However, the increasing population  has led to several inconsistencies of traffic  lights.  This work presents the design and construction of  an improved digital lighting system for the  Government Reserved Area (G.R.A.) junction, Aba ¿  Port Harcourt expressway, Nigeria based on a  principle of generating electrical pulses that are  counted and decoded with Johnson counters. The  CD4017 counter and decoder forms the heart of the  circuitry which is driven by pulses from a signal  generator (NE555).Based on the traffic flow data  collected from the junction, timing was allocated to  each of the roads to show improvisation. This timing  was assigned to pulses from the synchronous  counters. Radiant light and heat from the sun is  harnessed and used to charge a 6v battery using  photovoltaic cells. This powers the circuitry in the  event of power failure.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783844312393\"\u003e\u003ch3\u003eAN IMPROVED TRAFFIC LIGHTING SYSTEM FOR THE GRA JUNCTION, ABA -PORTHARCOURT EXPRESSWAY, NIGERIA USING DUAL POWER SUPPLY\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783844312393","offer_id":39470065156189,"sku":"9783844312393","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/f14fc54b-8259-40c2-8b14-9b04e5ac6690.jpg?v=1774761413","url":"https:\/\/shop.autorenwelt.de\/products\/an-improved-traffic-lighting-system-von-kelvin-ukoima","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
