Space-time and integral measures of individual accessibility: a comparative analysis using a point-based framework
TLDR
In this paper, the authors compare the relationship and spatial patterns of these thirty accessibility measures using network-based GIS procedures and conclude that space-time and integral indices are distinctive types of accessibility measures which reflect different dimensions of the accessibility experience of individuals.Abstract:
Conventional integral measures of accessibility, although valuable as indicators of place accessibility, have several limitations when used to evaluate individual accessibility. Two alternatives for overcoming some of the difficulties involved are explored in this study. One is to adapt these measures for evaluating individual accessibility using a disaggregate, nonzonal approach. The other is to develop different types of measures based on an alternative conceptual framework. To pursue the former alternative, this study specifies and examines eighteen gravity-type and cumulative-opportunity accessibility measures using a point-based spatial framework. For the latter option, twelve space-time accessibility measures are developed based on the construct of a prism-constrained feasible opportunity set. This paper compares the relationships and spatial patterns of these thirty measures using network-based GIS procedures. Travel diary data collected in Columbus, Ohio, and a digital data set of 10,727 selected land parcels are used for all computation. Results of this study indicate that space-time and integral indices are distinctive types of accessibility measures which reflect different dimensions of the accessibility experience of individuals. Since space-time measures are more capable of capturing interpersonal differences, especially the effect of space-time constraints, they are more “gender sensitive” and helpful for unraveling gender/ethnic differences in accessibility. An important methodological implication is that whether accessibility is observed to be important or different between individuals depends heavily on whether the measure used is capable of revealing the kind of differences the analyst intends to observe.read more

The role of transit accessibility in influencing the activity space and non-work activity participation of different income groups
TL;DR: In this paper , the authors investigated the role of transit accessibility on the activity space of three income groups in Hong Kong and found that the availability of transit stations and network accessibility by mass transit rail (MTR) are significantly linked to the spatial extensiveness of activity spaces of higher and medium-income commuters, while bus plays a more important role for the daily mobility of the low-income group.

Geospatial Analysis and Application: A Comprehensive View of Planning Support Issues in the Beijing Metropolitan Area
Ying Long,Zhenjiang Shen +1 more
TL;DR: In this paper, urban activity refers to human behaviour taking place in urban space, and their spatial pattern can reflect how human beings behave relative to the urban form, and the analysis was intended to identify the conflicts between urban activity and urban spaces, therefore providing solutions to the planning and design issues.
