Accessibility Analyst: an integrated GIS tool for accessibility analysis in urban transportation planning
نویسندگان
چکیده
The authors present an integrated GIS tool, Accessibility Analyst, for accessibility analysis in urban transportation planning, built as an extension to the desktop GIS software package, ArcView. Accessibility Analyst incorporates a number of accessibility measures, ranging from catchment profile analysis to cumulative-opportunity measures, gravity-type measures, and utility-based measures, contains several travel-impedance measurement tools for estimating the travel distance, time, or cost by multiple travel modes along actual travel routes, and interoperates with GIS data-management and data-integration, spatial-analysis, network-analysis, surface-modelling, and spatial-visualisation functions. Undertaking accessibility analysis with use of Accessibility Analyst allows the user to take full advantage of a GIS to produce spatial distributions of accessibility over a region. It can be applied to a wide range of issues in urban transportation planning, such as for studies on the relationship between transportation and land use, evaluation of transportation network efficiency, transportation infrastructure planning, and for impact assessments relating to transportation policies.

Integrated Approach of Spatial Metrics by Graph-based Road Network on Remotely Sensed Imagery for Urban Transportation Planning
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...

GIS Software for Measuring Space-Time Accessibility in Transportation Planning and Analysis
Transportation systems exist to improve individual accessibility. However, emerging applications of GIS in transportation (GIS-T) and intelligent transportation system (ITS) focus on throughput (the amount of system flow) rather than accessibility. Throughput is related but not equivalent to accessibility. Sensitive transportation planning requires rigorous, realistic and tractable accessibilit...

متن کاملDynamic Spatial Analysis of Urban Travel Survey Data using GIS
GIS-T is already recognized as an important domain for the analysis of urban transportation context. However, for the visualization of planning and modeling situations, some new tasks have to be deployed to illustrate complex phenomena emerging from large-scale regional telephone-interviewed household travel survey data such as those conducted at a 5% sampling in Montreal, every five years (400...
