Research Stemming from the Regression Analysis The regression analysis results in some surprising findings about how community and service characteristics affect demand for ADA paratransit demand. Each of these findings suggests possible further research as discussed below.

Poverty Rate and Incomes The model shows a very strong connection between higher poverty rates and reduced demand for ADA paratransit. This suggests research to explore the following: • How and why does the poverty rate in a community depress ADA paratransit demand?

• How are these choices influenced by incomes, family situation, and availability of each mode, especially transit and paratransit service? As in the case of research about poverty rate and incomes, this research would need to look at the choices of individual consumers.

percentage change in fare would be different depending on incomes. A preliminary attempt to create a "poverty-adjusted fare" produced no significant change in the estimated fare elasticity.

Long-Term Trends The chapter about long-term trends noted that several subjects appear as important but hardto-predict components of future ADA paratransit demands. They include the following: • To what extent will future drivers convert to transit and paratransit riders if they eventually experience disabilities that compromise their abilities to drive?

The second of these data sets, as indicated, can only be obtained at reasonable expense through a regional household travel survey. Note that ADA-eligible people probably compose only about 2% of the general population.44 One member of the study team is currently assisting in the design of the 2006–2007 Chicago area household travel survey, with a large sample size, and it may be possible to include a question or two about ADA eligibility and certification in that survey.
