The present study intends to develop a method for analyzing users’ behavior in the service area of expressway by open/close log sensor attached to the toilet booth doors. This method clearly shows the uneven usage of the toilet booth, which may result in inefficient use of the facilities as well as a damage caused by concentration of usage. The reason of the user’s choice behavior was discussed by the layout of toilet booth and the visibility of the interior spaces of the lavatory viewed from the entrance.
