People-Focused And Near-Term Public Transit Performance Analysis, Alex Karner
People-Focused And Near-Term Public Transit Performance Analysis, Alex Karner
Journal of Public Transportation
Public transit ridership forecasts have long played a role in understanding the potential success of a policy or investment, but their limitations have led researchers and practitioners to identify other performance analysis approaches. Accessibility, or the ease of reaching opportunities, has become very popular and widely used for this purpose. But commonly used accessibility measures also embody weaknesses that are seldom acknowledged; these limit their utility for truly understanding the benefits of transit investments. In this paper, we identify the pros and cons of these competing approaches and offer a third strategy. Specifically, we describe how revealed travel behavior data, …

SMU Data Science Review
“Project Sidewalk” is an existing research effort that focuses on mapping accessibility issues for handicapped persons to efficiently plan wheelchair and mobile scooter friendly routes around Washington D.C. As supporters of this project, we utilized the data “Project Sidewalk” collected and used it to confirm predictions about where problem sidewalks exist based on real estate and crime data. We present a study that identifies correlations found between accessibility data and crime and housing statistics in the Washington D.C. metropolitan area. We identify the key reasons for increased accessibility and the issues with the current infrastructure management system. After a thorough …

Suburban Sustainability
Sidewalks are a critical part of sustainable transportation systems, supporting pedestrian travel and healthy physical activity. Presence and quality of sidewalks is a significant predictor of perceived safety and quality of the pedestrian environment. Lack of adequate pedestrian infrastructure data has been identified as a major barrier to large-scale pedestrian planning. Sidewalk presence, width, and surface condition are identified as important indicators of facility quality and accessibility. Georgia Tech is deploying an Android tablet application to automatically generate spatial sidewalk inventories, automatically assess sidewalk quality, and prioritize sidewalk repairs. The research team has collected field data on sidewalk segments across …
