TY - JOUR ID - TI - CLINICAL DATA WAREHOUSE A REVIEW AU - Alaa Alaa Khalaf Hamoud, Ali Salah Hashim, Wid Akeel Awadh PY - 2018 VL - 44 IS - 2 SP - 16 EP - 26 JO - Iraqi Journal for Computers and Informatics المجلة العراقية للحاسبات والمعلوماتية SN - 2313190X 25204912 AB - The increasing in the number of vehicles on streetshas led to traffic congestion. In order to reduce the waiting timein cases of emergency, the idea of this work is suggested. Thiswork is divided into two parts, the particular part and softwarepart. The first circular particular part is a model which consistsof four lanes junction of a traffic light, it also has GSM system (Global System for Mobile Communications). The GSM andlamps of the traffic light are connected to Arduino UNO. TheArduino controls every signal which is coming from the inputs(GSM) to software and display to the outputs (lamps) Thesecond circular particular part is a model which consist samecomponents the first circuit except replace the GSM withIR(infrared Remote).The goal from this work is to help us in theemergence cases, the opening and closing of the traffic light arecontrolled by using GSM system and IR, the time of each lane,is controlled that means reduce the crowding.
