Nahom Beyene Amy Lane Person & Society team Industry partners ... Accessible Transportation is Critical Employment, independence, & social engagement More than half a million people with disabilities cannot leave their homes because of transportation difficulties  One-third of people with disabilities have inadequate access to transportation 
46% of people with disabilities, compared to 23% of people without disabilities, reported feeling isolated from their communities  Lack of transportation (29%) was only second to a lack of appropriate jobs being available (53%), as the most frequently cited reason for being discouraged from looking for work  1-month delay in nursing home admissions could save $1.12 B annually (US)  Apply IT advances in methods and technology to transportation Focus on need & capability, not diagnosis
Core Principles for Affecting Change Technology, as appropriate for end users Leverage existing advances in Intelligent Transportation Systems (ITS) End user input early and often Universal Design Primary: Any older or disabled user Secondary: Any user who could benefit from the technology Successful examples: Real-time arrival data from automated vehicle location (AVL)
VPG MV-1 Transit Status Quo Funding, relationships, & complexity Size and complexity of transit systems Consistent funding challenges Difficult to foster collaborative consumer participation Paratransit is very expensive More integration of accessibility into mainline components needed Transit: Travel Chain Use IT at the system level: best practices, accountability,
etc Citizen Science (Paolos, 2008) Rich media evidence for large-scale impact End user data collection Personal value/interest Opt-in Stationary works well Citizen weather stations Mobile now possible Air pollution
Access barriers www.neighborhood-networks.net www.zexe.net/GENEVE/map.php Collaboration is Attainable ParkScan.org Users provide pros & cons In 2007 alone: 425 registered users 1,531 observations 68% of contributed issues were addressed by the City City is an active participant
Transit Making it Useful Part I: Citizen science website Part II: Mobile, tailored, realtime information access Universal design features Open Services (e.g., BART) Database Backend Machine Learning Human-Computer Interaction Personal Vehicles Status Quo Reactive, infrequent, & incomplete Driving assessment: Doctor screening via interviews and
surveys, simulation/simulated driving assessments May not detect changes rapidly, occur infrequently By and large, discount importance of vehicle and environment familiarity Only ~400 Driver rehabilitation specialists (CDRS) in the US Vehicle changes are not cheap or easy to implement Hand controls (with training) start at $2k Conversion vans for wheelchairs start at $20k and rise quickly Driving: Increasing Safety Intervene above an extreme threshold (intervene before crash) Compress the distribution instead (reduce tailgating habits) Unsafe
Frequency Safe Risk Knipling, et al 2004 Behavior & Decisions are Personal Attempting to alter driver-specific outcomes through IT Research shows there are many different driving styles E.g., following behaviors: hunter, flow conformist, etc
Familiarity with own vehicle Controls Vehicle dynamics Vehicle size Familiarity with where typically drive Intersection handling Visual distractions Road type comfort/compensation
Limited cognitive demand for navigation Safe Driving Projects DriveCap: Low-cost aftermarket system that can measure capability on common denominator driving tasks in a wide range of vehicles DriveCap Advisor: Extend DriveCap to provide acceptable driver advice DriveCap Navigator: In-vehicle navigation that learns and supports robust application of rules related to driver capability and vehicle limits Vehicle Transformation: Basic research that enables safer driving through key design and vehicle control improvements Vehicle Enhancement: Basic development that enables safer driving through semi-autonomous vehicle control Policy, payment, acceptance, and related issues throughout
Driver Capability Assessment Autonomous vehicles (1990s - present) Use technology from autonomous vehicle research Augment & supplement capabilities of CDRS Appropriate: Trusted advisor Universal Design: Focus on driver capability, not diagnosis What Does the Data Look Like?
