  • When an automatic tra±c light system is
    not working e.g. due to tra±c jam, it is necessary for traf-
    ¯c police to control the tra±c by gestures. In this paper,
    the design of a system to synchronize tra±c lights with
    tra±c police gestures is presented. The gesture data are
    extracted by ¯xing a 3-axis accelerometer on the back of
    each hand. Signals obtained from the accelerometers are
    transformed into arm motion and palm orientation. A hi-
    erarchical classi¯er is designed to recognize the gestures, in
    which fuzzy rules are used to enable vague gesture recog-
    nition. An embedded micro-processor system has been de-
    veloped for real-time gesture recognition. Wireless mod-
    ules are used for communication and a digital compass is
    used to identify the direction, to which a tra±c policeman
    faces. The integrate system has been tested, and the fea-
    sibility of the system to synchronize tra±c lights has been
    demonstrated.
