Abstract:

The purpose of this paper is to re-evaluate existing findings on crossing behaviors at primary school crosswalks and help develop an optimal signal control policy to reduce vehicle-pedestrian conflicts and improve safety for primary school children and other pedestrians at school crosswalks. Walking is one of the most common modes for school children. Primary school children are always considered the most vulnerable groups in the entire pedestrian population. This paper presents findings of an observational study on primary school children’s walking behavior at crosswalks in the school zones. Based on the analyses result, it showed that guidance was the most significant factor that affect the children crossing speeds. This is true in the sense that children feel more secure when they have accompany when crossing the street. Conversely, boys who walk alone indicated much higher speeds than clearance interval for pedestrians, and would tend to neglect the conflicting traffic with higher walking speed. Therefore, it is suggested to apply split-phase or split leading pedestrian interval (LPI) at school crosswalks instead of simply increasing crossing timing at applicable school intersections and confirm the importance of safety education for students. In addition, the analysis indicated that the 15th 17 percentile and average walking speed of the student whether they walked alone or with guardians were over 3.7 feet (ft)/second (sec) which was higher than New York City Department of Transportation (NYCDOT)’s signal design speed criteria of 3.0 ft/sec.
