Abstract The most common problem that is faced in India is the maintenance of roads. The maintenance of roads mostly focusses on improper roads which are due to potholes, humps etc. Our project mainly aims at detection of potholes and humps to avoid accidents & at the same time damage to the vehicle. We have used ultrasonic sensors for measuring the depth & height of the road surface.

The data which are sensed by the sensors include the depth of the potholes & height of the hump & geographic location which is to be already stored in the database. This information serves as a valuable source to the government authorities i.e PWD office and vehicle drivers via GSM. Keywords- Accelerometer, Ultrasonic Sensor, LCD, GSM, GPS

I. INTRODUCTION India is one of the most popular country in the world and it has a fastest growing economy. Roads are the dominant means of transportation in India today. However, in India most of the roads are narrow and congested. It has a poor surface quality and less maintenance. Since we are in India driving is a breath holding, potentially threatening affair. Vehicle population has been increased tremendously over the last two decades. Nowadays traffic congestion and road accidents are increasing mainly due to this proliferation of vehicles.[4]. According to the survey report “Road Accidents in India, 2011�, a total of 1, 42,485 people had lost their lives due to fatal road accidents by the ministry of road transport and highways[4]. These speed are unevenly distributed with unscientific heights. Heavy rains and movement of heavy vehicles are the main reasons for the formation of potholes. This also leads to major traumatic accidents and loss of human lives. The major benefit of our project will be in rainy season as this will be very helpful to take an action to furnish better road quality, as the bad roads will be detected by our system .We mainly focus on detecting pothole, Humps and vehicles which come across while driving.

II. PROBLEM STATEMENT One of the increasing problem roads face are worsened road conditions .Unexpected hurdles on the roads may cause huge number of accidents , Also because of bad road conditions fuel consumption of vehicles increases ,causing wastage of precious fuel. All these reasons urge that it is important to get information of such bad road conditions, collect and distribute it to vehicles, which in turn can warn the driver. Pothole detection system is a system that aims at collecting information, sending and storing it to the PWD and warning the driver about the uneven roads and potholes in its path.

III. OBJECTIVES The significance of our paper is to provide the best utilisation of our system to protect the users from accidents by sending the information to the authorities which will simply maintain the roads which will thereby reduce the number of accidents and hence cause no damage to humans nor vehicles.

This paper highlights the use of ultrasonic and accelerometer sensors in order to detect the potholes coming ahead the vehicles and inform the user vehicle about the potholes via GSM SIM900A in order to take precautionary actions to avoid accident.

The accelerometer sensor is a three axis sensor which has a bandwidth of 0-50Hz and helps detect the potholes with its tilt detection mode and hence is easy to use. [6] All rights reserved by www.grdjournals.com

IV. PROPOSED METHODOLOGY In our project we are using PIC18F4520 which is a 40 pin microcontroller with 32k bytes program memory. Microcontroller is the heart of the proposed system and is responsible for performing various tasks starting from processing all the sensor inputs to alerting the driver.

A. Ultrasonic Sensor HC-SR04 is an active ultrasonic sensor and contains a transmitter and a receiver. It is used to measure distance at which humps are present in front of it. The ultrasonic sensor transmits high frequency sound waves and waits for the reflected wave to hit the receiver. ULTRASONIC SENSOR- Ultrasonic sensor are basically used to measure the distances between the object place in front of it and the sensor. The ultrasonic sensor works on Doppler Effect. [2.]

The distance is calculated based on the time taken by the ultrasonic pulse to travel a particular distance. HC-SR04 works at 40 KHz frequency and can measure distance of objects in the range 2-400cm with a 15o angle of detection.

B. GPS Receiver The global positioning system GPS is a satellite navigation system and is used to capture geographic location, it is maintained by the U.S. Government and is freely available to anyone who has a GPS receiver. It obtains the GPS information from satellites in National Marine Electronics Association (NMEA) format. The NMEA has defined a standard format for GPS information, and is followed by all satellites, the standard defines various codes such as GLL-Latitude/Longitude data, GSV-detailed satellite data and RMC-minimum recommended data.

C. GSM Sim 800 Global standards for Mobile Communication (GSM) is a set of standards for Second Generation (2G) cellular networks .The SIM800 is a complete Quad-band GSM/GPRS solution in a SMT type which can be embedded in the customer applications.

SIM800 supports Quad band 850/900/1800/1900MHz ,It can transmit voice, Sms and data information with low power consumption .Featuring Bluetooth and Embedded AT it allows total cost savings and fast time-to-market for customer applications.[2.]

D. Accelerometer Accelerometer is a sensor which converts accelerations from motion or gravity to either analog or digital electrical signals.

The raw data set from the accelerometer is the acceleration of each axis in the units of gravitational force which is convertible to other units also. The raw data is represented in a set of vectors .The acceleration data is collected from pothole and hump respectively, the system collects three axis readings X Y &Z.[6.][7.]

E. LCD The LCD display is a 16 characters, 2 line alphanumeric display .The LCD display requires data in serial format.

F. Buzzer A buzzer or beeper is an audio signalling device, buzzer used in this project is an alarming device, Buzzer is an integrated structure of electronic transducers ,DC power supply ,Active buzzer 5v rated power can be directly connected to a continues sound.

V. IMPLEMENTATION The implementation section consists of the flowcharts for both sensing vehicle as well as user vehicles, both the flowcharts are as shown below:

VIII. CONCLUSION The proposed system basically serves the following purposes: The proposed system will detect the potholes and humps on the road and save the information in the server. The potholes are detected and its height and depth and size are measured using ultrasonic sensors and accelerometer. The GPS is used to find the location of pothole .All the information is saved in the database. This timely information helps recover the road as fast as possible. Also this system measures the distance between two vehicles to avoid road accidents. [2]

IX. FUTURE SCOPE An important aspect of our project is the maintenance of roads which will rapidly make our city a smart city and these developed roads will lead to the safety of human life & this system can be used to benefit the people by using some high level technologies and ideas for the increased development of the roads and prevention from accidents.
