“…The quantity $Ad#) is the measure of the accessibility of libraryj to the population in census tract i. It is the factor determining the interaction of census tract i with library j and the proportion of the total library circulation from census tract i that goes to library j (Ottensmann, 1980). Thus, for any census tract i, the total accessibility to the library services provided by all the libraries will be the sum overj, giving…”

Equity in the delivery of urban services traditionally has been evaluated by considering the quantities of the service provided to residents of different neighborhoods within the city. For services provided at specific locations, such as branch libraries, such an approach fails to incorporate the importance of travel to the facilities and the value placed on accessibility to them. This study examines service provision by 21 branch libraries in Indianapolis using input and output measures. The study evaluates the quantities of library services provided as well as the accessibility of neighborhood residents to them. The findings show clear tradeoffs between quantity and accessibility with different packages of benefits to residents in different parts of the city.

“…Consumers shopping in neighborhoods with high percentages of black or elderly residents have been shown to pay more for groceries while shopping in dirtier stores with a more restricted selection of foodstuffs than those available to consumers shopping in other areas of town (Hall 1983). Additionally, studies have found that accessibility to landscapes offering a variety of amenities-such as parks, employment, or public transportation-is frequently wanting in inner-city neighborhoods (e.g., Ottensmann 1980;McLafferty 1982;Talen 1997;Holloway 1998b).…”

Place-based accessibility measures, such as the gravity-based model, are widely applied to study the spatial accessibility of workers to job opportunities in cities. However, gravity-based measures often suffer from three main limitations: (1) they are sensitive to the spatial configuration and scale of the units of analysis, which are not specifically designed for capturing job accessibility patterns and are often too coarse; (2) they omit the temporal dynamics of job opportunities and workers in the calculation, instead assuming that they remain stable over time; and (3) they do not lend themselves to dynamic geovisualization techniques. In this paper, a new methodological framework for measuring and visualizing place-based job accessibility in space and time is presented that overcomes these three limitations. First, discretization and dasymetric mapping approaches are used to disaggregate counts of jobs and workers over specific time intervals to a fine-scale grid. Second, Shen's (1998) gravity-based accessibility measure is modified to account for temporal fluctuations in the spatial distributions of the supply of jobs and the demand of workers and is used to estimate hourly job accessibility at each cell. Third, a fourdimensional volumetric rendering approach is employed to integrate the hourly job access estimates into a space-time cube environment, which enables the users to interactively visualize the space-time job accessibility patterns. The integrated framework is demonstrated in the context of a case study of the Tampa Bay region of Florida. The findings demonstrate the value of the proposed methodology in job accessibility analysis and the policy-making process.
