FIELD OF INVENTION:
The present subject matter relates to a field of Electrical and Electronics Engineering and particularly related to A Predictive Accident Prevention System for Vehicles Safety on Sharp Turns on Hilly Roads is focused on to decrease the probability of road accidents on sharp or blind turns which are quite often on hill areas. It helps to vehicle to avoid the sharp blind turn situations to protect from collisions with other down or upcoming vehicles. This invention focuses on prior intimation of any obstacle on blind turns to reduce the risk of accidents.

BACKGROUND AND PRIOR ART:
[001] This invention is based on core processing unit as Arduino and sensors systems to process the obstacle information with the help of adequate programming and signal processing.
[002] The invention is oriented as per the poor historical records of large number of the accidents and prevention of collisions is the most crucial issues. As per nowadays not preventive measures are practically proposed by the transport organizations. Conventional measure includes improvement of geometric design, congestion control management and somehow driving training and enforcement. Limited outcomes are perceived and actual control on accident measures are too low. This realization along with the increasing need to reduce crashes and their side effects has recently led to proactive approaches in order to avoid their occurrence in the first place. One of the most promising options gaining wide acceptance in recent years is the concept of detecting crash-prone flow conditions in real-time and warning drivers when the probability of a crash is high in order to increase their attentiveness, thereby reducing the number of crashes.
[003] Evidence suggests that when driver attentiveness increases, crashes decline despite of poor driving and environmental conditions. However, research in identification and detection of crash prone traffic conditions is embryonic. Enough proof that such conditions exist is still lacking, let alone a methodology for effective detection and system deployment. Based on the available literature, research on the subject can be divided into two major areas. The first covers studies aimed at developing models for the estimation of safety metrics, such as crash rate and severity. This is accomplished by associating such metrics with traffic, roadway, and driver/vehicle characteristics. The second area of research covers studies aimed at developing models for real-time estimation of crash likelihood. Potentially the latter can be used in real-time driver warning systems.
[004] United State patent number US6405132B1 relates to system and method for preventing vehicle accidents in which GPS ranging signals relating to a host vehicle's position on a roadway on a surface of the earth are received on a first communication link from a network of satellites and DGPS auxiliary range correction signals for correcting propagation delay errors in the GPS ranging signals are received on a second communication link from a station or satellite. The host vehicle's position on a roadway on a surface of the earth is determined from the GPS, DGPS, and accurate map database signals with centimeter accuracy and communicated to other vehicles. The host vehicle receives position information from other vehicles and determines whether any other vehicle from which position information is received represents a collision threat to the host vehicle based on the position of the other vehicle relative to the roadway and the host vehicle. If so, a warning or vehicle control signal response to control the host vehicle's motion is generated to prevent a collision with the other vehicle.

[0011] The principal objective of the present invention is to provide accident preventive safety system to the vehicles on hilly areas, specifically on sharp blind turns.

[0015] These and other objects and advantages of the present subject matter will be apparent to a person skilled in the art after consideration of the following detailed description taken into consideration with accompanying drawings in which preferred embodiments of the present subject matter are illustrated.
SUMMARY OF THE INVENTION:
[0016] This Smart Road Safety and Vehicle Accident Prevention System for Mountain roads focuses on the improvement of the current functionality of accident preventive system. The main functioning of system predicts the color changing and buzzer scheme of combinational communication of the sensors during upcoming and down coming vehicles movement. Two cars are coming from the opposite direction on hill roads and then the color of LED changes to red with buzzer sound as an indication of obstacle from other side. This invention proposes a simplistic approach for the implementation of a Collision Avoidance System in hairpin bends on a hilly track, Ghats, or zero visibility turns using IR proximity sensors.
[0017] It uses two IR sensors, which are placed on either side of the hairpin bend. One sensor is installed by the side of the up-hill section of the road, similarly one sensor is installed by the side of the downhill section of the road. The sensors are mutually exclusive and are connected to ATmega328P microcontroller through wires. Based on the output of sensors, position of vehicles on either side of the bend is detected which is provided as an input to the microcontroller. The microcontroller which works on a power supply of 9V runs a Priority algorithm which triggers the warning LEDs to glow (led1 in Downhill or led2 in Uphill) and thereby intelligently controlling the movement of vehicles at the bend.
[0018] The present subject matter relates to development and implementation of crash prevention systems can be divided into two categories. The first category deals with in-vehicle crash avoidance systems like adaptive cruise control, forward and backward collision avoidance systems, run off-road driver assist systems, as well as the larger intelligent vehicle highway system program aimed at removing the driver from the equation. Most of these systems depend on instruments in the vehicle which measure speed, headway, acceleration/deceleration, and distances from the surrounding vehicles and use these to influence the vehicles trajectory and avoid a collision or running off the road. In general, none of these systems depend on information concerning the general traffic flow conditions or even what happens 2-3 vehicles ahead. Although a number of these systems have reached the market, very few vehicles in the road are currently equipped with such systems.
[0019] The foregoing summary is illustrative only and is not intended to be in any way limiting. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features will become apparent by reference to the drawings and the following detailed description.

