Abstract - In order to utilize the smart phone sensor to estimate the vehicle” speed “, senspeed estimate the natural driving conditions to identify the reference point , it detects the high speed when if the limit exceed, and detects longitude & latitude and also detects when the vehicles drifting, it generating the warning “message” to his/her family reference number for safety purpose. Key Words: Sensing, Acceleration, vehicle speed, urban environments. 1. INTRODUCTION
Nowadays Smartphone based Application of vehicle become more popular to analyze the complexity of traffic in urban area and also it detects the location of the vehicle [2].The Smartphone application uses the embedded system sensors i.e. accelerometer which detects he position, movements and speed of the vehicle. Position indicates left or right, movement indicates the moving straight, Drifting [3]. The author specified that Acceleration accuracy is 90 percent. To enhance driver safety the author proposed a novel system that uses Dynamic Time Warping and Smartphone based sensor-fusion to detection, recognize and record the action [4]. Vehicle tracing ,speed estimation and establishing the distance travelled between initial and final position [5].The author proposed a technique based on Derivation Derivative Dynamic Time Warping algorithm that align a received signal strength trace from a moving cellophane handsets .Detection of the vehicle stopping and presence of location[6]. GPS can be used to locate position or tracing and also Speed of the Vehicle can be obtained from GPS. Usually GPS enabled in all modern Smartphone system, but GPS results in less availability and accuracy. GPS drains or consumes more phone battery and it is hard to obtain accurate vehicle speed relying on GPS for applications requiring real-time or high-accuracy speed estimations. Alternate way for obtaining correct results of estimating speed and location accuracy [2] based on Accelerometer [3]. Accelerometer sensor is available in all Smartphone. The localization method presented here estimates the latitude and longitude by referring x, y axis.
phone’s accelerometer readings along the vehicle’s moving direction over time. Initially acceleration variation can be obtained and later obtaining the speed estimation, total time. Author show the vehicle speed estimation using the accelerometer’s readings of Latitude and Longitude. Compare to GPS changes over acceleration errors is less than GPS. Smartphone sensor eliminates the error and estimates the speed accurately. In our application Senspeed identifies or recognize the reference points of starting, stopping, drifting and also identifies the movement of the vehicle i.e. moving straight, right or left (position of the vehicle). However by using Accelerometer sensor readings can be obtained in the form of latitude and longitude. The advantage of our senspeed application is easy to implement, accuracy is more when compared to GPS and estimation of speed, and total time travelled is easier. Senspeed application is feasible in all platform of Smartphone. [1] Our proposed system over real-driving environments as follows: Initially detects the speed, total time, total distance. Later obtains the Acceleration variations through accelerometer sensor. Implementing Dynamic Time Warping Method Based on Acceleration variations it detects the latitude and longitude axis. It obtains current position according to the latitude and longitude accelerometer readings. In our proposed Senspeed application Additional features compare to existing application are as follows: 1.

Detecting movements of the vehicle, drifting and major advantage is Sending SMS to registered user. To control traffic and provide driver safety and to prevent from aggressive drivers. Senspeed application gives feasibility safety to users. If the aggressive driver ride with over speed then the acceleration will keep on varying. If the acceleration variation is crossed the limit then the SMS is sent to the registered user. SMS includes location, time, Speed limit crossed
In this paper the author consider a sensing approach, which uses Smartphone sensors to sense natural driving conditions, to derive the vehicle speed without requiring any additional hardware. We established by using © 2017, IRJET
