Evaluating Accessibility in Crowdsourcing GIS
نویسنده
چکیده
A recent development in Geographic Information Systems is the use of crowd-sourcing to acquire and share information that was difficult to collect, organize and update in the past. Taking into consideration that the people entering data into the system might not have geographic training, an important concern is related to accessibility. In this paper we propose an algorithm for evaluating accessibility based on the Web Content Accessibility Guidelines defined by W3C.

متن کاملA GIS-based planning approach to locating urban rail terminals
This paper develops a flexible GIS-based methodology for evaluating the potential locations of terminal park-and-ride facilities along urban rail lines. The methodology differs from political-based approaches and traditional travel demand modeling in its use of an objective measure of accessibility to gage the suitability of a site. The methodology begins by constructing an index of derived dem...
متن کاملEvaluating the Impact of China’s Rail Network Expansions on Local Accessibility: A Market Potential Approach
This paper uses a market potential approach to examine the evolution of the rail transport network of China and its spatial distributional impacts on local accessibility, with a particular focus on high-speed rail improvements. Accessibility is measured by using a “market potential” function that was derived from the general equilibrium model of the economic geography literature, and is empiric...
