The problem statement chosen was to build a model that makes sure that the rules for the speed limit are followed in every road segment and thus reducing the possibility of accidents and ensures safer automobile systems.
Main motive for designing this model is to avoid accidents and alert the drivers about speed limit for safe travelling in every road segment. Most drivers are tempted to exceed the speed limit at one time or another. Speed has been identified as a key risk factor in road traffic injuries, influencing both the risk of a road crash as well as the severity of the injuries that result from crashes. Controlling vehicle speed can prevent crashes happening and can reduce the impact when they do occur, lessening the severity of injuries sustained by the victims. The relationship between speed and injury severity is particularly critical for vulnerable road users such as pedestrians and cyclists.
Road rash is a common problem that claims a considerable number of lives every year. According to a study conducted in India, about 77% of road accidents in the country are due to the driver not following the traffic rules and regulations. In the proposed model, we consider the speeding problem and rectify it with the help of a combined effect of Global positioning Systems via commercial navigation maps and automatic Speed control of electric vehicles. The location of the automobile is tracked periodically in real-time. This is achieved with the help of the commercially available online navigation maps. We have used the Google Maps here. The data from the navigation maps are intercepted by a microcontroller. We use the 8-bit AVR Microcontroller, Arduino in this presented model, owing to its simplicity in usage. The Arduino accesses the required data from Google Maps by making use of its own Java library. The data thus obtained is used by the Arduino to know the exact location of the vehicle and the speed limit of that place. The speed limit data can be gathered with respect to both roads and road segments. The Arduino is also interfaced with the Motor Driver Controller Module (L298n). The Driver Module controls the speed of the DC Motors in the electric vehicle influenced by the commands from the Arduino. The Arduino sends out the commands to change the speed of the DC Motors based on the speed limit values previously acquired from the Navigation map.
In this way, the suggested model makes sure that the rules for the speed limit are followed in every road segment and thus reducing the possibility of accidents and ensures safer automobile systems.
