This is the dataset for project "Improving Access and Efficiency to Transportation Affordable Programs in California" (UCD-CT-FAST-079). This study explores opportunities for improving access to transportation affordable programs by gathering insights from existing income-qualified transportation benefits. Researchers compare examples of these programs to design features of existing non-transportation benefits to characterize opportunities for increased coordination and standardization. The results suggest that there is significant potential for income-qualified transportation program enrollment both for agencies that do not currently offer these benefits and for agencies that already offer them, and that inter-organizational coordination among stakeholders may be essential in implementing successful transportation affordable discounts or subsidies.
