Description

<p>There are many cases where Diverging Diamond Interchange (DDI) is adopted to prevent traffic accidents relevant to right-turning vehicles at the conventional diamond interchange in Western countries. This paper aims to evaluate the safety of vehicles and pedestrians at DDI based on subject experiments for Japanese drivers and pedestrians by means of a driving simulator and head mount display after virtually reproducing the intersection model in the 3D virtual reality space with reference to the existing intersection shape in Japan. With respect to the driving experiment, compared to the conventional diamond interchange, it is found that DDI has a deceleration effect on vehicles and tends to induce the drivers’ yielding behavior to pedestrians. Additionally, from the perspective of pedestrians, it is revealed that DDI has a superiority in ease of safety confirmation when crossing via analysis of pedestrians’ head motion. Also, the model analysis using the ordered logit model and structural equation model indicates that rearrangement of sidewalk design will lead to creating positive awareness of pedestrians.</p>
