Mash up transport data for accessible travelling

2. Accessible Travelling
Travelling is listed as one of top difficulties for people
with limitations, impairments or disabilities.
• Pre-trip (route planning, location data and cost etc.)
• On-trip (personal assistance, real time data and
accessibility data of surrounding etc.)
• After-trip (Evaluation, voting and complains etc.)

3. Accessible Transport Data
• Open Transport Data (stations, public transport data
and real time traffic data)
• Other Real Time Data (weather, events or roadwork)
• Open Accessibility Data:
– Open data that can improve the accessibility
– Data related to accessibility information (toilet, lifts, ramp,
wheelchair space in bus or trains etc.)
– Data can help people with special needs

5. Solutions
Proposed Solutions:
• Accessibility data schema standardization
• Open the accessibility data
• Data extraction and conversion (existing data)
• Crowdsourcing the accessibility data
• Linked Data
• Monitoring framework and evaluation
applications

6. What We Have Done?
• RailGB http://m.railgb.org.uk/
– A demo application of open accessibility data
(London tube and railway)
• SymbolNet http://symbolnet.synote.org/
– Crowdsourcing the open accessibility data
• OpenAccessibility (Next Step)
– Data hub for publishing the open accessibility
data
– Publishing the API for public access

7. Future Work
Linked Open Accessibility Data Framework
• Crowdsourcing accessible transport data
• Data Integration Model
– Open Accessibility Data Ontology
– Linked Data (Linking to other resources)
• Data Monitoring and Evaluation Model
• Applications (Decision Support Systems or
Recommendation Systems)
