Tiivistelmä
Using noise sensor networks is one of the applications to monitor road traffic. Normally the equipments which are used to measure are much expensive. The purpose of this project was to use the low-cost wireless sensor networks to moni-tor the vehicle‟s speed and calibrate the accuracy of the result.
Actually we set two wireless sensors which are separated by a specific distance beside the highway and we collect the data of the vehicle passing this road during the specific time. Then we calculate the time difference of the vehicle passing these two sensors. At the end using distance divides time difference we can know the vehicle‟s speed.
From the calibration we can know the result is accurate but there is a little bit er-ror. So the algorithm can still be improved to provide a more accurate result in the future.
