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.
