Pradhan, Dibyaranjan and Behera, Ramakant (2011) Modeling of a vehicle speed measurement system using piezoelectric sensors. BTech thesis.
With increasing number of population and higher rate of development the problem of road accident is also increasing rapidly. So the basic concept is to develop a model that can be useful as a security system in the society and can control vehicle speed.
The property of piezoelectric effect can be used to design a model that can be put on the road surface and whenever a vehicle with higher velocity crosses the sensor it will generate a alarming condition. Two rows or arrays of piezoelectric crystals will be put on the road surface at a fixed distance. Whenever a vehicle passes over the surface of 1st array of sensor it will give a voltage output that can be useful to start the timer in microcontroller and while the vehicle will pass over the second array of sensor, the voltage output from it will deactivate the timer in the microcontroller. Hence the total time taken by vehicle can be determine and so as velocity of vehicle as we know the fixed distance between the two arrays of sensor.
