We present a vehicle counting system using a road-side microphone array. Our system uses two microphones on one side of the road to count vehicles coming from two directions, which drastically reduces the installation cost. Based on a previous work, we generate a "sound map", which is a time-difference map of vehicle sound on the two microphones. Prior to count vehicles, we apply a simple image processing technique on the sound map to minimize the effect of noise. We describe the design and implementation of our vehicle counting system. Experimental evaluation reveals that our system successfully counted vehicles with an F-measure of 0.92. |
