摘要

Unlike other types of controlled intersections, drivers do not always comply with the “yield to pedestrian”sign at the roundabouts. This paper aims to identify the contributing factors affecting the likelihood ofdriver yielding to pedestrians at two-lane roundabouts. It further models the likelihood of driver yieldingbased on these factors using logistic regression. The models have been applied to 1150 controlledpedestrian crossings at entry and exit legs of two-lane approaches of six roundabouts across the country.The logistic regression models developed support prior research that the likelihood of driver yielding at theentry leg of roundabouts is higher than at the exit. Drivers tend to yield to pedestrians carrying a white canemore often than to sighted pedestrians. Drivers traveling in the far lane, relative to pedestrian location, havea lower probability of yielding to a pedestrian. As the speed increases the probability of driver yieldingdecreases. At the exit leg of the roundabout, drivers turning right from the adjacent lane have a lowerpropensity of yielding than drivers coming from other directions. The findings of this paper further suggestthat although there has been much debate on pedestrian right-of-way laws and distinction betweenpedestrian waiting positions (in the street versus at the curb), this factor does not have a significant impacton driver yielding rate.The logistic regression models also quantify the effect of each of these factors on propensity of driveryielding. The models include variables which are specific to each study location and explain the impact sizeof each study location on probability of yielding. The models generated in this research will be useful totransportation professionals and researchers interested in understanding the factors that impact driveryielding at modern roundabouts. The results of the research can be used to isolate factors that may increaseyielding (such as lower roundabout approach speeds), and can feasibly be incorporated intomicrosimulation algorithms to model driver yielding at roundabouts.
