Road accident due to overspeeding is a common occurrence in a developing nation such as Nigeria. Therefore, the need for a device capable of notifying a vehicle driver when the allowed speed limit of an area is exceeded arises. In this work, a microcontroller based automobile speed limiting device and alarm control system was designed and developed. The core components employed for the system design include Arduino Nano microcontroller, 1602 liquid crystal displays (LCD) module, light-emitting diodes (LEDs), buzzer, 18650 battery, I2C, infrared detectors and push buttons. Data gathering and circuit designs were implemented with microcontroller as focal point using suitable design models. Performance test was carried out on the developed system and the device's reading error was determined. The developed automobile speed limiting device and alarm control system was functional and performed satisfactorily during testing. The reading error of the device was evaluated as 5.83%. The developed speed limiting device, apart from being suitable and efficient for vehicle speed measurement, could also be deployed for general applications requiring speed measurement.

The problem of exceeding the posted speed limit on roads typically leads to a high percentage of accidents and fatalities each year in most developed countries. Unless the vehicle's speed can be limited or controlled, drivers are able to drive at dangerously high speeds, risk lives, and attract costly speeding ines after being photographed by a 'speed camera'. This may happen due to lack of awareness of the current speed limit in a particular area, or drivers not being careful enough to check their current vehicle speed. This paper describes a prototype system that can help reduce the over-speeding problem by itting a transmitter on road signs and a receiver on vehicles. A maximum speed limit data signal is broadcasted continuously from a road sign, and a vehicle itted with a wireless receiver module can detect the speed limit signal. The system can compare the vehicle's current speed with the speed limit and trigger an audible alarm (and alert message) to indicate that the speed limit has been exceeded. A working prototype has been designed, built and tested successfully using an 8-bit embedded microcontroller. Using appropriate transceiver modules, it is possible to implement Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communications in order to implement a wide range of different and useful functions, including collision detection, vehicle identi ication and even the processing of ines for traf ic rule violations. This paper describes the design details of an over-speeding warning system and addresses several other practical applications of wireless technologies for improving road safety. It is hoped that this research will encourage further research into V2V and V2I applications by demonstrating how low-cost wireless communications modules and low-cost microcontrollers can be used to perform several different useful functions. If products like the devices described in this paper are marketed and sold, they could save lives and promote safer driving by simply annoying or constantly warning drivers who exceed the current speed limit, using a loud audible alarm which cannot be disabled by the driver, and warning of nearby dangers.

Driving or Riding a vehicle in India is by large becoming a dangerous experience. Of Worldwide annual average of 70,000 road accidents, 10 percent occur in India. The latest annual statistics indicate that over 80,000 people are killed on Indian roads due to not following the traffic regulations by the driver. The project addresses this serious issue and proposes a low-cost dynamic electronic speed monitoring unit. The proposed project comprises of hardware design using a low-cost 8-bit AT89S52 microcontroller and the complete hardware design will be proposed which will continuously monitor the speed of the vehicle and senses the other vehicles which are going front and back, computing the distances of the vehicles during the journeys. The embedded software design is proposed using keil µ vision 4IDE that will continuously update the accidental danger zone threshold limit in front and back. The system uses an IR sensor based hardware design connected to the 8-bit CPU for real-time speed adjuster and threshold mapping. A relay indicator is connected to alert the driver if any vehicle is running on either side of the vehicle, within the threshold danger limit. The system design uses various debugging tools such as Null modem checking, Keil µ vision 4C51 debugger and serial debugging utilities are used for testing the design during the implementation phase.

In the present day scenario traffic rules are frequently violated by the drivers and over speeding occur due to bad driving behavior. So, a driver assistance system is provided to prevent over speeding, violation of road rules and also to display alert messages. The proposed system has an alerting, recording and reporting system for over speed violation management. The Zigbee transmitter sends the speed limit of the particular lane entered by the vehicle and also gives alerts like “road works”, “steep slopes”, “school zone” in the form of acoustical messages and also in LCD. The receiver unit placed in the vehicle receives the messages and sends to the microcontroller. When speed of the vehicle nears the speed limit it displays the warning and if exceeds the limit, the microcontroller records the violated speed and time. The LCD displays the lane speed limit and shows the number of times, speed was violated. A GSM module sends message to the nearest traffic personnel immediately aft...

This paper explores the possibility of providing traffic control signals through radio frequency (RF) transmission or by other means of wireless data communication and thereby reduce road accidents. Additional advantages can be reducing the car speed or stopping car at speed breakers, no entry zones or police barricade. This system if adopted by some state can effectively reduce the number of road accidents caused by speeding vehicles Losing control of the vehicle at speed breakers or by driver's negligence towards traffic signals. The primary model of this system consists of a microcontroller controlled RF transceiver module, electronic controller unit (ECU) used in vehicles. In the system proposed the traffic sign boards including control signals are replaced with RF transmitters transmitting the specified coded data(about the traffic signal) for the traffic control receiver unit integrated in the in the car where the receiver unit is connected to the ECU and to display unit on the dashboard of the car which on coming in vicinity of the particular traffic signal transmitter starts displaying the very traffic signal on the displaying unit. For some specific signals, of the likes of speed breaker, police barricade it asks for response for the driver in specified time duration such as to reduce speed or stop down, if the driver does not respond in the required manner the controller unit takes control of car transmission and performs the specified operation.

Digital Technologies and Applications

Every year, millions of people around the world die from road accidents, excessive or unsuitable speed is one of the main factors responsible for accidents, and it is implicated in a third of deaths. The main objective of this paper is to follow the driver from the speed of the vehicle as well as to know his behavior and his physical state on the roads to reduce the risk of accidents. In this paper, we monitor the instantaneous speed of the vehicle using a control system that can be mounted in any vehicle equipped with the OBD-2 protocol (on-board diagnostics). A monitoring chain based on a PIC microcontroller will be mounted in the vehicle as well as other peripherals such as an SD memory card module, a GPS geographic positioning sensor, a shock sensor and a global system for mobile communications GSM module. Unauthorized speed and the location data of the vehicle will be recorded in the SD memory card with accurate date and clock. In the event of an accident, an emergency message containing the latest speed and position data will be sent through the GSM module to the nearby medical center and local police as well as to the operator or owner (in case of car rental).

The Rapid growth of technology and infrastructure has made our lives easier. The advent of technology has also increased the traffic hazards and the road accident take place frequently which causes huge loss of life and property because of the poor emergency facilities. Our project will provide an optimum solution to this draw back. An accelerometer can be used in a car alarm application so that dangerous driving can be detected. It can be used as a crash or rollover detector of the vehicle during and after a crash. With signals from an accelerometer, a severe accident can be recognized. According to this project when a vehicle meets with an accident immediately Vibration sensor will detect the signal or if a car rolls over, and Micro electro mechanical system (MEMS) sensor will detects the signal and sends it to ARM controller. Microcontroller sends the alert message through the GSM MODEM including the location to police control room or a rescue team. So the police can immediately trace the location through the GPS MODEM, after receiving the information. Then after conforming the location necessary action will be taken. If the person meets with a small accident or if there is no serious threat to anyone`s life, then the alert message can be terminated by the driver by a switch provided in order to avoid wasting the valuable time of the medical rescue team. This paper is useful in detecting the accident precisely by means of both vibration sensor and Micro electro Mechanical system (MEMS) or accelerometer. As there is a scope for improvement and as a future implementation we can add a wireless webcam for capturing the images which will help in providing driver`s assistance.
