In this paper, we propose a method to summarize an egocentric moving video (a video recorded by a moving wearable camera) for generating a walking route guidance video. To summarize an egocentric video, we analyze it by applying pedestrian crosswalk detection as well as ego-motion classification, and estimate an importance score of each section of the given video. Based on the estimated importa...

OBJECTIVES Motor vehicle-pedestrian crash is a significant public health concern. The urban campus of Georgia State University poses unique challenges due to a large number of students and university employees. The objectives of this study are twofold: 1) to examine the correlation between specific features of the built environment on and around the University campus and pedestrian crashes; and...

OBJECTIVE Thousands of American children are injured or killed each year as pedestrians, but behavioral factors in pedestrian injury etiology remain poorly understood. We examined the roles of children's individual differences (age, gender, and inhibitory control) and parental supervision in children's pedestrian behaviors. METHODS Using the pretend road method, a sample of 85 children and 26...

In the last decade, pedestrian fatalities at night, especially midblock locations, have been increasing an alarming rate. Lighting is effective countermeasure in reducing nighttime crashes. However, few studies evaluated effects of crosswalk lighting on visibility locations. There existing need to develop designs that increase visibility. Further, safety never directly compared other pedestrian...

Urban intersections are the most dangerous parts of a blind or visually impaired person's travel. To address this problem, this paper describes the novel "Crosswatch" system, which uses computer vision to provide information about the location and orientation of crosswalks to a blind or visually impaired pedestrian holding a camera cell phone. A prototype of the system runs on an off-the-shelf ...

Increasingly, cities worldwide are striving for green travel and slow traffic, vigorously developing people-oriented urban pedestrian traffic with sustainability has become a fixture in recent discourse. This paper comprehensively considers the sidewalk’s facilities environment status of flow; divides road system (UPRS) into five subsystems around underpass, overpass, crosswalk, sidewalk, cross...

Urban intersections are the most dangerous parts of a blind person’s travel. Proper alignment is necessary to enter the crosswalk in the right direction and avoid the danger of straying outside the crosswalk. Computer vision is a natural tool for providing such alignment information. However, little work has been done on algorithms for finding crosswalks for the blind, and most of it focuses on...
