Factors associated with compliance rate at pedestrian crosswalks with Rectangular Rapid Flashing Beacon

In the recent decade, Rectangular Rapid Flashing Beacon (RRFB) has been introduced and widely installed across North America to improve pedestrians' safety at crosswalks. While the treatment has been reported to be effective in improving safety, relatively few studies have been conducted to explore the factors associated with its effectiveness. This study investigates the effect of road characteristics, environmental factors, and device specification on vehicles' yielding compliance, used as a surrogate measure of safety. Nineteen crosswalks within the City of Calgary were chosen for field study. An ordinary least squares regression model is applied to identify the factors that affect the compliance rate. It is found that type of road, daily traffic volume, posted speed limit, median, and rainy weather have significant impacts on the compliance rate. Besides, the result suggests using smaller size beacons and installing them above the pedestrian sign to improve safety to its fullest at RRFB-enhanced crosswalks
