This document describes a speed checker device for highways that monitors vehicle speed and alerts traffic authorities of speed limit violations. The speed checker uses infrared sensors spaced 1 meter apart to measure the time it takes a vehicle to pass between the sensors. It then calculates the vehicle's speed and sounds an alarm if the speed exceeds the highway limit. This allows traffic authorities to be notified of speeding vehicles and helps reduce accidents. The speed checker provides a simple alternative to more complex radar and laser-based speed guns by measuring time of flight between two infrared beams to calculate a vehicle's speed as it passes.

The project mentioned here is Speed checker and over speed detector for Highways. This project is designed and developed by taking into consideration the problem mentioned above. We have used two sensors in this project. These sensors detect the vehicle speed. Condition is that, the two sensors should be installed at a distance of 100 meteres apart from one another.
Now-a-days we hear news about accidents on Highways very frequently. And in most of the cases main reason of accident is overspeed. Although all highways do have signboards indicating maximum speed limit for the sake of drivers safety, but still people does not obey highway speed limit.Wireless Rash Driving Detection System

This document describes a circuit that can be used as a speed checker for highways. The circuit uses two laser-light emitting diodes and light dependent resistors installed 100 meters apart on a highway. As a vehicle passes between the two sensors, timers measure the time taken and use this to calculate the vehicle's speed. If the calculated speed exceeds the legal speed limit, an alarm sounds to alert the driver. The circuit provides a digital display of the vehicle's speed and can be adjusted to check for limits of 40 or 60 kmph.Speed checker on highway using 8051

This paper presents a device to detect the vehicle's speed and recording the image. The major cause of road accident is mostly caused by human speed. The speed of a moving vehicle is determined by using calculation from a particular distance and time as an approach to estimate the vehicle speed. This system is designed to reduce the road accidents in the development of the vehicle speed detector system by using an IR sensor, Camera, 16x2 LCD, buzzer, LED and Arduino UNO. Police stations handle this system for reducing the vehicle's accidents conditions. In this system, two IR LED's transmitter and receiver sensor pairs, which are installed on the highway 27 cm apart, with the transmitter and the receiver of each pair on the same side of the road. The system displays the time taken by the vehicle in crossing the distance from one pair to the other from which the speed of the vehicle is calculated. If a vehicle exceeds the speed limit then LED is ON while the buzzing sound gives an indication to the police stations. The camera is used for recording the vehicle's images and LCD is used to display the vehicle's speed. Arduino UNO is the heart of the system, which controls all the function of the circuit.

Nowadays, vehicular accidents have been increasing from day to day. Most of them are the cause of over speeding. This thesis describes the Arduino based vehicle speed detection system using Doppler radar. The primary goal of this system is to design of the vehicle speed detector using Doppler radar which is used to reduce the amount of accidents caused by over speeding. In this system, continuous wave CW Doppler radar which is a special case that only provides a velocity output is used as a sensor and the microcontroller is used to calculate the speed of the vehicle. Moreover, the amplifier is used to amplify the voltage level to drive the microcontroller as the sensor output is in micro volts. It is also included LCD display to indicate the speed level. A Doppler radar that can determine the frequency shift that occurs in electromagnetic waves due to the motion of scatters toward or away from the observer through measurement of the phase change that occurs in electromagnetic waves during a series of pulses. The Doppler frequency is negative for objects receding from the radar. The Doppler frequency is positive for objects approaching the radar. This system can be acceptable in real time applications because it is independent of temperature, humidity, noise airflow, dust, light, etc. The results of design are tested and follow through realization. Each of the implementation is evaluated and these evaluations lead to the conclusion that the design is able to achieve high accuracy of the speed. The major components of the design are Doppler radar HB100 , Arduino Uno, LCD display and LM324. C programming language is developed in this system. The results of this work can improve the performance of automobile safety system.

This document describes a smart traffic controller system that can adjust traffic light timing based on vehicle volume and give priority to ambulances. It uses infrared sensors to detect vehicle counts and determine congestion levels. When congestion is high, it increases the green light time. It also uses radio frequency transmission for ambulances to remotely trigger a traffic light to turn green as they approach, allowing for priority passage. The system aims to improve traffic flow and save lives in emergency situations.collision warning assistance system

The document describes a collision warning system with automatic braking for vehicles. It works by using sensors like radar and cameras to detect objects in front of the vehicle. If an object is detected and the speed differential suggests a collision is likely, the system automatically activates the brakes. The document outlines how different manufacturers implement such systems and provides examples of specific systems like Collision Mitigation Brake System (CMBS). It also describes how such a system could work on a motorcycle and includes diagrams of example circuits and components used to build an automatic braking system.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.

