3. Transportation Disadvantage
Unable to drive due to disability or a medical illness
Unable to afford a vehicle
Lack access to public transportation
Limited access to other transportation options
Transportation Disadvantaged:
Older adults
Persons with low income (environmental justice)
Individuals with disabilities

4. Implications from Practice and Research
Travel cost (travel time) rather than access controls latent demand
Only currently observed trips matter
Everyone can travel if/when desired to any activity
Spatial and temporal deficiencies in current system unimportant
Mainly work trips matter
Off-peak trips of limited concern
Specialty services and public transportation should serve all transportation disadvantaged populations regardless of housing and employment location.

5. Proposed Solution
A daily transportation plan, diary, and journal for environmental justice communities to capture data
Planned trips
Desired activities
Completed trips
Lived experience of transportation mobility
Test feasibility of using an app for collecting transportation-related data among older adults and homeless mothers
Enhancements over current practice:
Examine the gaps in activity fulfillment due to transport limitations (i.e. latent demand)
Transportation mobility experiences and their impact on quality of life
Health/well being

Comparison of Transportation Data Collection Strategies
STEVE & NOELLE

8. Conclusions Research gaps addressed
Record and investigate both the actual and desired travel experiences of EJ populations.
Ascertain the causes of differences between actual and desired trips and the temporal and spatial scales on which these differences occur.
Measure the holistic impact of transportation gaps on the lived experiences of EJ populations.
Data collection method and data focused on transportation equity transportation planning and policies
Empirical data can be used to inform policy and public planning decisions:
Local transportation infrastructure and service investments that maximize mobility for this population
Public health and quality of life for this highly vulnerable and largely hidden population
Steve also please talk about how findings will inform recommendations related to transportation services for EJ populations and the implications for livable communities.
