An efficient automotive collision avoidance system for indian traffic conditions
Abstract The execution of a wide-ranging accident cautioning system is being visualised by ACAS Program, which is proficient in perceiving and cautioning the driver of potential hazard conditions forward, on the side, and rear sections of the vehicle. The structure would use: (a) long array sensor or visual devices to identify probable hazards in front of the vehicle, (2) short range sensors to caution the driver of nearby objects while changing traffic lanes or backing up, and (3) a track exposure arrangement to alert the motorist when the vehicle deviates from the intended traffic lane. Accident Prevention organisms, as a consequent step to collision mitigation, are one of the Great challenges in the area of active safety for road vehicles. The task of a collision avoidance system is to track objects of potential collision threat and govern any action to evade or diminish a crash. The main focus is how to make decisions based on ambiguous evaluations and in the presence of numerous hurdles. The first step in CA (Collision Avoidance) systems for automotive applications is adaptive cruise control (ACC). The ability of the car to protect its passengers is sometimes called crashworthiness. Generally, a CM (Collision Mitigation) system tries to reduce the severity of the accident as much as possible under some constraints. The situation may be observed with detector sensors, laser radar, vision sensors, ultrasonic sensors, GPS sensors and inter-vehicle communication. FCM (Forward Collision Mitigation) systems mainly try to avoid or mitigate frontal collisions. The CA decision is based on the current position estimate of the host vehicle and those of other objects. The focus is towards the method for determining the threat of a collision given that the state of other objects is known. Two collision mitigation by braking systems are considered for study. One system uses the probability of collision, to decide when to perform braking interventions. The other system has a multiple obstacle decision. The scenarios that are calculated in this segment are primarily those where a CMbB has a large potential of significantly reducing the collision speed. Therefore, the test results of main interest is those between 0 and 70 km/h also for simulations. Hence, this ACAS Program detects the potential hazards, warns the driver and takes action to avoid or mitigate a collision.

Adaptive cruise control’
The document discusses adaptive cruise control (ACC) systems, which use sensors and controllers to maintain a safe distance from the vehicle ahead.

Cooperative ACC (CACC) allows vehicle-to-vehicle communication to coordinate speeds and braking more safely. While CACC promises increased safety and efficiency, its benefits require widespread adoption and it may encourage driver complacency. Researchers continue working to develop more advanced safety systems using sensors and vehicle communication.

