Bicycle route and safety datasets for 2963 commuter cyclists in Ottawa and Toronto, Canada containing cyclist characteristics, collision and fall history, and regular commute route, are used for this analysis. Previous analyses found sidewalk collisions, fall and injury rates significantly higher on sidewalks versus roads or paths. Of the 52 events reported on sidewalks none were reported to po...

The article presents a proposal of a model of fatigue destruction of hydrophobised ceramic brick, i.e., a basic masonry material. The brick surface was hydrophobised with two inorganic polymers: a nanopolymer preparation based on dialkyl siloxanes (series 1-5) and an aqueous silicon solution (series 6-10). Nanosilica was added to the polymers to enhance the stability of the film formed on the b...

BACKGROUND Walking in neighborhood environments is undertaken for different purposes including for transportation and leisure. We examined whether sidewalk availability was associated with participation in, and minutes of neighborhood-based walking for transportation (NWT) and recreation (NWR) after controlling for neighborhood self-selection. METHOD Baseline survey data from respondents (n =...

This paper presents a sidewalk pavement width design method for making more pedestrian friendly and walk-inspiring sidewalk pavements in the urban area. Instead of using the current sidewalk pavement width design standard that usually leads to having minimum values, this research investigated pedestrians’ preferences on the levels of service, surveyed actual foot path trajectories in the sidewa...

Broken sidewalks have become an important legal issue since 2002 when the United States Court of Appeals for the Ninth Circuit ruled that the Americans with Disabilities Act ADA applies to sidewalks. As one way to comply with the ADA, cities can require property owners to repair any broken sidewalk fronting their property before they sell the property. Before any real estate is sold, the city i...

This study investigated the effects of rehabilitation of sidewalks on improvement of the pedestrians’ mobility. In order to successfully achieve this, sidewalk characteristics were determined via previous studies, expert elicitation and field studies and seven parameters which are available in Tehran’s sidewalks were chosen. These seven parameters were “Side trees of sidewalks”, “Width of sidew...

This study was to search for the desirable direction of the sidewalk planning in Korea by establishing the concepts of walking and pedestrian space, and analyzing the advanced precedents in and out of country. Also, based on the precedent studies and relevant laws, regulations, and systems, it aimed for the following sequential process: firstly, to derive design elements from the functions and ...

among the low–dimensional allotropes of carbon, nanotubes and graphene have attracted very much attention from nano–science and nanotechnology specialists. they have been proposed as building blocks in nanometer device engineering. however, these structures are not defect–free. in this thesis, we focused on defective carbon nanotubes and graphene, and studied the effect of couple of very common...
