    INTRODUCTION

    1.1 MOTIVATION

    Driving is complex and challenging. A simple way to make driving safer is to reduce

    the number of non-driving and distracting activities you undertake while driving.

    Research shows that dialing and talking on a mobile phone while driving can lead to

    Riskier decision making

    Deciding when it is safe to turn in traffic is a complex task. Using a mobile phone

    while driving affects judgment and concentration and you may fail to choose a

    safe gap. When making a decision to turn across oncoming traffic, you also tend

    not to consider the environmental conditions such as, when it is raining or the

    roads are slippery. If you dont make safe turns you could crash.

    Slower reactions

    You generally react slower when using a mobile phone, particularly when youre

    deep in conversation. You may take longer to respond to traffic signals or

    completely miss them.

    Slower and less controlled braking

    During a mobile phone call your brake reaction time is slower, and you break

    with more force and less control which results in shorter stopping distances

    available between yourself and the car in front.

    Wandering out of your lane

    Youre more likely to wander out of your lane when youre using a mobile phone,

    even on a straight road with little traffic.

    Not being alert to your surroundings

    When using a mobile phone, you tend to spend less time checking your mirrors

    and whats going on around you. This affects your ability to monitor and

    negotiate traffic safely.

    1.2 PROBLEM DEFINITION

    In the fast-paced society of today, we are focused on arriving at our destination as

    quickly as possible. However, with this lifestyle, we are not always aware of all the

    dangerous conditions that are experienced while operating an automobile. Factors such as

    sudden vehicle maneuvers and hazardous road conditions, which often contribute to

    accidents, are not always apparent to the person behind the wheel. In recent years, there has

    been tremendous growth in smart phones embedded with numerous sensors such as

    accelerometers, Global Positioning Systems (GPSs), magnetometers, multiple microphones,

    and even cameras. The scope of sensor networks has expanded into many application

    domains such as intelligent transportation systems that can provide users with new

    functionalities previously unheard of Experimental automobiles in the past have included

    certain sensors to record data preceding test crashes, After analysis, crash scenarios are

    stored and analyzed with real-time driving data to potentially recognize a future crash and

    actually prevent it. With more than 10 million car accidents reported in the United States

    each year, car manufacturers have shifted their focus of a passive approach, e.g., airbags, seat

    belts, and antilock brakes, to more active by adding features associated with advanced driver-

    assistance systems (ADASs), e.g., lane departure warning system and collision avoidance

    systems. However, vehicles manufactured with these sensors are hard to find in lower priced

    economical vehicles as ADAS packages are not cheap add-ons. In addition, older vehicles

    might only have passive safety features since manufacturers only recently began to introduce

    an effective driver assist. Since sensors ultimately add onto the cost of a vehicle initially and

  • Safe Driving Using Mobile Phones

    DEPARTMENT OF ECE Page 3 VYCET

    cannot be affordably upgraded, we target a mobile Smartphone as an alternative device for

    ADASs that can assist the driver and compliment any existing active safety features. Given

    its accessibility and portability, the Smartphone can bring a driver assist to any vehicle

    without regard for on-vehicle communication system requirements.

    1.3 OBJECTIVE OF THE PROJECT

    In this chapter introduction of the SAFE DRIVING USINGMOBILE

    PHONES are discussed. It gives overall view of the project design and the related

    literature and the environment to be considered.

    Chapter wise organization of the thesis and the appendices is given at the end of this

    chapter. At first we discuss the main processing done using ARM7TDMI-S and then what is

    the process that can be automated which is within the scope of the work. Then we discuss the

    implementation aspects.

    1.4 LIMITATION OF PROJECT

    The driver has to place the mobile at the same place when he enters the car.

    The driver has to lift the call manually.

    In this we are not stopping the car we are just reducing the speed to the car to

    10-20 rpm.

    LITERATURE SURVEY

    2.1 EXISTING SYSTEM

    Muting Mobile.

    Voice Mail Converter

    No information to caller

    2.2 DISADVANTAGES OF EXISTING SYSTEM

    Keep some data on existing points

    2.3 PROPOSED SYSTEM

    Automatic attend of the call.

    Gives information about the Driver.

    Only Emergency Call will connect to the User.

    2.4 CONCLUSION

    The former section consists of Ignition Starter; the microcontroller gives the

    signal to the mobile.

    When the signal is received by the mobile it immediately changes in to

    Driving Mode.

    In driving mode, if someone is calling it automatically attends the call and

    gives response only for the emergency call.

    SYSTEM ENVIRONMENT

    3.1. INTRODUCTION

    The flat form for this project is based on Embedded System. An Embedded system is

    a special-purpose system in which the computer is completely encapsulated by the device it

    controls. Unlike a general-purpose computer, such as a personal computer, an embedded

    system performs one or a few pre-defined tasks, usually with very specific requirements.

    Since the system is dedicated to specific tasks, design engineers can optimize it,

    reducing the size and cost of the product. Embedded systems are often mass-produced, so the

    cost savings may be multiplied by millions of items.

    An embedded system is a special-purpose computer system designed to perform a

    dedicated function. Unlike a general-purpose computer, such as a personal computer, an

    embedded system performs one or a few pre-defined tasks, usually with very specific

    requirements.

    Since the system is dedicated to specific tasks, design engineers can optimize it,

    reducing the size and cost of the product. Embedded system comprises of both hardware and

    software. Embedded system is fast growing technology in various fields like industrial

    automation, home appliances, automobiles, aeronautics etc.

    Embedded technology is implemented to perform a specified task and the

    programming is done using assembly language programming or embedded C. Ours being a

    developing country the power consumption is increasing on large scale to meet the growing

    need of the people. Power generation is widely based on the non-renewable sources and these

    sources being depleting some means have to be found for power saving.

    3.2. DESIGN OF EMBEDDED SYSTEMS

    Intelligent, programmable and computing electronic device designed to perform

    specific tasks based on a fixed time frame. An embedded system is a combination of

    hardware and software, perhaps with some mechanical and other components designed to

    perform a specific task.

    Figure 3.1 Embedded System Design.

    Electronics usually uses either a microprocessor or a microcontroller. Some large or

    old systems use general-purpose mainframes computers or minicomputers.
