1. INTRODUCTION

   Motorcycle safety has become a critical concern due to the high risk of fatalities associated with accidents. Various advanced technologies and crash detection systems have been developed to improve rider protection and enhance road safety. Modern solutions use Inertial Measurement Units (IMUs) to monitor parameters like roll, pitch, and yaw, employing data processing techniques for improved accuracy and responsiveness. IoT-enabled systems incorporate tilt sensors and GSM/GPRS modules to automatically send emergency alerts with precise location data, drawing power directly from the motorcycles battery for efficiency. Additionally, smart helmets integrate GSM and GPS technology to detect crashes, enforce helmet usage, and monitor alcohol consumption,

   preventing unsafe riding behavior. These compact, reliable, and cost-effective solutions are particularly valuable in

   regions with high motorcycle usage. Future advancements may leverage machine learning and video analytics to further improve detection accuracy and reduce response times, contributing to a significant reduction in accident-related fatalities. This paper reviews key developments in crash detection and alert systems aimed at enhancing motorcycle safety and minimizing losses.

2. RELATED WORKS

   1. IoT-based Accident Detection and Emergency Alert System for Motorbikes

      This paper [1] proposes an IoT-enabled accident detection system for motorcycles that sends emergency notifications to designated contacts. The system uses a tilt sensor to monitor the bikes inclination and triggers alerts via SMS and GPRS when a critical tilt angle is exceeded, ensuring swift assistance. Designed for efficiency, it draws power directly from the motorcycles battery, eliminating the need for additional power sources. Core components include an MPU-6050 accelerom- eter for tilt measurement, an Arduino Nano microcontroller for data handling, and a SIM800L GSM module for wireless communication. Power regulation is managed using a voltage stabilizer to optimize energy use. The system underwent extensive testing on various motorcycle models, establishing a safe tilt threshold of 40 degrees. This cost-effective solution is particularly beneficial in regions where motorcycles are com- mon. Future improvements may incorporate GPS for precise location tracking, ultrasonic sensors for enhanced accuracy, and a manual emergency button to boost overall safety.

   2. Crash detection using IMU sensor

      This paper [2] introduces a crash detection system for motorcycles using an Inertial Measurement Unit (IMU) sensor, specifically the MPU6050, which integrates both a gyroscope and accelerometer. The system tracks motion parameters such as roll, pitch, and yaw to detect accidents, addressing the unique dynamics of motorcycles compared to cars. The MPU6050s built-in Digital Motion Processor (DMP) minimizes gyroscopic drift and accelerometer errors, enhancing the accuracy of motion data. By combining data from both sensors through techniques like complementary and Kalman filters, the system effectively detects crashes while balancing responsiveness and stability. Unlike the complementary filter, which is sensitive to vibrations, the DMP offers superior performance in high-vibration environments typical of motorcycles. This cost-effective solution aims to reduce emergency response times when integrated with automated alert systems. Future advancements could incorporate more vibration-resistant automotive sensors to improve precision and energy efficiency further.

   3. Smart Helmet System with Wireless Communication through GSM

      This paper [3] addresses the aspect for safety of motorcyclists through a development of a helmet which serves to carry out interaction with GSM technology. The strategic point in developing such a system combines it with the use of sensors like vibration and sound sensors. The sensor is read into an Arduino microcontroller, which, in turn, processes real-time data to detect injury by means of an accident. For GSM technology, all this is advantageous in monitoring a situation of a young smart helmet system. After a fall and process of falling detection, a very exact location from the GPS along with information to contact emergency services would be sent, as mentioned above. Its battery is directly powered from the motorcycle, meaning that the device will not require a rechargeable cell line to be plugged in place and imparts the never-ending functions. Further benefitting very much to that of a GPRS module is making the data sending easened to far- off areas through it, while the GSM module could trigger the alert by triggering an alert on time. The system was designed to be compact in terms of size, cost-effective, and highly reliable in its functionality and is therefore suited to the third world where motorcycles are a common mode of transportation. Furthermore, possible future improvements in this regard also involve the integration of additional useful features, an incorporation of a machine- learning algorithm that significantly improves the systems performance, thus allowing the operator to obtain access to real-time informatio .

   4. Smart Helmet With Message Alert System

      This paper [4] Intergrates into a smart helmet system to prevent the accidents and also helps for the emergence rescue for riders. It employs sensors to monitor helmet-wearing and alcohol abuse to prevent the rider from firing up the scooter under adverse conditions. It features an accident detection mechanism, wherein in the event of an accident sensors on the vehicle trigger a GSM-based alert and sends an SMS with GPS location to pre- defined contacts. The helmet interface and vehicle modules communicate through RF technolgy and control functions are managed by a microcontroller. This is a solution toin order to reduce the accidents.

   5. Smart Helmet Using GSM and GPS Technology for Acci- dent Detection and Reporting System

      This paper [5] proposes a smart helmet integrated with GSM and GPS technology to enhance motorcycle safety by detecting accidents and notifying emergency contacts promptly. Equipped with vibration sensors, the helmet identifies crashes and communicates the accidents location via GPS data. It includes features like helmet usage enforcement to prevent drunk driving and ensure safety compliance. This innovative system aims to reduce fatalities by addressing both accident prevention and rapid response, demonstrating its potential to save lives in critical situations.

3. PROBLEM STATEMENT

   Motorcycle accidents pose a significant safety challenge, often leading to severe injuries or fatalities due to delayed emergency response and a lack of effective prevention mechanisms. Traditional safety measures fail to address the unique dynamics of motorcycles compared to other vehicles. This has driven the development of advanced crash detection systems and smart safety technologies. Key issues include accurately detecting crashes in high-vibration environments, monitoring rider behavior such as helmet usage and ensuring real-time transmission of alerts with precise location data. Efficient power management, cost-effectiveness, and adaptability to diverse road conditions remain critical challenges. Addressing these gaps requires integrating sensors, IoT-enabled communication modules, and data processing techniques to enhance detection accuracy, improve response times, and ultimately reduce accident-related fatalities. This survey aims to explore current advancements in smart crash detection and alert systems, emphasizing innovative solutions designed to mitigate motorcycle accident risks and improve rider safety.

4. LIMITATIONS

   Limitations of Smart Helmets for Accident Detection

   1. False Alarms & Sensitivity Challenges : Minor impacts, such as dropping the helmet or accidental knocks, can trigger false accident alerts. Some systems may not effectively detect low-impact collisions.
