MODEL PENANGGULANGAN KEMACETAN LALU LINTAS PADA TRAFFIC LIGHT SIMPANG TIGA MENGGUNAKAN LDR SEBAGAI INDIKASI KEPADATAN KENDARAAN

Abstract

Have been made a traffic light model using LDR as a sensor to detected the jamming. This model used to reduce the traffic jam and hoped can reduce the traffic accident. This model consist of 9 LED as the simulator of the traffic light, port parallel wire as a connector between computer and the circuit a compute with Delphi 7.0 as the controller for the lamp in the traffic light. This gadget work if the two LDR sensor in one of the read is covered, then the sensor will send the signal to the traffic light, and make the green light as much larger then light in the other read that didn’t covered or didn’t happened the jam. Both of the joint street which unstuck, red light suitable with green light on the joint street which happened jamming.
