ABSTRACT
This project work is on design and construction of a 2-way traffic lighting system. A 2-way Traffic light is signaling device positioned at 2-way road intersections, pedestrian crossings and other locations to control competing flows of traffic.
The road construction safety traffic light system is designed to replace a manual traffic control on a road construction sites. This device can replace one or both flaggers during the two lane closures on the event of a road construction. The road construction safety traffic light system is considered one of the best devices in work zone traffic flow control systems. The device is a portable traffic light unit which can be best utilized in controlling traffic flow in a road construction site for long term or short term lane closures and to control two-way traffic in a single lane. By implementing new technologies in automating traffic flow in road construction site could possibly eliminate the usage of a conventional flagman at all times. The road construction safety traffic light system is a practical solution to solve problems which contribute towards hazards at road construction site and to be inline with the road safety regulation which is taken into granted by the contractors. The automated portable traffic light system can reduce direct costs in man power utilization and increase safety for the road users and construction workers by eliminating the need for a human flagmen. This system is applicable for public and privately funded road construction projects that require overnight or 24-hour traffic control as well as in different weather conditions.
The purpose of this project work is to design and construction a 2-way traffic light device that can be used to control the flow of traffic at 2-way road intersection.

INTRODUCTION
1.1 GENERAL DESCRIPTION OF THE PROJECT
The trend in electronics is tending into digital electronics which make it possible for the birth of computers, digital communication systems like GSM, and industrial automation.
This is the main reason why we have chosen a project topic on the design and construction of an automatic 2-way traffic light control.
This system has always been right from the advent of digital electronics in Nigeria.
Our own project design is the miniature type that employs six (6) light emitting diodes (LED) as the visual display unit (VDU).
The entire system contains six (6) different plus the block that contains the light omitting diodes which makes it five (5) blocks altogether and also a power supply unit (PSU) that supplies the battery voltage.
At the input is an astable multivibrator (AMV) built using 555 timer that provides the intelligence clock signal that determines the timing based on what the time sequence generator interprets from the clock (10 ten decade counter). Then the binary corded decimal (BCD) output is now ored using discret junction diodes as OR gate such that an output is adapted using the functional behaviour of OR-gate into an inter-fase card that contains arrays of transistor switching circuit that switches the six (6) LEDS based on the timing sequencing such that three (3) LEDs for one lane, the other (3) goes for the other lane, which gives vehicles passing from one lane to another lane traffic signal so as to avoid accidents.
1.2 DESIGN OBJECTIVE
The objective of this design is to create an electronic circuit using digital components and a few linear components such that a digital output is raised to control the traffic at 2-way junction using six (6) lamps rather light emitting diodes LEDS, where three (3) lamps or LEDs serves for one lane and t he other three (3) serves for the other lane, among the three (3) LEDs one is Red, which signifies that vehicles should move.
The second is green and it signifies that vehicles should stop.
The third as amber which signifies vehicles should get ready to move.
1.3 SIGNIFICANCE OF THE PROJECT
The project design work signifies a lot in modern industrial electronics.
This design that replaced the manually used agent which is the traffic warden positioned at different traffic junctions.
In most developed towns in Nigeria, this system is employed at every 2-way junction, so that traffic jam or hold up will be highly controlled and also accidents at this junction are highly minimized.
In advance countries, the type of traffic light employed are inform of robot whose eyes serves as the visual display unit (VDU) when the traffic rule is violated the error detector is effected by the mechanical action of the robot.
1.4 PURPOSE OF THE PROJECT
The purpose of this project work is to design and construction a 2-way traffic light device that can be used to control the flow of traffic at 2-way road intersection.
