Introduction: The aim of this study was to estimate the associations between neighbourhood built environment characteristics and transportation walking (TW), recreational walking (RW), and moderate-intensity (MPA) and vigorous-intensity physical activity (VPA) in adults independent of sociodemographic characteristics and residential self-selection (i.e. the reasons related to physical activity ...

A reliable, punctual, and spatially accurate dataset of sidewalks is vital for identifying where improvements can be made upon urban environment to enhance multi-modal accessibility, social cohesion, residents' physical activity. This paper develops a synthetically new spatial procedure extract the sidewalk by integrating detected results from aerial street view imagery. We first train neural n...

In our previous research, we examined whether minimally trained crowd workers could find, categorize, and assess sidewalk accessibility problems using Google Street View (GSV) images. This poster paper presents a first step towards combining automated methods (e.g., machine visionbased curb ramp detectors) in concert with human computation to improve the overall scalability of our approach.

Another larger structure which is somewhat unusual is a 54-foot oolitic limestone arch bridge, carrying a stabilized gravel road 22 feet wide with a five-foot sidewalk on one side. This bridge spans McCormick's Creek a few hundred feet above the falls and carries the picnic ground road from the hotel to the Beech Grove area. This structure was built by the CCC camp which was located there for a...
