An integrated acceleration sensor for traffic condition detection

An acceleration sensor used to determine the vehicles speeds on the highways is developed. The sensor is able to measure the vibrational accelerations perpendicular (out-of-plane) to the asphalt surface as low as 1 mG. The sensor structure is validated with the engineering software packages: ANSYS, COVENTOR and Matlab.
