摘要：	The existing methodology for roundabout entry capacity estimation is assuming the standard geometric layout and user behavior in other countries. However in Japan, it is often likely that the physical splitter islands are not implemented mainly due to space limitations, and thus pedestrian behavior and its impacts on entry capacity are different from those in the other countries. In this paper, simulation analyses were carried out with respect to impacts of geometry and user behavior conditions that are typical in Japan on entry capacity, and by using their results a multiple regression model for entry capacity estimation was developed. The model was validated with data observed at Roppontsuji roundabout in Karuizawa, Nagano. It was found that the estimation performance of the proposed model was very satisfactory while the existing methodology overestimates the capacity.
