Abstract: -Globally road accident is considered to be an important issue, which can be reduced by proper vehicle speed monitoring system. More recently, the advancement in wireless sensor technology shows a great promise in designing Intelligent Transportation System (ITS) due to its flexibility and cost- effectiveness for deployment. The aim of this research is to develop a prototype vehicle speed monitoring system using accelerometer-based wireless sensor. The research focus on unifying the Global Positioning system with embedded wireless fidelity (Wi-Fi) is the new approaches in intelligent vehicle control for critical remote location application using ARM. In conventional system they are designed to control the speed of vehicles in all days. The main objective of the proposed system is to operate the vehicle in safe speed at critical zones.

The functionality of the system has been simulated in laboratory environment bysetting different speed limits for monitoring single or multiple vehicle speed scenarios through appropriate algorithm and code development. The graphical user interface (GUI) of the software continuously presents the vehicle speeds with time and the over speeding conditions are indicated. The speed details are also continuously updated on the left hand side of the GUI. The speeding sensor detects the veichle details and send the data to analysis station and warning messages are sent to the vehicle on other hand veichleAd-Hoc network (VANET) system link nearby vehicles through wireless network The system is also capable of generating an automatic electronic report for a simulated speeding vehicle with vehicle number, speed details, time etc.

Therefore, based on the performance of prototype system, it can be concluded that sensor-based vehicle speed monitoring system has great potential for monitoring vehicle speed wirelessly. Speed Manage software should help to effectively, automatically and intelligently monitor vehicle speed. This paper we implemented with the support of embedded processor and the simulation is achieved through Kiel C.

I. INTRODUCTION

Human errors, in particular driver errors, are the causes for the most of the road accidents. It is reported that over 80% of all major crashes on Irish roads are caused from inconsiderate driving.. However, in most of thecountries speeding or excessive vehicle speed on the road is considered to be the single biggest factor for

road accidents contributing to fatal injuries or even death and financial costs to society

Fig: 1.1. A General framework of vehicle speed monitoring

Nowadays r o a d f a c i l i t i e s are a major concern in the developed world. Recent studies show that one third of the number of fatal or serious accidents are associated with excessive or inappropriate speed, as well as changes in the roadway (like the presence of road- work or unexpected obstacles). The main causes of accidents are vehicle over-speeding, driving after consuming alcohol, distraction during driving, non- adherence to traffic signals, non-wearing of seat-belts and safety gears, tailgating, poor lane discipline etc.

Reduction of the number of accidents and mitigation of their consequences are a big concern for traffic authorities, the automotive industry and transport research groups accidents, etc.), which would need the use of dynamically generated digital maps. The aim of this research is to maintain the speed control over restricted area like (schools, hospitals, colleges etc.,) by using GPS technology. Which was shown in fig 1

II. BACKGROUND OF THIS PROPOSAL

Figure 2.1 shows an example of ITS System used in the UK highway. However, the road accidents are still forecasted as the Headline news in the public media.

Furthermore, the government and various funding agencies are trying to control the road traffic system by spending a huge amount of money. The road transport authority and researchers are working diversely to control the vehicle speed both in urban and rural area

III. PROPOSED HARDWARE SYSTEM

Fig.3.1 Block Diagram For Proposed System

The proposed hardware system portrays that the signals can be monitoring continuously with the help of GPS, if there is normal state, speed is normal. Otherwise the signals can send to an ARM Processor to reduce the vehicle speed. The base station (transmitter) transmits the RF signals by Frequency Modulator connected with Real Time Clock (RTC). The ARM processor is programmed in such a way when the peak hours (Critical time) is exits it transmits the critical frequency.

In the receiver side another ARM processor is to collect the data from GPS and send the signal to device driver to operate the vehicle in safe speed. In this vehicle section LCD Modules displays the activation of critical zone.

While using frequency modulator fix at particular frequency in a transmitter side, whenever vehicle moving on a critical area automatically check and matching the frequency range. If frequency range is critical range will be reduced or else vehicle running at normal speed.

IV. INTELLIGENT TRANSPORTATION SYSTEM

The concept Intelligent Transportation System (ITS) is to improve safety, efficiency and service, and traffic situation by applying advanced technologies of sensing, detecting, computing, communicating, controlling and managing in all kinds of transportations. Traffic information collection is one of the vital parts of intelligent transportation system (ITS) associated with road design, traffic design, traffic management, control, and implementation. General traffic information collection system is based on Inductive loop detector, microwave detection, video detection, infrared detection etc. Dynamic Route Guidance System (DRGS) is one of the important parts of ITS that can supply real-time traffic information and vehicle parameters. Traffic Message Centre (TMC) and on board information receiver are the main elements of DRGS . In the context of this research work, the discussion will be focused on the road traffic monitoring systems with particular emphasis on the wireless systems.

VI. TEST WITH TOY CAR

After attaching the shimmer sensor with the toy car, a wireless connection is established between the sensor and the laptop. The toy car was moved with the remote controller and vibration acceleration data was generated due to vibration from the toy car movement. A wireless connection is established between the sensor and the laptop via Bluetooth. Figure 6. Demonstrates the transfer of data from the sensor to the laptop presents in a graphical format with respect to the elapsed time.

Furthermore, the data is automatically saved in the laptop However; this set-up could not be used for random speed data generation from the relationship between vibration and speed of the toy car. Firstly, the toy car movement could not be controlled on a straight path. Furthermore, the toy car speed could not be varied randomly or maintained at known speed. Therefore, no relationship could be established between the car speed and accelerometer output data.

VII. CONCLUSION

The proposed system mainly designed in order to avoid accidents and to alert the drivers about the speed limits for safe traveling. An effective solution is provided to develop the intelligent vehicle which will operates on safest speed at critical zones and monitor various parameters of vehicle in-between constant time period and will send this data to the base unit is explained in this paper. Controlling the vehicle speed automatically in real time is very difficult. So, in order to avoid those difficulties, instead of controlling the vehicle speed automatically, this research paper succeeded in alerting the driver about the speed limits and detecting the critical area. The entire system is control and the advantage of small volume and high reliability.

Future scope of that is to control the accidents and positioning the accidental vehicle. Many existing systems has discussed about the road safety’s and has proposed many methods for the speed limitations and detection the critical area. The result is simulated and achieved by Keil C software.

SUGGESTIONS FOR FUTURE SCOPE:

The following work can be carried out as a follow up of the current work.

1. For practical applications, the sensor can be attached with the wheel of a vehicle to get the wheel vibration, which can be used for measuring vehicle speed.

2. Multiple sensors can be placed beside the road to measure the vehicle speed between theappearances of the two peaks can be calculated. Thus speed can be determined by the dividing the distance between two sensors with the calculated time.

3. A GPS system can be added to determine the particular speed violation location of vehicles as a feature of identical proofs of the offenders.
