People with disabilities face many obstacles in everyday outdoor travels. One of the most notable obstacles is steep slope on sidewalk segments. Current navigation systems/services do not all support map databases with slope attributes and cannot calculate sidewalk slope in real time. In this paper, we present a technique for calculating slopes of sidewalk segments by image data and predict the...

This article examines the different failure modes of concrete sidewalks through an extensive field survey of sidewalk inventories in major cities in the Canadian Prairies. The major form of sidewalk damage is longitudinal cracks. There was no correlation of either the liquid limit or the plastic limit of the soil beneath the sidewalk with the type of sidewalk damage observed in each city. Howev...

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 =...

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...

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...

The quality of OpenStreetMap (OSM) data has always been of main concern for use in different projects. In our study, in order to understand the fitness for use of OSM data for a routing and navigation system for people with limited mobility, we have assessed the completeness of OSM data with regards to sidewalk information. Relevant attributes for sidewalk information have been considered, and ...

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 ...
