The main aim of this project is to construct an advanced vehicle over speed detection system with minimizing the limitations of existing methods. Advanced vehicle over speed detection speed sensing mechanism which automatically changing in speed breaker. A speed sensor is connected to a microcontroller which detects when the critical speed is exceede.
This system will check vehicle’s speed and dynamically introduce a speed breaker if it increases a normal range. Speed breaker’ physically constructed in semi circle type. So when vehicle’s speed is high then speed breaker will be taken position in semi circle surface and when vehical’s speed is normal speed breaker will be taken position in flat surface.
Now a days if we observe the roads passed through the villages may have the high chance of accidents, to avoid those accidents we need to reduce the speed of the vehicle for that one are using speed breakers, but due to this the passengers get the difficulty while travelling on these roads, for that one we are giving smart solution for this problem.
The main aim of the speed breakers was reduce the vehicle speed, if the passenger had reduced his vehicle speed there is no need of the speed breaker. So we will use the sensors to monitor the vehicle speed while passenger was arrived to the speed breaker.
To measure the speed of the vehicle we use the wireless sensors 500 meters from the speed breaker, if passenger will not reduce his vehicle speed, we will use some red lights to indicate there is speed breaker ahead of the road, if the passenger already reduced his vehicle speed, the speed breaker automatically reduced height and almost flat to the road, this vertical movements control by the elevation mechanism, this type of activity will create the smooth travelling on the road.
This project helps in improving traffic system, avoid accidents and limit the ehicle at a safe limit.
In this type of system is does not affect the lower speed vehicle(less than permissible speed ) and gives shockless driving.
The sad story about this project is that it also effect the emergency vehicle to reach out at emergency place when it require and it decrease the speed of vehicle.
In this project maximum 2 or 3 vehicle pass through speed breaker at a single time, when more vehicle pass through it cause problem for to measure accurate speed.
Props/Possible solution :At a single time maximum 2 or 3 vehicle can pass through the breaker.>
In a 2 lane roads we can construct both side implement.
Purpose :To avoiding accidents
To safe driving
Product features: Vehicle speed detection and maintain
Arduino unoArduino Uno is a microcontroller board based on the ATmega328 (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started.
The Arduino boards are able to read inputs – light, proximity or air quality on a sensor, or an SMS or Twitter message – and turn it into an output – activating a motor, turning on a light, publishing content online or trigger external events. You can tell your board what to do by writing code and uploading it to the microcontroller on it using the Arduino programming language (based on Wiring), and the Arduino Software (IDE), based on Processing.
The Arduino Uno can be powered via the USB connection or with an external power supply. The power source is selected automatically.
External (non-USB) power can come either from an AC-to-DC adapter (wall-wart) or battery. The adapter can be connected by plugging a 2.1mm center-positive plug into the board’s power jack. Leads from a battery can be inserted in the Gnd and Vin pin headers of the POWER connector.
The board can operate on an external supply of 6 to 20 volts. If supplied with less than 7V, however, the 5V pin may supply less than five volts and the board may be unstable. If using more than 12V, the voltage regulator may overheat and damage the board. The recommended range is 7 to 12 volts.
Serial: 0 (RX) and 1 (TX). Used to receive (RX) and transmit (TX) TTL serial data. These pins are connected to the corresponding pins of the ATmega8U2 USB-to-TTL Serial chip.
External Interrupts: 2 and 3. These pins can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value. See the HYPERLINK ” attachInterrupt() function for details.
PWM: 3, 5, 6, 9, 10, and 11. Provide 8-bit PWM output with the HYPERLINK ” analogWrite() function.
SPI: 10 (SS), 11 (MOSI), 12 (MISO), 13 (SCK). These pins support SPI communication using the SPI library.
LED: 13. There is a built-in LED connected to digital pin 13. When the pin is HIGH value, the LED is on, when the pin is LOW, it’s off.
Ir obstacal sensor
Infrared Obstacle Sensor Module has builtin IR transmitter and IR receiver that sends out IR energy and looks for reflected IR energy to detect presence of any obstacle in front of the sensor module. The module has on board potentiometer that lets user adjust detection range. The sensor has very good and stable response even in ambient light or in complete darkness.
we follow the proposed method, it will reduce the average waiting time in small and medium population cities, and we can say it require very less equipment and no need of the skill labour, based on these considerations we can say for moderate population cities it will be one good method to control the traffic lights at the junctions. Intelligent speed breaker control system also one good idea to give smooth travelling for the passengers.
