Outline of Final Research Achievements

Alternative Intersections (AIs) has a potential be a promising solution to improve safety and the smoothness of overcrowded at-grade intersections. This study investigated AIs in the US and other countries by literature review, field survey and interview survey, and evaluated its characteristics and performance. Then, traffic simulation analysis was conducted to evaluate the performance of AIs assuming them to be introduced to Japanese intersections. Also, driving simulator experiment was conducted to evaluate drivers' acceptability in driving at AIs. Based on these analyses, advantages and applicability of AIs to Japanese road environment were clarified.
