  • Data Collection Methods

    When choosing a centerline connected graph layer representation for the OpenSidewalks schema, one of the many motivations was the ability to construct a graph from simple observations and inputs. Further, in the case of the non-motorized transportation layer, the graphs allow as few or as many attribute overlays as the data producers are able to…

  • AVIV ScoutRoute App

    The Volunteerism App for Pedestrian and Accessibility Mapping Imagine a world where you can contribute to the accessibility of your city simply by answering a few questions on your phone. Introducing AVIV ScoutRoute, an app that leverages the power of crowdsourcing to gather critical pedestrian and accessibility information. This innovative platform allows players to engage in…

  • OpenSidewalks Schema

    The OpenSidewalks Schema is a proposed open pedestrian transportation network data standard for describing and sharing pedestrian network and pedestrian network-adjacent data. The OpenSidewalks Schema promotes an explicit network (graph) model wherein its primary data entities can be deterministically transformed into graph edges and graph nodes. Therefore, OpenSidewalks Schema data represent a traversable and graph-analyzable…

  • iOSPointMapper

    The Taskar Center for Accessible Technology aims to alleviate mobility challenges faced by people with disabilities. One initiative towards this goal is the development of iOSPointMapper, designed for standardized data collection to enhance reliable sidewalk mapping. The data collected through the application can eventually be consumed by other applications that provide guidance for accessible navigation.…

  • Annotations for Pedestrian Environment (APE)

    Elevating the ambitions of TDEI and OpenSidewalks, the Annotations for Pedestrian Environment (APE) dataset addresses a critical urban mobility challenge: accurately mapping pedestrian pathways, including sidewalks and crossings. This project introduces a novel training dataset featuring aerial satellite imagery, street map imagery, and precise annotations of sidewalks, crossings, and corner bulbs across various cities. The…