This document describes a system to automatically control and reduce vehicle speed using RF technology. The system uses RF transmitters mounted in areas like curves to transmit a signal when a vehicle enters that area. Receivers in the vehicle detect this signal and send it to a microcontroller which reduces the fuel flow, slowing the vehicle. This prevents accidents by reducing speed in hazardous areas. The document provides details on the system components, working, applications, advantages and conclusions.Automatic braking system

This document describes an automatic braking system for vehicles that uses ultrasonic sensors to detect obstacles and apply the brakes autonomously. The system consists of an ultrasonic sensor with transmitter and receiver, a microprocessor, DC gear motor, servomotor, and braking components. It works by transmitting ultrasonic waves from the sensor transmitter and detecting reflections from obstacles with the receiver. The microprocessor analyzes the sensor data and controls the servomotor, which applies the brakes through the braking system if an obstacle is detected within a certain distance from the vehicle. This automatic braking system is intended to prevent accidents by braking the vehicle automatically if the driver is unable to brake manually in time upon detecting an obstacle.autonomous obstacle avoiding car robot with two wheel using arduino

A driverless car is a vehicle that can drive itself without human assistance through the use of an autopilot system. It uses sensors like LIDAR, video cameras, distance sensors, and position estimators to detect traffic lights, nearby obstacles, and the vehicle's location to navigate autonomously. Potential benefits include increased safety, mobility for those unable to drive, and reduced traffic. However, disadvantages include security risks from hackers potentially interfering with the vehicle's systems and sensor failures increasing accident risks.Automotive radar in english

This document describes a system for automated speed control of vehicles using RF transmitters and receivers, GPS, and collision detection sensors. The system aims to replace speed breakers and autonomously limit vehicle speed in designated safe zones. It uses RF signals to control speed when a vehicle enters an area and GPS coordinates to define speed zones. An ultrasonic sensor measures distance to detect potential collisions and triggers warnings or forced braking. The system was prototyped and tested, demonstrating redundant speed control and accurate collision detection. The goal is to reduce accidents by automatically enforcing speed limits and preventing collisions.Traffic management near u turns to avoid accidents

The document describes a proposed system to manage traffic near U-turns to prevent accidents. The system uses sensors placed on both sides of the road near U-turns to detect vehicles turning. When a vehicle is detected turning, a signal is sent to controllers to display red lights on the opposing side to slow or stop traffic. Once the turning is complete, the signal resets to green. Lasers and buzzers are used to detect and notify authorities of any traffic violations. The proposed system is low-cost and easy to implement in real-time using an Arduino board and various sensors. It provides a simple way to avoid collisions at turns and control traffic flow.Speed cameras ppt full ...

SPEED OF VEHICLESSpeed checker for highways
- 1. SPEED CHECKER FOR HIGHWAYS INTRODUCTION While driving on highways, motorists should not exceed the maximum speed limit permitted for their vehicle. However, accidents keep taking place due to speed violations since the drivers tend to ignore their speedometers. So some system is required which will inform the traffic control unit about such vehicles exceeding the speed limit to avoid accidents on the highway. This speed checker will come handy for the highway traffic police as it will not only provide a digital display in accordance with a vehicles speed but also sound an alarm if the vehicle exceeds the permissible speed for the highway. As soon as a fast moving vehicle exceeds the speed beyond the specified limit, an alarm is sounded and traffic control unit will be informed about the vehicle. Thus by using this system, we can manage to control the accidents occurring on highways and ensure drivers safety. SPECIFICATIONS Operating voltage : 5 volts DC Sensors used : IR LEDs Distance between sensors : 1m Alarm rating : 5V DC Minimum speed : 2 kmph Maximum speed assumed : 200kmph Box dimensions : 300 mm x 100 mm x 150 mm Supply : 230 V, 50 Hz AC LITERATURE SURVEY: In market today many speed guns are available which use RADAR, which works by bouncing a microwave frequency of a moving object & measuring distance in the transmitted, & returned frequency, this is called Doppler Shift. If the returned frequency is higher than transmitted frequency called a compressed the vehicle is approaching the RADAR gun. If the returned frequency is lower called stretched the target vehicle is going away from RADAR gun. In a laser speed gun measure the round-trip time for light to reach a car and reflect back. A laser speed gun shoots a very short burst of infrared laser light & then waits for it to reflect off the vehicle. The gun counts the number of nanoseconds it takes for the round trip & by dividing by two it can calculate the distance to the car. But unlike the above-mentioned complicated methods of speed tracking, we have used relatively simpler technique to calculate the speed of any vehicle. We have two IR beams each of them facing a infrared light sensor. As soon as first beam of light is intercepted an interrupt will be generated. This will trigger the timer. Then as soon as second beam is intercepted the timer will be stopped. Knowing the distance between two sensors and the time elapsed we can easily calculate speed of the vehicle. This speed will be processed by the microcontroller to check whether it is in the specified limits. THIS PROJECT'S MORE INFORMATION WILL BE POSTED SOON>>>.....
