Please join us tomorrow at the Change Seminar.  Anat Caspi from the Taskar
Center for Accessible Technology (TCAT) will be joining us to talk about
equitable pedestrian wayfinding.

*What: *Equitable pedestrian wayfinding

*When: *Tuesday, Nov 15

*Where: *The Allen Center, CSE 203


As pedestrians, we each experience the built environment differently. Our
physical abilities greatly impact our access to the world and resources
around us. Equitable pedestrian wayfinding is crucial for a barrier-free
city, where people with different abilities can independently access
customized, relevant, and up-to-date routing information. Pedestrians
present heterogeneous information requirements consisting of static and
transient information ranging from elevation changes to curb ramps to
transient sidewalk surface conditions. However, such data, including the
location of sidewalks, are generally unavailable in a user-consumable
format. Moreover, existing routing solutions primarily optimize for
distance, for instance, offering inappropriate routes with steep inclines
that are unusable by many manual wheelchair users. A data model for
equitable pedestrian wayfinding must flexibly support an annotated
pedestrian network: a connected graph model that can be visualized and
populated with data to parametrize a personalizable cost function. In this
talk, we will present the current AccessMap capabilities (and discuss those
in progress) that enable ability-based pedestrian routing.
