“…Based on their literature review, Mamun et al (2011) chose three methods of measuring accessibility, and then proposed weighting factors for individual method to come up with a composite measure for a case study in Meriden, Connecticut [39].…”

This study reviews the transit accessibility concept and describes its empirical application in Richmond, Virginia, USA. The transit accessibility concept involves multiple components. Each component has several measures; the selection of which measure to use depends on unique local circumstances. Geographic Information Systems (GIS) and statistical tools are utilized in this study. It has been found that, although the Greater Richmond Transit Company (GRTC) provides a reasonably good transit service inside Richmond City, its existing hub-and-spoke transit system is not aligned well with new and complex travel patterns (including suburb-to-suburb travel patterns), and thus needs to be restructured in the near future.

“…Bertolaccini and Lownes (2015) also developed an automated method to evaluate the changes in transit accessibility through the day using only GTFS and population data to make it easier to find relevant datasets. Al Mamun and Lownes (2011) reviewed different methods and proposed weighting factors for individual methods to formulate a composite index of public transit accessibility.…”

“…Most studies of social equity and public transit accessibility entail an aggregate comparison between transit need and transit supply. In these studies, transit need is often established over space as a measure of socioeconomic status in neighborhood units while transit supply is typically measured at the neighborhood level as the ease of reaching transit facilities (Murray et al, 1998;O'Neill, Ramsey and Chou, 1992;Moniruzzaman and Páez, 2012), reaching transit facilities weighted by level of service (Rood and Sprowls, 1998;Henk and Hubbard, 1996;Ryus et al, 2000;Hunter-Zaworski, 2003;Drew and Rowe, 2010;Al Mamun and Lownes, 2011;Currie, 2010), or reaching actual destinations with transit (O'Sullivan, Morrison and Shearer, 2000;Lei and Church, 2010;Foth, Manaugh and ElGeneidy, 2013;Páez and Farber, 2012;Farber, Morang and Widener, 2014). One drawback of these studies is that transit need is poorly characterized by zonal population characteristics since different population groups demand travel to different types of destinations at different times of the day.…”

“…Public transit accessibility has been extensively studied from the perspectives of station access (Murray et al, 1998;O'Neill, Ramsey and Chou, 1992;Moniruzzaman and Páez, 2012), average service frequency (Rood and Sprowls, 1998;Henk and Hubbard, 1996;Ryus et al, 2000;Hunter-Zaworski, 2003;Drew and Rowe, 2010;Al Mamun and Lownes, 2011) and origindestination travel times (O'Sullivan, Morrison and Shearer, 2000;Lei and Church, 2010). These can all be considered static measures of access, since the score for a particular location does not vary temporally.…”

Despite its importance, temporal measures of accessibility are rarely used in transit research or practice. This is primarily due to the inherent difficulty and complexity in computing time-based accessibility metrics. Estimating origin-to-destination travel times that include the "last mile" of travel between the transit network and actual start and endpoints of the trip is technically difficult. Not only do such estimations require multimodal network structures, they also require detailed knowledge of transit schedules and sophisticated algorithms for calculating shortest paths using such inputs. Recently, new standards for sharing transit schedules and geographic data, namely the General Transit Feed Specification (GTFS) have prompted innovations in the analysis of complex transit travel times using the Esri ArcGIS package with the Network Analyst extension. With continued development of the analytical capabilities of network analysis functionality, this project assesses spatiotemporal dynamics in transit supply through an investigation of scheduled travel time variability.This report consists of a collection of three stand-alone research papers. The first defines a new data object, the public transit travel time cube, and demonstrates its use in measuring changes in transit provision over time, changes in accessibility to jobs, and the impacts of bicycling on the last mile problem. The second paper consists of a study of temporal mismatch between observed travel patterns and the spatiotemporal patterns of transit supply in the Wasatch Front. The third paper expands the food desert literature by measuring temporal fluctuations in food accessibility over the course of a typical day, and examining the trends for disparities between socioeconomic subgroups. Our findings indicate that time-based measures of transit accessibility provide more nuanced abilities for us to understand how people are impacted by temporal variability in transit provision. 17.