A person skilled in the art will easily recognize from the following description that alternative embodiments of the structures and methods illustrated herein may be employed without departing from the principles of the disclosure described herein.

DESCRIPTION OF THE PREFERRED EMBODIMENTS:
[0025] While the embodiments of the disclosure are subject to various modifications and alternative forms, specific embodiment thereof have been shown by way of example in the figures and will be described below. It should be understood, however, that it is not intended to limit the disclosure to the forms disclosed, but on the contrary, the disclosure is to cover all modifications, equivalents, and alternative falling within the scope of the disclosure.
[0026] The terms “comprises”, “comprising”, or any other variations thereof used in the disclosure, are intended to cover a non-exclusive inclusion, such that a device, system, assembly that comprises a list of components does not include only those components but may include other components not expressly listed or inherent to such system, or assembly, or device. In other words, one or more elements in a system or device proceeded by “comprises… a” does not, without more constraints, preclude the existence of other elements or additional elements in the system or device.
[0027] The present subject matter relates to some preventions through this invention that is we can stop the vehicles from accidents and unwanted incidents. When, we drive on hill roads the vehicles will automatically get information about the presence of another vehicle and any collision that appears. Driver alert system is the decades old Highway Advisory Radio (HAR) system. Automated driver warning and crash prevention systems based on dynamic weather and pavement information have been deployed in the field during the last ten years. These systems depend on sensor information on rain, fog, and pavement ice formation to trigger warning mechanisms like VMS, variable speed limit signs, entrance ramp gates, and de-icing systems. None of the deployed systems consider the prevailing traffic conditions. In most studies related to the estimation of crash probability, the information comes from historical records.
[0028] These and other advantages of the present subject matter would be described the information about the crash event is based on the available police records, it is not always accurate or complete and this introduces uncertainty and errors into the analysis. Additionally, the detail contained in the records is limited and does not always allow the observer to understand the sequence of events leading to the actual collision. In this invention, a system development is focussed to avoid blind turn accidents, specifically on mountainous roads.
[0029] Reference may be made to Figure 1 illustrating block diagram view of design layout of main controller circuit, in accordance with an embodiment of the present subject matter. The present subject matter relates to microcontroller based main controlling unit with IR sensor transmission and switching modules. The circuit diagram represents the main control unit and connected applications with Arduino MCU. This a unique and cost-effective model to elaborate building and large-scale accident preventive models.
[0030] Reference may be made to Figure 2 illustrating diagrammatic view flow chart of soft-computing scheme of process of prevention and device operations. The model layout consists of open source IDE and computer-based applications, main process unit as MCU, external circuitry sensors & LEDs to connect various real time applications-based appliances.
[0031] Reference may be made to Figure 3 illustrating block diagram view of Arduino based MCU connection to implant on both side of the turns. When all sensors (IR) are connected to MCU responses are recorded on signaling applications when any obstacle come across the sensing domain. This has been experimented and tested for applications applicable for common resources with possible range and height of the obstacles coming from opposite side on the blind turns.
[0032] Arduino based application and some extent Windows Application, but also about all handling procedure related with Smart road safety and vehicle accident prevention system for mountain roads. It also provides knowledge about the latest technology used in developing new technology that will be great demand in future. This will provide better opportunities and guidance in future in developing inventions independently.
[0033] An attempt is made in all its earliest towards the successful completion of the invention. This invention is user friendly since it has been developed in Arduino. The control will be more powerful of this invention. Connecting it to any type of accidents prevention application extends the development control. Upgrading the system if may be able to be done without affecting the proper functioning of system.
[0034] In accordance with advantages of the present subject matter relates to decrease the number of accidents occurring on hilly and curved roads. This is done by keeping an ir sensor in one side of the road before the curve and keeping a LED light after the curve, so that if vehicle comes from one end of the curve sensor senses and LED light glows at the opposite side. By this we can save thousands of lives including animals.
