Abstract:
This paper compares existing accessibility measures and develops and
varies some of
these measures for comprehensive analysis of land-use impact on accessibility
and on
travelling patterns using GIS. The paper is based on a literature survey,
a review of
the geographical information in digital maps and available data on
population and
potential destinations. The focus is on place accessibility, but it
also touches on
individual accessibility. The accessibility measure chosen for the
first case study is a
zone-to-point distance measure, estimated separately for different
types of
opportunities and different road-users. The distances between origins
and destinations
are measured as the shortest network distance and actual driving time.
A customised
ArcView Network Analyst is used. Integral zon-to-zon place accessibility
measures
are chosen for the second case study. The main part of the calculations
will be
conducted in programs suitable for matrix operations and for database
analyses, and
the output will be processed in digital maps for presentation.
