Design And Construction Of A Car Overspeed Detection Weight Sensor

ABSTRACT

This work is on a device to detect rash driving on highways and to alert the traffic authorities in case of any violation. In past, lot of devices to detect rash driving on highways has been made.

Most of the approaches require human concentration and involve a lot of effort, which is difficult to implement. In this paper we intend to design a system aimed at early detection and alert of dangerous vehicle driving patterns related to rash driving. The speed limit is set by the police who use the system depending upon the traffic at the very location. The time taken by the vehicle to travel from one set point to the other is calculated by control circuit and displays that on seven segment displays. Moreover, if the vehicle crosses the speed limit, a buzzer sounds alerting the police.

 CHAPTER ONE

1.1                                                        INTRODUCTION

While driving on highways, motorists should not exceed the maximum speed limit permitted for their vehicle. However, accidents keep occurring due to speed violations since the drivers tend to ignore their speedometers.

Rash driving is the cause of many road accidents all over the world. The traffic population has increased considerably in Nigeria as there is no means to control or monitor the speed of vehicles running on roads. This system proves highly effective in detection of overspeed driving. It is not at all necessary that such accidents are results of driving under the influence of alcohol as even a person who hasn’t consumed alcohol can drive in a reckless manner [3]-[5]. To overcome this problem and decrease death rate due to accidents, introduction of new and innovative speed enforcement technology is necessary

Nowadays, rash driving causes a serious danger to the driver as well as general public. Despite the fact that rash driving is a serious problem, its current methods of detection by patrol officers lack sufficiency [6], [7].

First of all, given the huge mileage of driveways, the number of patrol officers is far from enough to observe and analyze every driver’s behaviors. Second, the guidelines of rash driving patterns are only descriptive and visual observations cannot specify the details of driving at night or in poor weather.

In the present system, to detect rash driving police has to use a handheld radar gun [8],[9]and aim at the vehicle to record its speed. If the speed of the vehicle exceeds the speed limit, the nearest police station is informed to stop the speeding vehicle.

This is an ineffective process as after detecting one has to inform the same and a lot of time is wasted. With the number of vehicles increasing day by day, this method cannot be trusted with the lives of people.  A wide range of sensor technologies are also available, such as inductive loops, video, ultrasonic detectors, microwave detectors and radar based detectors [11].

The history of speed enforcement is replete with examples of new enforcement techniques; subsequent negative public reaction and resistance; and finally,  assuming survival through legal challenges to these techniques.

The advantage of over speed driving warning system is that it will come handy for the highway traffic police as it will not only provide a digital display in accordance with a vehicle’s speed but will also sound an alarm if the vehicle exceeds the permissible speed for the highway.

The proposed system will check on rash driving by calculating the speed of a vehicle using the time taken to travel between the two set points at a fixed distance. A set point consists of a pair of sensors comprising of an IR transmitter and an IR receiver, each of which are installed on either sides of the road. The speed limit is set by the police who use the system depending upon the traffic at the very location. The time taken by the vehicle to travel from one set point to the other is calculated by control circuit. Based on that time, it then calculates the speed and displays that on seven segment displays. Moreover if the vehicle crosses the speed limit, a buzzer sounds alerting the police. This concept can be extended in future by integrating a camera with the system which could capture the image of the number plate of the vehicle to sends that to the traffic authorities.

1.2                                             OBJECTIVE OF THE PROJECT

The objective of this work is to provide a digital display in accordance with a vehicle’s speed but also sound an alarm if the vehicle exceeds the permissible speed for the highway using weight sensor

1.3                                         SIGNIFICANCE OF THE PROJECT

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 driver’s safety, but still people does not obey highway speed limit. This speed checker will come handy for the highway traffic police as it will not only provide a digital display in accordance with a vehicle’s speed but also sound an alarm if the vehicle exceeds the permissible speed for the highway.

1.4                                                 SCOPE OF THE PROJECT

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 meters apart from one another. Liquid Crystal Display (LCD display) is connected to this project. This display will show the vehicle speed. It will also intimate user if vehicle speed crossed the maximum speed limit or not. The project also has a Buzzer. Overspeed condition is indicated by turning on the Buzzer.

1.5                                          APPLICATION OF THE PROJECT

1. This can be used at Highways (National Highways, State level Highways).
2. This project can also be used inside university campus areas or inside any company’s premises.

1.6                                           LIMITATION OF THE PROJECT

• This project is valid for sequential flow of vehicles.
• It is only for one-ways.

1.7                                                 FUTURE DEVELOPMENT

1. A CCTV Camera can be placed on the highway. If any vehicle has crossed the maximum speed limit then this camera will be triggered to take a picture of the vehicle.
2. We can add voice announcement system. It will intimate the driver that he/she has crossed the over speed condition.
3. We can implement the GSM technology. So that the nearest highway security authorities will be informed about the vehicle which has over speed.

1.8                                        PROJECT WORK ORGANIZATION

The various stages involved in the development of this project have been properly put into five chapters to enhance comprehensive and concise reading. In this project thesis, the project is organized sequentially as follows:

Chapter one of this work is on the introduction to this speed checker. In this chapter, the background, significance, objective limitation and problem of this speed checker were discussed.

Chapter two is on literature review of this speed checker. In this chapter, all the literature pertaining to this work was reviewed.

Chapter three is on design methodology. In this chapter all the method involved during the design and construction were discussed.

Chapter four is on testing analysis. All testing that result accurate functionality was analyzed.
