this research was to design and to create a
system, which can detect number of vehicle to decrease traffic jam. The device
was used several
components such as microcontroller ATMega128
as controller device, distance sensors GP2Y0A21 as detector object. LED was used to show a sign to stop, go
forward, and be careful, then seven segment was used to show time for LED.
Power supply circuit is as voltage source to all circuits in this system. GP2Y0A21 sensors will detect vehicle which
pass in each branch of the road. Sensors will detect vehicle density with four
conditions. That condition consist of normal, jam level 1, jam level 2, and
total jam. Normal time for green light to turn on was 5 second in each
intersection. The more vehicle detected by sensor, the green light will turn in
longer time. The results of the experiment from traffic light is to control
system with distance sensors GP2Y0A21 as jam detector showed by LED, and seven
segment will turn on according to sensors input. To sum up, the design of
traffic light in this research could adapt time, particularly in how long the
green light to turn ON for each traffic jam.
