ABSTRACT The main aim of this project is to design a system for implementing an efficient over speed and alcohol detection system for vehicles that will be useful to reduce car accidents. Now a days, car accident reaches in an alarming rate. Accident occurs due to many reasons. From those, most of accidents happen due to over speed and drunken driver problem. There are laws to punish over speed and drunken drivers but this rules and regulations cannot have any system that can reveal the speed status of the car and the driver alcoholic condition. So, there is a need of an effective system to limit the speed of the vehicles and check the drunken drivers. These system works when the vehicle moves beyond the allowed speed, it retrieve to a desired speed and when the vehicle driven by a drunken person then the system automatically send a message to the nearest traffic police station. Therefore the project members will design and implement the prototype of this system.

CHAPTER 1 INTRODUCTION 1.1 Introduction At this time, one of the major factors for loss of life, loss of infrastructures and materialsis a car accident. Even though many quality roads are built, relatively latest car exists, different rules and regulations are made statistically the car accidents are increasing year after year. The reasons for these accidents are many failures to give way for pedestrians, over speed, influence of alcohol and drug are the common and major ones. Starting from this point of view we designed a system which can reduce the accidents caused by over speed and drunken driving. 1.2 Problem statement In our world car accident increases from day to day because of many reasons. From those reasons most car accidents occur due to drunken driving and over speed. Therefore this project will be a solution to the problem by providing an embedded system, which installed in the vehicles. 1.3 Project objective The main objective of this project is to design and implement over speed and alcohol detection system for vehicles. Specific objectives:

To protect the great human life from car accident



To avoid loss of materials and

 To give a better car accident prevention system to the traffic station. 1.4 Scope of the project The project includes design and implementation of both hardware and software. 

Microcontroller (PIC 16F877A) is used as central processor.



Color sensor is used to detect the painted color on the road.



MQ-3 Alcohol sensor is used to detect the alcohol concentration.



RF Module is used to receive and transmit information



The Serial communication precedes using RS232 cable. 10



C– language for the Microcontroller and MySQL Server 2008 for the data base



Micro C and Proteous is used for simulation purpose.

CHAPTER 2 LITERATURE REVIEW To design a system that can achieve the objective of the project some studies have been carried out, which involving three main subtopics such as previous case study on related projects, studies of hardware and software. 2.1 Work review There are some existing projects related to over speed and alcohol detection system. Some of them are:In Ankita Mishra [1] “Design of RF based speed control system for vehicles”, The system has Smart Display controller meant for vehicle’s speed control and monitors the zones, which can run-on an embedded system. Smart Display &Control (SDC) can be custom designed to fit into a vehicle’s dashboard, and displays information on the vehicle. The project is composed of two separate units: zone status transmitter unit and receiver (speed display and contr...
