The steady increase of traffic demand over the past decades has led to a high rate of congestion and traffic accidents on many parts of road networks. It is essential to solve traffic congestion and traffic accidents. Variable speed limit control is an effective method to relieve traffic congestion, improve traffic safety and steady traffic flow. In this(More)
In recent years, orthogonal frequency division multiplexing (OFDM) technology has been widely investigated for both point-to-point underwater acoustic communications and for networks. In this paper, we implement the OFDM underwater acoustic communication algorithm on an OMAP-L138 platform, which possesses characteristics of low-power, rich peripheral and(More)
Recently, traffic accident detection is becoming one of the interesting fields due to its tremendous application potential in Intelligent Transportation Systems. In this paper, we present a vision-based real time traffic accident detection method. We intend to extract foreground and background from video shots using the Gaussian Mixture Model (GMM) to(More)
