Mobility and Transportation Access
TCAT’s mobility work connects pedestrian-infrastructure data, routing, mapping, transportation analysis, and field collection. Together, these projects help make access conditions easier to describe, review, and use in planning.
Connected work across travel environments
The work spans outdoor and, where supported by the project, indoor environments and on-demand travel services. We build detailed, structured information about the pedestrian network, then connect it to route planning, accessibility preferences, mapping, and transportation decisions.
The goal is not a single “accessible route.” Different people may need different route information and may encounter different barriers. Data and tools should make those differences visible without guessing what a person needs.
Projects and tools
AccessMap Multimodal
Route-planning work that presents accessibility information in ways that can be shaped around different mobility profiles and route preferences.
OpenSidewalks Data Schema
A shared structure for detailed pedestrian-network data and the attributes needed to connect features across mapping and analysis tools.
Transportation Data Exchange Initiative (TDEI)
Shared transportation data infrastructure for connecting standards, mapping, workspaces, and public-use pathways.
Washington State Proviso / OS-CONNECT
Statewide pedestrian-network work connecting data collection, review, and accessibility mapping under the Washington State effort.
iOS Point Mapper
A mobile mapping tool for collecting details about pedestrian infrastructure in the field.
AVIV ScoutRoute
A mobile field-survey app for recording observations about pedestrian features through project-specific quests and workspaces.

What connected data can support
- More complete and detailed pedestrian-network information.
- Route planning that can account for individual preferences and mobility profiles.
- Community mapping and review workflows with clear project context.
- Shared standards and infrastructure that help projects exchange information.
- Evidence that can inform planning, safety, and equity decisions.
- Pedestrian-network work relevant to Growth Management Act planning and ADA transition planning when incorporated into the responsible agency’s process.
These applications depend on the project’s data, review practices, and decision context. Mapping or field collection alone does not replace a formal inspection or agency determination.
