Abstract

In this era of globalization, road accident is a global tragedy with the ever-rising trend. The number of accidents increasing year to year due to several causes such as a blind spot, adverse weather conditions, landslides, and road conditions especially at the curve or sharp roads which mostly located at mountains and hills. Therefore, the purpose of this project is to design and develop a blind spot indicator system in order to minimize the number of collision and death at the curve or sharp roads. The objective of this project is to design and develop a blind spot indicator traffic system and fog or mist situation detector to avoid accidents and crashes at curve roads, to develop a system to detect an accident at curve roads and alert the drivers by using IoT and to establish a landslide or inclined plane detector at the edge of the blind curve to alert the drivers. This blind spot indicator system used an Arduino Mega as a main controller with additional NodeMCU esp8266 for wireless communication. Furthermore, this system consists of ultrasonic sensor, temperature and humidity sensor, tilt sensor, and vibration sensor. Ultrasonic sensor is used to detect the presence of vehicles at curve road while the temperature in Celsius and the humidity rate in percentage are being sensed by DHT11 sensor. Besides that, tilt sensor is used to detect the landslide or inclined plane. Vibration sensor is used to detect accidents happens at the curve road. In addition, an alert message using Internet of Thinking (IoT) has been designed using ThinkSpeak platform and IFTTT services. From the results, the hardware circuit in the prototype was run smoothly as the simulation circuit and all the inputs and output displays were working well. The speed for the vehicle approach to the corner of the prototype also been predicted and tabulated to help real time implementation. In a nutshell, this project is easy to use and will be a better improvement to the blind spot system at a curve road.
