Turn Off Signal Alert System

Abstract

Road crashes remain a significant global concern, resulting in over 1.35 million fatalities and up to 50 million injuries each year. Research indicates that the causes of these accidents are multifactorial, with human error responsible for more than two-thirds of incidents—particularly in developing countries. A common yet often overlooked contributor is the failure of motorists to deactivate their turn signals after completing a maneuver. This oversight can mislead other road users, potentially causing confusion and increasing the risk of collisions. To address this issue, a Turn Signal Alert System has been developed. The objective of this project is to design a system that uses vibration feedback to notify motorcyclists when their turn signals remain active after a turn, thereby promoting timely signal deactivation and reducing accidents related to signal neglect. Evaluation results confirmed that the vibration-based system successfully met its objectives—improving user safety as an alternative to conventional alerts while demonstrating stable and durable performance. The system shows promising potential for broader implementation, particularly in automotive safety applications.
