“…A higher number of blocks suggests more local streets and a regular street network (CMAP, 2012). In addition, a pedestrian environment index (PEI) was also included in the data using the work of Peiravian et al (2014). The PEI is a composite index that combines land use diversity, population density, commercial density, and intersection density.…”

This paper examines the role that public transport last mile problems play in mode choice decisions of commuters, while controlling for trip, built environment, and decision maker related variables. Last-mile problems arise due to lack of adequate connectivity between transit stops and trip origin or termination points. The paper is motivated by previous literature which has pointed out that high-quality public transit needs to consider end-to-end connectivity from trip origins to destinations. In contrast to previous work on transit last mile problems which has focused on physical distance and sidewalks to transit stops, we consider a wider range of area factors including transit availability, job accessibility, parking costs, the quality of the pedestrian environment and risks to pedestrians from vehicular traffic, and social characteristics such as street-level crime. Using a discrete choice model, our goal is to unpack ways in which such factors contribute to the last mile problem in home-based work trips, while controlling for these wider range of factors as well as the usual variables such as cost and trip time that inform mode choice. We find that the prevalence of non-domestic violent crimes reduces the odds of using all types of non-motorized alternatives as well as transit that is accessed either by walking or driving. Using compensating variation to measure welfare changes, we show that there are significant benefits that could be brought to transit service users Preprint submitted to Journal of Transport Geography June 9, 2016 through increasing safety in the transit access trip. By separately controlling for origin and destination transit accessibility, we show that improved destination accessibility significantly boosts transit use to a greater degree than increases in origin level accessibility. These findings argue for improving accessibility and related job densities at employment centers.

“…From another perspective we witness a relationship between population density and line and point thresholds, as shown in Figure 7. This phenomenon is common and expected (52)(53)(54), since, if other conditions remain the same, neighborhoods with smaller blocks (i.e. higher road and intersection density, as compared to larger blocks) tend to create safer environments and thus attract more people, hence higher population density.…”

“…Using the 2010 American Community Survey (ACS) data (50), we find that many travel patterns within the U.S. have power law relationships with the line threshold. Figure 8 As for the point threshold, studies (51,52) have shown that denser road networks, which translate into closer and more compact intersections, support active modes of transportation, including walking. Walking data from 2010 American Community Survey (ACS) supports this idea, as shown in Figure 9.…”

Transportation networks serve as windows into the complex world of urban systems. By properly characterizing a road network, one can better understand its encompassing urban system. This study offers a geometrical approach toward capturing inherent properties of urban road networks. It offers a robust and efficient methodology toward defining and extracting three relevant indicators of road networks-area, line, and point thresholds-through measures of their grid equivalents. By applying the methodology to 50 U.S. urban systems, one can successfully observe differences between eastern versus western, coastal versus inland, and old versus young cities. Moreover, we show that many socioeconomic characteristics, as well as travel patterns, within urban systems are directly correlated with their corresponding area, line, and point thresholds.

“…In other words, even at the same parcel or census block, the accessibility might not be identical. Since aforementioned methodologies used zone-based analysis, they might have MAUP [41][42][43][44][45]. However, the cell-based method utilized in this study compensates for MAUP by use of controllable cell size.…”

Many municipalities in the US are deploying urban planning approaches to resolve problems caused by urban sprawl, particularly the lack of support for physical activity. Although a variety of perspectives on the relationship between physical activity and built environment exist, many studies have suggested objective and reliable measures of urban form that encourage more opportunities for physical activity. Thus, based on the research context, this study builds a Geographic Information System (GIS) model using geospatial dimensions, yields a visualized map ranked by composite scores, and reveals the spatial distribution of quantified cells. Through the Jacksonville case study, it is shown that the GIS-based visualization method provides an expanded set of tools that can help urban planners and public health professionals understand the relationships between urban form and potential for active living. Consequently, these map-based visualized results provide valuable information to health and public policy professionals to coordinate and resolve mutual challenges.
