Vehicle Queue Length Measurement Based on a Modified Local Variance and LBP
The real-time traffic parameters are necessary to dynamic traffic light control at intersection due to the serious traffic congestion. In this paper, we describe an approach for the real-time vehicle queue length measurement in a video-based traffic monitoring system. It is built on the property of a modified local variance in video frames, which does not rely on any sort of motion detection. In addition, a shadow removal approach is also presented with a simplified LBP as well as this local variance. Experimental results show that the proposed approach can highly improve the performance of the queue length measurement in real time, and it can be efficiently applied in a variety of traffic scenes.
