Abstract
One of the vital inventions of mankind is the traffic lights which up to the present are continuously still being modified for a more satisfactory result. Traffic lights are used to control competing flows of traffic and serve as road signals to cars for a smooth and convenient travel. With the aid of the obtained knowledge in logic circuits and digital electronics, a one-way traffic light design was established.
The design was initiated by a definite goal which is to make a one-way traffic light mounted to the road intersection with sensors used to detect the presence of vehicles leading to light transitions. After which is the execution of logical operations of the design with the used of Moore model showing how and when the network changes state. The now well established design was then tested on a MULTISIM where the obtained result was analyzed. Modifications were done until the desired output, conforming to the design specifications were attained. Armed with sufficient and efficient technical know-how, the Simple Traffic Light Design was accomplished.
Introduction
During the horse and buggy days, traffic in big cities was often heavy. With the coming of automobiles, the situation got even worse. Precisely, traffic on roads take place when a number of pedestrians, ridden or herded animals, vehicles, streetcars and other conveyances occurs either singly or simultaneously while using the public way for purposes of travel.
Traffics are hindrance to those who are in a hurry and may also cause accidents. To avoid such occurrence, traffic lights are adapted for street use. These are signaling devices positioned at road intersections and other locations to control competing flows of traffic. They alternate the right-of-way of road users by displaying lights of a standard color. They make use of three colors, each provides distinct signal that a car must follow. There’s a green light allowing a car to proceed in the direction denoted, a yellow light denoting prepare to stop short of the intersection, and a red light prohibiting it to proceed.
Time-controlled and sensor-controlled traffic lights have been implemented nowadays on different types of road intersections such as cross intersections, T intersections and Y intersections. The former operates on a timing mechanism that changes the lights after a given interval while the latter senses the presence and absence of vehicles, and reacts accordingly. Sensor-controlled system reacts to motion to trigger light changes. Putting it into operation in a one-way road intersection, sensors are positioned on each lane at the cross-section to detect that a volume of cars has pulled up. These detectors are driven by switches that cause light transitions.
To govern the actions of the traffic system, algorithms will be used. Specifically, Boolean logic will be employed. It consists of binary variables and a set of logical operations. The said variables will be used to represent state transitions. The logical operations will be executed using a Moore model. Herewith, is a sequential circuit that will be composed of a state register driven by an input combinational logic. It will also consist of an output combinational logic which is a function of state registers.
Aided with the right concepts and principles with the well-defined design parameters, the researchers eagerly hope to come up with the desired output which on this particular case is the own proposed one-way traffic light design.
