Design and Build a Portable Traffic Light Based on Wireless Communication

Abstract

Highways are an important means of transportation for people to achieve their desired goals, therefore the community and the general public also need highways that are in prime condition. However, as time progresses, many highways are not maintained, so many community activities are disrupted, resulting in queues or traffic jams. Traffic jam itself is a condition where traffic is blocked due to several factors, examples of these factors are road damage, facilities that do not function as they should, such as traffic lights that go out and require officers to come to regulate traffic flow. Therefore, we need a system that is easy to carry, easy to install and easy to apply. This research entitled "Design of a PorTable Traffic Light Based on Wireless Communication" is expected to work well with a system that can calculate queues using ultrasonic sensors and a traffic light system that can make decisions about whether the traffic light will work. The results of this research are divided into 2 which can work continuously and automatically. The results of testing the sensor system can work to calculate distances up to a range of 823 cm, but this exceeds the normal size in one lane in Indonesia which is only 600 cm wide. The percentage of error on the sensor is no more than 1% and testing the timer on the traffic light works quite well with a percentage of green light error of 4.67%, yellow light 55.5% and red light 4%.
