摘 要：We present energy-ecient algorithms for three such applications: automatic vehicle classi cation for categorizing each passing vehicle based on its axle count and inter-axle spacings; weigh-in-motion for estimating individual axle weight and total weight of trucks while they are traveling at normal speeds; and estimating pavement displacement from measured acceleration.