The system uses an IR transmitter and receiver to detect when the driver's eyes are closed as a measure of drowsiness. When the eye blink count is low, indicating potential drowsiness, an alarm is activated and the pneumatic braking system applies the brakes to help prevent accidents from occurring. The goal of the system is to improve safety by providing an automated braking response based on the driver's eye blinks to help maintain a safe distance between vehicles.
Airbag system for 2 wheeler vehicle system
This document describes an airbag system for two-wheeled vehicles. The system uses sensors to detect collisions and angle of impact, which triggers canisters to rapidly inflate airbags on both sides of the vehicle. This is intended to cushion the rider from bodily harm in an accident by preventing them from being thrown from the vehicle or sustaining head injuries. The inventor estimates the system could reduce fatality rates from accidents by 20-30% by providing greater protection to the rider.
Automatic pneumatic bumper
The document describes an automatic pneumatic bumper system for vehicles. The system uses an IR sensor to detect obstacles in front of the vehicle. When an obstacle is detected, the IR sensor sends a signal to activate a pneumatic cylinder and solenoid valve. This causes the pneumatic bumper to extend out and protect the vehicle from damage on impact. It also cuts power to the vehicle's motor, engaging the brakes to stop the vehicle and prevent an accident. The system aims to reduce accidents by automatically detecting obstacles and activating braking and protective measures.
IRJET- Anti-Collision System with Safety Impact Reduction System
This document describes an anti-collision system for vehicles that uses infrared sensors to detect obstacles and activate both brakes and extended bumpers to reduce damage during a collision. The system includes infrared sensors at the front and rear that can detect objects and signal a control unit. The control unit then activates solenoid valves to deploy pneumatic cylinders that apply the brakes and extend protruding bumpers at both ends of the vehicle. This system aims to provide both pre-crash safety by braking and crash safety by reducing impact through extended bumpers.
Low cost self driven car system
This document proposes developing a low-cost self-driving car system to reduce the over 1.2 million annual road deaths worldwide. It would use sensors like ultrasonic sensors and cameras along with neural networks and AI to process sensory input and control systems like steering and braking. The methodology involves developing, testing, and training the system to recognize situations and communicate between vehicles. The goal is to create a reliable and efficient self-driving system that could help reduce accidents caused by human error and benefit those unable to drive like the blind.
FABRICATION OF AUTOMATIC BRAKING SYSTEM USING ULTRASONIC SENSOR
This document describes the fabrication of an automatic braking system using ultrasonic sensors. It discusses how an ultrasonic sensor attached to the front of a vehicle can detect obstacles and transmit that information to a microcontroller. The microcontroller then controls the speed of the vehicle and applies the brakes based on the distance detected by the ultrasonic sensor, to prevent accidents. It outlines the components used, including the ultrasonic sensor, motor, battery, and Arduino, and describes how they work together in the system to automatically brake the vehicle when an obstacle is detected within a certain distance.
IRJET - Accident Prevention Control System and Detection of Lost Key
This document describes a project to develop an accident prevention and control system using sensors and a microcontroller, as well as a system to detect lost keys using GPS. The accident prevention system uses an ultrasonic sensor to measure distance to nearby objects, and alerts the driver or takes actions like disabling the ignition if distances become too small. If an accident still occurs, the system uses GPS to locate the coordinates and sends an SMS using GSM to emergency contacts. The lost key detection system inserts a GPS module into keys to track their location via a mobile phone app or web page if lost. The system is intended to reduce accidents and provide safety, while having low cost, simple design, and low power consumption.
Accident Alert System using Advance Microcontroller
In India most of the accidents are happening due to vehicles over speeding. Sometimes if obstacle is close to the vehicle then they won't be able to judge the distance to apply instant brakes and accident is occurred. To avoid accident due to over speeding, obstacle detection using ultrasonic sensors is used. In this project ultrasonic sensor is used for 360degree detection of obstacle. If obstacle is in front of the vehicle less than safety distance, automatically brakes will be applied or if vehicle comes from backside of the vehicle and is at less than safety distance then the warning light is shown to vehicle. Sometimes if vehicle is coming very close to our vehicle just before hit the vehicle the airbags are open.

Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

Rainfall intensity duration frequency curve statistical analysis and modeling...
Using data from 41 years in Patna’ India’ the study’s goal is to analyze the trends of how often it rains on a weekly, seasonal, and annual basis (1981−2020). First, utilizing the intensity-duration-frequency (IDF) curve and the relationship by statistically analyzing rainfall’ the historical rainfall data set for Patna’ India’ during a 41 year period (1981−2020), was evaluated for its quality. Changes in the hydrologic cycle as a result of increased greenhouse gas emissions are expected to induce variations in the intensity, length, and frequency of precipitation events. One strategy to lessen vulnerability is to quantify probable changes and adapt to them. Techniques such as log-normal, normal, and Gumbel are used (EV-I). Distributions were created with durations of 1, 2, 3, 6, and 24 h and return times of 2, 5, 10, 25, and 100 years. There were also mathematical correlations discovered between rainfall and recurrence interval.
Findings: Based on findings, the Gumbel approach produced the highest intensity values, whereas the other approaches produced values that were close to each other. The data indicates that 461.9 mm of rain fell during the monsoon season’s 301st week. However, it was found that the 29th week had the greatest average rainfall, 92.6 mm. With 952.6 mm on average, the monsoon season saw the highest rainfall. Calculations revealed that the yearly rainfall averaged 1171.1 mm. Using Weibull’s method, the study was subsequently expanded to examine rainfall distribution at different recurrence intervals of 2, 5, 10, and 25 years. Rainfall and recurrence interval mathematical correlations were also developed. Further regression analysis revealed that short wave irrigation, wind direction, wind speed, pressure, relative humidity, and temperature all had a substantial influence on rainfall.
Originality and value: The results of the rainfall IDF curves can provide useful information to policymakers in making appropriate decisions in managing and minimizing floods in the study area.

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.
