| Outline of Final Research Achievements |
This study aims at developing a methodology for entry capacity estimation of roundabouts in Japan considering conflicts between pedestrians and vehicles. 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.
