Transportation planning for disasters: an accessibility approach
A methodology is developed in this paper for evaluating and enhancing the performance of urban transportation systems in the aftermath of a disaster. A performance measure is proposed for assessing overall and distributional impacts based on the concept of accessibility. The methodology is demonstrated with two case studies. The first focuses on passenger railroad disruption in the catastrophic...
متن کاملAccessibility Indicators for Transportation Planning Using GIS
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...
متن کاملAccessibility Analyst: an integrated GIS tool for accessibility analysis in urban transportation planning
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, con...
متن کاملGIS 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 کاملUsing Potential Accessibility Measure for Urban Public Transportation Planning: a Case Study of Denizli, Turkey
Policy makers and planners evaluate the implementation of the urban public transport (UPT) planning studies in terms of some objective measures such as load factor, mean volume per trip, capacity usage ratio and total capacity. In some cases, improving these measures may lead an unforeseen decrease on accessibility to the opportunities in terms of UPT users. Thus, this study aims to evaluate Po...
