Conventional transportation planning is often focused on improving movement (or mobility)—most often by the automobile. To the extent that accessibility, a well-known concept in the transportation planning field since the 1950s, has been measured or used in transportation planning, such measures have also been auto-based. Broadening the scope of accessibility to include a wide array of destinat...

The concept of accessibility needs to take into account factors like individual needs, preferences, and abilities as well as transportation, land use, and finances. This article proposes a sensitive space–time accessibility indicator from a regional perspective. This indicator, representing cumulative available activity time with a regional context, is different from both traditional accessibil...

BACKGROUND The accessibility to health centers is a limitation to the use of preventive and curative health centers. AIM To assess geographic accessibility using a parameter that integrates information about the use of preventive services and travelling time from home to the health center. MATERIAL AND METHODS We analyzed target geographical areas of 10 community centers located at the Nort...

Accessibility is both an important concept, and a powerful indicator, in the understanding of the impact of spatial technologies, i.e. transportation, communication, and information technologies. However, virtually all existing measures of intra-metropolitan accessibility incorporate only transportation without considering other means of spatial interaction. In this paper, the author argues tha...

Food deserts-areas with a significant low-income population experiencing low accessibility to healthy food sources-have been well studied in terms of their connection to obesity and its related health outcomes. Measuring food accessibility is the key component in food desert research. However, previous studies often measured food accessibility based on large geographic units (e.g. census tract,...

Accessibility is commonly assessed using indicators calculated from spatial data. Comparatively perceived accessibility cannot be adequately reflected by these measures because it involves the perception to participate in spatially dispersed opportunities. This highlights need understand and consider for planning evaluation of transport systems a complementary perspective. Therefore, this study...

In these days, remotely sensed imagery has been widely used for GIS-T (Geographic Information Systems for Transportation). As for this approach, topological measure and spatial metrics of transportation network structure such as road layer can be considered as one of important factors in urban transportation analysis. Related to this measure, it is known that the connectivity such as alpha inde...

In this paper a method to create GIS-based accessibility indicators is presented. The method allows to create person-by-person and store-by-store (disaggregate) accessibility indicators but also to derive zonal summary (aggregate) indicators that can be used in more traditional transportation planning applications. These indicators have also been used as explanatory variables in person-based tr...

This study uses accessibility as a performance measure to evaluate a matrix of future land use and network scenarios for planning purposes. The concept of accessibility dates to the 1950s, but this type of application to transportation planning is new. Previous research has established the coevolution of transportation and land use, demonstrated the dependence of accessibility on both, and made...
