摘要
Roundabout with signals is a common application in many countries. Although it has an emerging trend, design criteria are still ambiguous. On the other hand, performance of these types of intersections can only be measured by a number of simulation programs. Therefore it is an interesting topic for many researchers. In this study, primarily, signalized roundabouts are discussed and in particular, the relationship between the left-turning traffic volume and the intersection storage area and signal timing system is investigated. The effects of intersection design are evaluated regarding to intersection type and phase plans and performance of design is measured by considering delays of intersections. The results show that, alternative intersection types can be preferred instead of roundabout with signals in case of increased left turns.
