PROJECT DESCRIPTION

The main aim of this project is to implement a rash-driving-detection system on highways that alerts traffic control authorities wirelessly in case of speed violation by any vehicle. Nowadays, accidents are taking place frequently on the highways due to over speeding by vehicles resulting in many casualties.

In the current systems, to detect rash driving, policemen use a handheld radar gun to record vehicle speed. If any vehicle exceeds the speedlimits, then the information of that vehicle goes to the nearest police station for necessary action. This is an ineffective process, and hence there is  a need to develop a device that detects rash driving based on certain time limit means of sensing.

The proposed system fulfills that requirement as it consists of two blocks:transmitter and receiver; both use a microcontroller of the 8051 family and a rectified-power supply. This project consists of an RF transceiver module operating at 2.4 GHz.

Rash driving is detected by the IR sensor interfaced to the microcontroller at the transmitting end. A 16*2 LCD display is connected to the microcontroller for displaying the information.  A buzzer is interfaced to the microcontroller for giving an alert to the user. A lamp is controlled by the relay, which is connected to the microcontroller for indication purpose.

Predetermined time limit is set with sensors at two different points with certain distance between them for a vehicle to cross these points. If the vehicle crosses this distance in less than the predetermined fixed time limit, then the buzzer  and lamp gives an alert to the traffic authorities at both the locations, wirelessly. The time taken by the vehicle to travel from one set point to the other is calculated by the microcontroller's program and the information is  displayed on the LCD display.

This project in future can be extended by integrating a camera with the system which could capture the image of the number plate of the vehicle and send it to the traffic authorities.

Q & A
Q:  What is the formula for calculating smoothing capacitor value?
A:  There is some approximated formula .Peak to peak ripple voltage = Load current in amps / (2*line frequency in hertz *capacitance in farads). But as rule of thumb for 1 A current 1000uF is best. Thus it is load dependent.
Q:  What to do when the lamp fails and what is the maximum lamp rating that can be used?
A:  If the lamp fails one can use any lamp or bulb which is used in homes up to 100W. We suggest you to go for low watt bulbs
