ABSTRACT

Abstract

Traffic control system has been in use over the years, from manual to digital and automated digital which is the current era ushered in by this research. Lots of challenges which includes poor timing, collision due to inconsistent signaling and many more has led to the late arrival of commuters or personnel to their various offices and indeed has cause a poor economic yield. In order to overcome this problem, a design and construction of density-based traffic signal with a delay of 1000ms to control the traffic based on density at the four way cross road using Arduino Uno Atmega 328P has been implemented. The result has shown that the traffic congestion will be completely reduced if not eliminated by the adoption of this design and programing which controls the censored light signals. The sensors which are present on sides of the road detects the presence of the vehicles and sends the information to the microcontroller where it decides how long a flank will be open or when to change over the signal light.
