Pengembangan Prototipe Lampu Lalu Lintas Pejalan Kaki Berbasis Mikrokontroler MCS-51 yang Diinisiasi dengan Tombol

Abstract

Nowadays, in Indonesia, pedestrian’s right to cross through zebra cross is often abandoned. On the other hand, Law No. 22 of 2009 concerning Traffic and Road Transportation, article 130 paragraph 2 explicitly mentioned that pedestrian who cross through zebra cross shall be prioritized. This study develops two button-initiated pedestrian traffic light prototypes using MCS-51 microcontroler, to be implemented in zebra cross. The first prototype utilizes several push-buttons, whereas the second prototype uses keypad as the button to initiate the traffic light. Pressure on the button will trigger the crossing condition, where the vehicle’s traffic light becomes red and the pedestrian’s traffic light becomes green. In this condition, seven segment will show the count down time that can be selected through the button. This study shows that the push-button prototype is more user friendly and easily maintained. Meanwhile, the keypad prototype is more flexible in terms of selecting the crossing time.
