Abstract:
Traffic congestion problem is a phenomenon which contributed huge impact to
the transportation system in country. This causes many problems especially
when there are emergency cases at traffic light intersections which are always
busy with many vehicles. A traffic light controller system is designed in order
to solve these problems. This system was designed to be operated when it
received signal from emergency vehicles based on IFTTT application that
been install in user phone and used the Programmable Integrated Circuit (PIC)
Nodemcu Esp 32 microcontroller to change the sequence back to the
interruption mode. This system will reduce accidents which often happen at
the traffic light intersections because of another vehicle had to huddle for given
a special route to emergency vehicle. As the result, this project successful
analyzing and implementing the IoT communication; IFTTT application
communicate with Arduino control system integrated with LabView for
monitoring. The prototype of this project is using the Nodemcu Esp 32 for
interruption the sequence mode of traffic light when emergency vehicles
changing the sequence back to the normal sequence before the emergency
mode was triggered. In future, this prototype system can be improved by
controlling the real traffic situation, in fact improving present traffic light system
technology.
