We develop the article in four parts, following the introduction found in section one the article touches on three elements of law and public policy. The second section consi...

Walking is being promoted for health and transportation purposes across all climatic regions in the US and beyond. Despite this, an uncomfortable microclimate condition along sidewalks is one of the major deterrents of walking, and more empirical research is needed to determine the risks of heat exposure to pedestrians while walking. This study examined the effect of street trees and grass alon...

Managing road assets, such as roadside curbs, is one of the interests of municipalities. As an interesting application of computer vision, this paper proposes a system for automated measurement of the height of the roadside curbs. The developed system uses the spatial information available in the disparity image obtained from a stereo setup. Data about the geometry of the scene is extracted in ...

This paper describes seMole (semantic Mole), a robust framework for harvesting information from the World Wide Web. Unlike commercially available harvesting programs that use absolute addressing, seMole uses a semantic addressing scheme to gather information from HTML pages. Instead of relying on the HTML structure to locate data, semantic addressing relies on the relative position of key/value...

ABSTRACT In this paper, we propose a method for estimating the number of pedestrians walking in opposite directions, as in cases of a shopping street or a sidewalk in a downtown area. The proposed method utilizes a compound-eye sensor that is constructed by placing two binary sensors for the pedestrians' movement direction and multiple binary sensors for the vertical direction of the pedestrian...

Anna did not simply decide one day that people were made of paper. She came to the conclusion slowly and reluctantly, several months after she ! rst noticed that the consistency of everything around her had subtly changed. Books and chairs and buildings were no longer solid but composed of tiny, buzzing particles. She thought if she blew on a lamppost it should disperse into air. On her way to ...
