Abstract:Safety concern is one of the core issues that deter people from bicycling in the US. Earlier studies have explored the associations between intersection design characteristics and bicyclist safety perceptions. Research shows that there are significant links between bicycling choice, safety perceptions, bicycling experience levels and socio-demographics. Yet, the existing bicycling safety-rating models do not control for the individuals' socio-demographics and bicycling experiences that are known to affect bicycling choice. This study develops a Perceived Bicycling Intersection Safety (PBIS) model which helps engineers, planners and decision-makers better understand the contributions of a wide range of intersection features to bicyclists safety perceptions, controlling for socio-demographics and bicycling experiences. The empirical analysis is based on an online visual survey conducted at the main campus of The Ohio State University through March and April 2017. We determine that visual surveys are effective in capturing information about bicycling preferences. We conclude with recommendations for infrastructure decisions and suggestions for future research. The results of this study can help planners design street intersections that bicyclists prefer. Our model can be applied elsewhere to test the effects of different intersection and street features.
