A road traffic census is an investigation to understand the realities of the road traffic in Japan, and there are the general traffic density investigation and the parking investigation. Especially, the general traffic density investigation measures the traffic of the pedestrian, the bicycle, and the car every one hour on the weekday or holiday. Therefore, grasping local environment and local traffic density can be estimated the traffic for the future by executing road traffic census. Recently, with a development of information technology, the traffic density investigation can automatically be measured using the animation filmed with the video camera. In an existing research, a general and highly accurate method of detecting people is not established. Then, in this research, we try to establish it. Firstly, the area of people is specified by the background difference method and the smoothing process. Secondly, the feature of people is extracted by the labeling. Finally, the movement of people is measured from the area lap rate of the labeling. This research is applied to the crowded space like the elevator, and we aim for the development of a general and highly accurate system for measuring the flow of people.
